ACL Found But Not Expected Weirdness

If you see a bunch of these messages when repairing permissions, here's how to deal with it:

if you try to repair permissions and get a bunch of acls found but not expected

to fix this some chmod commands need to be executed in the terminal.

Essentially open up a terminal and do the following:

cd /
ls -le

look at the Applications and Library folders in the listing and you should see they have specific ACLs. On one of my machines the Applications folder had 2 and the Library had one. On the other both had just one.

to remove these ACLs do the following:

sudo chmod -a# 0 "/Applications"
sudo chmod -a# 0 "/Library"
