New Airport Extreme Crashes Wireless Tiger Clients

I've spent most of Christmas Day trying to figure a way out of this mess. I even downgraded my old Powerbook G4 to Panther, only to discover that it--initially--had no support for WPA security (doing the normal upgrades to it now via Ethernet). Not sure why it seems that every time I buy a new piece of Apple gear, it doesn't cooperate very well with older Apple gear. I understand that time moves on (and Apple wants us to as well), but one expects things like basic wireless in a working Mac to continue working with newer Apple wireless routers. But no.

I initially thought the problem might be my new WDS setup, but that's not the case. The kernel panics persisted, whether I disengaged WDS or not.

The Airport Extreme Base Station in its current firmware incarnation (7.5) causes kernel panics on ALL wireless clients running Tiger 10.4.11. This is confirmed by multiple users on the Apple Support Boards:

My Apple Tech confirmed (early November) that there is a known problem with the new Airport Extreme Dual Band Base Station causing kernel panics on computers running Tiger (only when connecting wirelessly via an Airport card -- not when connected via Ethernet cable). Apple Engineering has been notified and has not -- as yet -- released a software update to Tiger. Based on some customers' reports, we tried disabling the Guest Network on the base station, but that didn't work for me. Has anyone figured out a work-around besides 1) the ethernet cable and 2) upgrading to Leopard?

[From Apple - Support - Discussions - Kernel Panic when Running Tiger ...]

One user managed to get Apple to send him a Leopard install to address the issue:

Here's my experience. Ran two iMacs with Tiger 10.4.11 and a new iMac Intel Core Duo with an Airport 801.g Extreme. Alls well. I upgraded to an Airport 801.n and all **** broke loose with Unresolved Kernel Traps (UKT) on both Tiger machines. I managed to obtain Leopard from Apple and will upgrade each Tiger machine a couple of days apart to be sure I don't have any more UKTs. Then I will reinstall the Airport 801.n and see what happens. If I can believe what Apple Support has told me my problems should be solved. I should know by end of this coming weekend.

[From Apple - Support - Discussions - Kernel Panic when Running Tiger ...]

So I put in a service call to Apple and spoke with a rep today; the rep didn't offer a Leopard install like they did for the other user, and they didn't even admit that there was a known problem:

No dice. Just got off the phone with Apple and their solution for me was to go into the Apple Store. He said it was a computer issue...not the AEBS. I even brought up this thread (i.e., Tiger incompatible with new AEBS) and that other users said that Apple had acknowledged this problem. He said he had not heard that and that it was my computer?

Keep in mind that I told him that both my G4 machines are running Tiger (Powerbook and Mac Mini) and both are kernel panicking with the new AEBS.

So, I obviously didn't get the good support that you received...

[From Apple - Support - Discussions - Kernel Panic when Running Tiger ...]

I've basically tried everything (including doing Leopard installs using Target Disk mode), and nothing is really working (the G4 versus Intel architecture creates problems--i.e., the GUID versus APM). I either must get a Leopard Retail disc from Apple or wait for them to officially acknowledge the problem and issue a firmware update. Arggggghhh! My Powerbook is now running 10.3.9 (Panther) after the updates and is doing fine on the new AEBS, so this PROVES it's Tiger that is not compatible with the new Airport Extreme Base Station (802.11n). The Mac Mini is dead in the water at the moment in terms of wireless connectivity (I have the Airport turned off...and no more panics). I have ordered some cheap Cat-5 cable, which should be here soon and keep the Mini running until the firmware update shows up. Apple, your users really shouldn't have to go through such nonsense.

FOLLOW-UP on 26 DEC 2009:

As a follow-up, my issues were solved by installing Leopard on my G4 machines, which was not easy. See my post below on the Apple Discussions thread:

I can confirm now--as have others here--that it is definitely the Airport Extreme Base Station (802.11n) that is causing the kernel panic problem with Tiger. It will also not cooperate with Panther 10.3.9, IF you install the AirPort Extreme Driver Update 2005-001 update:

http://support.apple.com/kb/DL426

I downgraded my Powerbook G4 Aluminum 15" to Panther and had it working well at 10.3.9 until I installed the above driver update, so this driver (or some code within it) is the culprit; obviously, it hung around in Tiger but changed in Leopard and Snow Leopard (hint, hint, Apple).

I have now managed to update my old G4s (through much effort) to Leopard and both are cooperating nicely now with the Airport Extreme Base Station. I suspect Apple will update the driver eventually, but if you're having issues...go back to Panther (w/o the aforementioned driver update) or upgrade to Leopard if your system will install/run it.

FWIW, I installed Leopard on my old G4 Mac Mini (with 512 MB RAM) using Target Disc mode from the Powerbook running the install DVD. Leopard would not install any other way on that machine. Good luck all!

New Apple Keyboard!

Well, this New Year's Eve, I stupidly spilled coffee into my old Kensington keyboard, while typing away over at GtrOblq. Even though I took it apart and used a hair dryer on it, the bottom row of keys refused to come back to life. So, we did a mad dash to the nearest Best Buy before they closed for New Year's Eve, and I purchased one of those slender, new Apple keyboards. We didn't have time to make it to the Apple Store at La Cantera, because everything closed at 6 pm.

Man, what a great keyboard! I barely feel like I'm typing, and it's so thin that I don't even need a wrist support! Yeah! The front housing is made of Aluminum, so it seems sturdy. I looked at the other Mac-compatible keyboards, but they all came with a mouse and were at least $20 more than the Apple keyboard! So much for that theory that Apple is more expensive.

PC User Compares Leopard to Vista

Leopard is the New Vista, and It's Pissing Me Off:

Surprise, surprise! A PC Magazine columnist, who claims to worship OS X 10.4 (Tiger), is more or less calling Leopard OS X 10.5 unfit for release in much the same way Vista was unfit (and is still unadopted by the PC faithful).

Let's break this idiot's diatribe apart piece-by-piece, shall we?

Let's see, Tiger crashed—oh yeah, NEVER. Ten months and I'm installing everything from production-level Office for the Mac 2004 to 0.x releases of VLC, Seashore, and Ecto—even betas of Firefox and Parallels. Whatever my nerdy little heart desires. I've had those early apps crash, but Tiger never faltered.

First of all, BS! All OS's crash, though I proclaim that OS X is typically more stable than Windows, regardless of the version. I guarantee you that Tiger version 10.4.0 crashed MORE than version 10.4.5, and so on. Now the latest version of Tiger (10.4.11) has some quirks that tick me off in a few included apps (like making me use Safari 3.x, for example), but what we're seeing here from this guy is a little overstated.

The first version of anything is going to have bugs. All developers rely on the cutting-edge crowd to find the junk in their code that they have been unable to find. Basically, if you buy and install the first version of anything, you're paying to be a beta tester, whether you like it or not!

Later on, the goon states:

A month of using Leopard with the same software I had under Tiger and the OS has dumped six times. That's six cold reboots for Oliver. Apple isn't even honest enough to admit that Leopard is crashing: The OS just grays out my desktop and pops up a dialog box telling me I've got to reboot. Like the whole thing is my fault. I even snapped a picture of it. After all, I HAD PLENTY OF CHANCES! And all my complaints, mirrored by online forum traffic, are the same complaints I heard about Vista when it first reared its unbaked head.

Next lesson for this noob. Developers of software for a particular OS MUST CATCH UP WITH THE LATEST OS RELEASE! If they don't, IT'S NOT APPLE'S FAULT! Hello, are you listening, Oliver? Every time I've upgraded to a new version of OS X, apps that once worked on the previous version have occasionally had problems. I either must wait until the developer fixes the app to work with the new OS version, or I MUST CHOOSE NOT TO UPGRADE UNTIL ALL THE APPS I USE ARE COMPATIBLE. These are all simple, elementary things that every savvy computer user knows. PC Mag...I'm available if you need a writer with a brain who uses a Mac.

Applejack: Getting New Features

Applejack, the command line troubleshooting utility for Mac OS X, is undergoing prerelease testing now for version 1.4.3rc3, which adds a new experimental expert mode. From the read me:

+ Experimental expert mode exists, but is currently hidden until it can be tested further. (see Appendix B). The only well-tested options at this point are the memory test using the included Memtest utility, and the option to disable auto login.

This is great, because among other neat features, it adds the memtest utility as well, which will save you the $1 download charge from its developer.

Memtest and Applejack are must-have utilities, IMHO. Memtest saved my butt on bad memory (via the GUI version in the form of rembr), whereas Tech Tool Pro told me my memory was fine. Wrong! Changed it out and my numerous problems went bye-bye!

Yojimbo 1.2 Quick Input Panel Crap (and .Mac syncing)

MacUpdate: Yojimbo Reviews: I like the app, but the Quick Input F-key keeps saying:

'Yojimbo could not communicate with the Quick Input Helper.'

Nothing I've tried seems to fix the error. (9/30/2006, Version: 1.2)

1 Reply To Review:

I finally fixed this problem. Solution: Close Yojimbo, move ~/Library/Application Support/Yojimbo to Desktop, reopen Yojimbo, close it again, return the above folder to its original position.

Now Quick Input Panel works again...go figure.

However, .Mac syncing hasn't worked. I'm hoping this will fix it too.

Google Software Downloads for the Mac

Google Software Downloads for the Mac: "All kinds of great Google goodies for the Macintosh!"

Memory = the source of many problems!

For the last several months, I had numerous problems with my old G4 AGP dual 1.2, which has been as upgraded just about as far as it can go. The problems included recurrent program crashes (especially Safari) and random kernel panics.

I used a little utility called Rember and discovered that a few memory sticks I had were bad. Tech Tool Pro (grumble, grumble) did not catch these errors, so if you think you're having memory issues, please run another utility (apparently, the hardware test disc Apple ships with newer Macs can catch these problems too). You can also run Memtest (which is really the command-line basis of Rember); the author charges $1 to download it (very reasonable given that you can boot in single-user to test MOST of your RAM).

In my case, Memtest wasn't necessary. Rember caught the defective RAM right away, and I narrowed it down to 2 sticks by pulling them one at a time, restarting, and testing with Rember until the errors were gone.

I had 2 bad DIMMs--one at 128 MB and another at 512 MB. So I ordered 2 new 512 MB sticks from OWC (with lifetime warranty). The new memory checked out fine with Rember, and I've had no kernel panics or other major issues since installing it. The old Mac is rock-solid!

Now, how did this happen? I think a Tiger update somewhere down the line didn't agree with those two older RAM sticks. The lesson is to suspect bad RAM (or other hardware) if you're having weird crashes and random panics suddenly.

Yojimbo sync stynk

Apple - Support - Discussions - Yojimbo sync problems ...:

Michael Lafferty over at Apple Support Discussions may have found a trick to help users through problems with Yojimbo syncing. In my own experience, I finally got most of.Mac syncing to work with Tiger 10.4.7, but Yojimbo was the exception. My Powerbook would never update its database using the info from my other Mac.

"Has anyone at Bare Bones Software explained how to reset the Sync Services framework?You can do so by launching iSync, opening the Preferences pane and pressing the Reset Sync History button.

What this does is simply reinitialize the truth, leaving your data intact, all sync clients registered, and creating a condition in which the next synchronization event is considered the first you have ever performed.

Doing that will often clear up what appear to be stalled or incomplete synchronization tasks on the part of any registered client.Here is a link to a document which explains how this 'hidden' framework operates: http://developer.apple.com/macosx/syncservices.html "

I've had recurring Safari crashes that are quite annoying. Most of them appear related to the Flash Player plug (both version 8 and 9 for OS X); they all appear similar to the crash report line above.

Apparently, it's a bug in Webkit, FLash, or some synergistic malfunction. Safari crashes about 5 or more times a day. And it's weird, because though it says it has crashed I still have to force quit Safari.

iStynk and .Mac Stync

Of all the things I love about OS X and Tiger (and the list is great), I can't say I'm very fond of the syncing architecture. It's fairly lame damn it. I recently bought a .Mac membership ($99 annually) to take care of my email, web hosting, and syncing for multiple Macs. The only problem is that the syncing part is stynking. And considering I'm not getting what I paid for, it's really ticking me off!

.Mac Support has been working on my bookmark syncing problems since April 24, 2006--it's now May 15, 2006; their most recent response to my latest inquiry was:

Thank you for your patience as we work to resolve this issue.

.Mac Support engineers are still hard at work seeking a resolution for the issue you have reported. Currently, they are reviewing the logs and your account configuration. We appreciate your patience as we strive to make your experience with .Mac a more enjoyable one. Rest assured we have flagged your request for follow up and will contact you immediately once we have more information for you.

So I've tried some other 'fixits' while I wait for their lightning-fast customer support; You can view the entire procedure here at the Apple Discussion forums. Here's my summary:

1. I unregistered all my computers via Sys Prefs.
2. I turned off sync via the web interface for Address Book and Bookmarks. Then I deleted all the Contacts and Bookmark (the generic Apple bookmarks) entries via the web interface.
3. I deleted all .Mac keychain entries from the Keychain app.
4. Deleted "PendingNotifications.plist" and "conflicts" via my /Library/Application Support/ directory. I left "clientdata" alone this time (I tried deleting it last time and it didn't do anything).
5. I reset my phone and resynced it via iSync. My calendars came across, but for some reason my contacts won't go over now (on the phone).
6. Before syncing with .Mac, I went to my iDisk and checked the Bookmark.xml file. It was still there at 84 KB. I could actually open it with BBEdit and see that it's still the generic Apple URLs. I couldn't delete the file though.
7. I went to Sys Prefs at the Sync tab and turned on just Bookmarks. It was already set to "Manually" sync. When given the option, I selected "Replace data on .Mac". It seemed to sync and gave the green check mark, but then it gave me the "There was a problem with the sync operation. .Mac login failed." message. I went ahead and resynced the bookmarks again without error this time.
8. I went back to mac.com and turned on bookmark syncing and selected merge. Now my bookmarks are completely empty again online - at least the generic Apple bookmarks are gone. I went to Sys Prefs and selected reset sync data to try again. The bookmark.xml file on my iDisk is now 1 KB in size.
9. So I went ahead and tried syncing everything else again. My online contacts will not sync now. Don't know why. I'm assuming this means nothing else is syncing.

So I lost my online contacts and my phone contacts--very important--more so than bookmarks on .Mac! So I found this online solution thanks to Josh Blander. I just deleted my entire ~/Library/Application Support/SyncServices directory and restarted. My phone was back and my .Mac contacts synced again after that. My bookmarks, however, were still in the toilet--no syncing permitted. I have no clue why they won't sync. They'll sync if I create a new OS X account and add a trial .Mac account. But not with my PAID account.

10.4.6 Update Problem and Fix

When I applied the 10.4.6 Combo updater for Tiger I couldn’t boot up again. The first symptom something was wrong was when I hit the restart button after installation; the thing hung up so I had to do a hard reboot. Afterwards, it would hang once the progress bar of the “Welcome to Macintosh” dialog went all the way across, or in other cases the desktop and cursor would appear and nothing else (no menu bar, dock, etc.).

Running the Applejack suite did nothing to fix the issue (in single-user mode), and I couldn’t boot up in safe mode. Reinstalling the update from another partition didn’t work either.

So while booted in the other partition, I deleted the cache files. The next reboot was fine, and it has been fine since.

The Mysterious Library Alias

Many of you in Tiger may have noticed the problem discussed here.

Specifically, a new generic file alias shows up in under Network in the Finder. Apparently it has something to do with NFS. A user on the above forum wrote:

The network Library contains items that are available to all users on your network. It has been around since at least 10.1. You would only use this folder if you part of a network being managed with OS X Server.

From Mac OS X Server Administrator’s Guide:

"Adding System Resources to the Network Library Folder

This Library folder in the Network globe is included in the system search path. This gives you the ability to make available, from the network, any type of system resource that resides in the local Library folder. These resources could include fonts, application preferences, ColorSync profiles, desktop pictures, and so forth. Mac OS X accesses the network Library folder before the local Library folder, so network resources with the same name take precedence. You can use this capability to customize your managed client environment."

So just ignore it. It represents network services that aren't available to you.

Anyway, the important point is how to fix it from another user:

>>>When I click on the Network icon in the Sidebar the window shows "Servers" and an alias called Library. If I click on it the system tells me the alias is broken. I don't know what this file is for.

I deleted the file but I had to log in as root to do it. After that I could login to and user on my Mac and the file was gone. After I did a restart it came back again. Anybody know what this file is?<<<

To prevent it from comming back, edit "/System/Library/StartupItems/NFS/NFS" and place a # in front of the line:

ln -s /automount/Library /Network/Library

As shown below....

nfsd ${arguments}
fi
##
# Start the automounter
##
if [ "${AUTOMOUNT:=-YES-}" = "-YES-" ]; then
automount -m /Network -nsl -mnt ${AUTOMOUNTDIR}
# ln -s /automount/Library /Network/Library
automount -m /automount/Servers -fstab -mnt /private/Network/Servers -m /automount/static -static -mnt
${AUTOMOUNTDIR}
ln -s /automount/Servers /Network/Servers
#
# Hint that the name /Network should be localized:
#
ln -s . /Network/.localized
fi
#
# Leave a mark upon completion of the automounter startup:


Sharing iTunes and iPhoto on One Machine

This must be one of the biggest pains in the world. I don’t know why Apple doesn’t address this better.

Sharing a single iTunes (or iPhoto) Library is very tough, because of separate user accounts and permissions issues. If you do a search on Google, there are about 8-gajillion methods for achieving this; most of them are too hard and many of them don’t work. The one I had previously used under Panther required setting up a new group with NetInfo Manager.

Even Apple’s current support document on the issue isn’t 100% right. However, (as usual) digging through the discussion board (where Apple plays no official part) I was able to find a key omission in Apple’s version. The original can be found here, but I’ve summarized it below:

Holding down the command key & select the iTunes Music folder and drag it to a shared folder along with a copy of the iTunes Library file from your iTunes folder... leave the original Library file where it is... set your iTunes pref. > advanced tab Location is Shared folder.

Set correct permissions on the Shared folder ...

To set preferences using BatChmod is very easy... This compact GUI will perform the same tasks as a 'command line in Terminal ' drag the complete Shared folder with libraries and iTunes Music folder inside to the BatChmod Icon and drop.... check path is correct.... tick if not already.... Owner=R W , Group=R W, Others=R W, then tick 'Apply ownership and priviledges'... 'Unlock' & click Apply... provide password... all done very quick...

The next time you login to the other A/C replace the iTunes Library file in the iTunes folder with the copy in the Shared folder and check the name is iTunes Library without 'copy' added.... start iTunes and set the pref. the same as above.... if you make major changes to library you can swap the library file to the other user A/C the same way.

This didn’t work for my situation, because I want to share our ENTIRE library among users, including playlists and so on. So I eventually pieced together advice from various different sources such as these:

Symbolic links Sharing iTunes and iPhoto Libraries with entire family Using ACL under Tiger (I did not go this route)

A probable avenue for doing this pain free was seen here, but the developer has no demo version available (this software was once donationware). Sounds nice but I won’t pay even $5 for something if I don’t know it will work. And there’s a shareware app called Sandbox that might work as well for doing ACL, but I didn’t try it.

Here’s what I did (basically):

1. Moved /User/Music/iTunes/ directory to /Users/Shared/
2. Changed permissions to allow RWE for all users in that folder
3. Made a symbolic link to the library in each user’s /Music/ folder pointing to the shared folder; note: Path Finder makes doing the above tasks easier
4. Repeated steps 1-3 for iPhoto library as well

It’s working as of now, but we’ll see if I run into any ‘gotchas’. I created a test playlist from one user’s account and then deleted it from another account, so it seems to be working. I can play music from either account. iPhoto is working as well.

Current system.log error messages

What follows are recurring error messages I’m seeing in the system.log, though my current 10.4.5 system seems to be running fine. I’m hoping to address each of these issues over time.

Here are some issues I’m seeing at shutdown:

Acard 6280M and Tiger = BOOM!

I have solved my hanging gray Apple screen of death issue referenced earlier many times on this blog (most recently here - follow the trail yourself back to Jan 9, 2006 when I tried to upgrade from Panther to Tiger 10.4.4 on my relatively old, but heavily upgraded, G4 AGP.

In my last post, I had discovered on the Apple discussion boards information about the Acard PCI Adapter interfering with versions of Tiger after 10.4.2. I figured this was likely my problem as well, as I have that very PCI card and was attempting to boot Tiger off of a drive connected to that Acard adapter.

It so happened that I had a fairly large 120 GB drive still attached to the main ATA bus on the system, so I duplicated my Tiger partition over to that drive. I’ve been cruising along fine since in Tiger 10.4.5. I also emailed Acard the following regarding this issue:

Dear Acard,

I have recently upgraded from Panther to Tiger (10.4.5) and may be having issues with my Acard 6280M. I have loaded the most recent drivers, but the problem still remains.

If I do any system maintenance (cache deletion) or add any new kernel extension, I will get stuck at the Apple gray startup screen. I have to do a safe-boot and then delete the following folder to be able to boot again:

/System/Library/Cache/com.apple.kernelcache/

I perused the file inside that directory and found a line referencing the 6280M. Are there any issues with the current driver and Tiger 10.4.5?

Thank you...

Shane Hendricks

Acard hasn’t yet responded and they may never respond; the current broken driver is version 1.5.7. This driver should work fine with 10.4.2 and below. They did answer some folks on the Apple discussion regarding this topic, which you can read for yourself. They basically passed the buck to Apple, which is bogus. It’s Acard’s responsibility (as a peripheral maker) to support Apple, not the other way around damn it. In another answer, they recommended doing a complete new reinstall and AVOIDING MIGRATING OR UPGRADING from Panther, which is crap for those of us with a nice running Panther system.

Anyway, this problem is solved for me, and my system seems to be running much better under Tiger. Good luck to others with this problem.

More on SystemStarter and gray Apple screen

The plot thickens. Reference, of course, my previous posts on this subject here.

I had narrowed the culprit down specifically to /System/Library/Caches/, which seems to somehow become corrupt after some major system maintenance or modification (i.e., install of a new kernel extension or cache clean up) on my old G4 AGP (Sawtooth).

Some others on the Apple forums had suggested it could possibly be due to my Acard 6280M IDE PCI adapter, which I MAY have ruled out by updating to the latest driver (version 1.5.7.); I’m not 100% sure. I did have some troubles updating to the new Acard driver, but I eventually got it working as well as the previous version of the Acard driver I was using.

However, after reinstalling (once again) Tiger 10.4.5 from the backup I had made and migrating (again, avoiding the root files and folders--which I no longer believe is related to the problem), I installed Applejack and proceeded to clean all the caches in single-user mode to test for problem reproducibility. The system rebooted fine after the Applejack session, but I immediately rebooted again from the Finder and experienced the hang at the gray Apple screen.

Since I had narrowed the problem to /System/Library/Caches/, I decided to go through the contents systematically to find the culprit file or folder. As Murphy’s Law would have it, the very last folder I deleted (after many reboots, gray screens, and safe boots to delete files) was this folder:

/System/Library/Caches/com.apple.kernelcaches/

After deleting this folder, the system booted normally, so I may need to delete this folder after every kernel extension install or system maintenance that involves cache cleaning.

What fun! This obviously MUST be related to my hardware setup in some way, but I don’t know which part for the life of me (maybe it is the Acard, but I can’t understand why). I do have these system.log messages (the first of which I always had in Panther but never had any real issues booting):

Mar 5 09:51:04 localhost kernel[0]: WARNING: ATA Drive claims FLUSH CACHE EXT feature support but does not claim Extended LBA feature support

The above message obviously directly involved the Acard adapter.

Mar 5 09:51:04 localhost kernel[0]: Extension "com.apple.driver.PioneerSuperDrive" has no kernel dependency

The next message listed above is a new one for me. No clue...

So there’s obviously some issue with hardware, because my Mac Mini doesn’t behave this way on Tiger (and obviously for most of the Apple world). My old AGP has been so heavily upgraded that it may no longer be capable of running newer OSs (likely issues with either the Acard or my Giga Designs Dual Processor upgrade card).

Anyway, at least I’ve narrowed it down some to a kernel issue with some part of the hardware.
