Mac OS X 10.5.1: Admin rights, audio missing after update, fixes

Admin rights missing after update, fix Some users have reported an issue after updating to Mac OS X 10.5.1 that should have only been occurring after the initial upgrade to Leopard (Mac OS X 10.5) according to Knowledge Base article #306876 -- a loss of appropriate rights for administrator accounts, which inherit standard account rights.

A report from MacFixIt reader Norman Burns:

"Since updating to Leopard 10.5.1 I appear to have lost all of my administrator rights, the name and password that I have been using since 10.1 are no longer recognized and it is not possible for me to repair disk permissions."

The solution listed in the aforementioned Knowledge Base article is a multi-step process that involves using the Reset Password command while booted from the Mac OS X 10.5 (Leopard) DVD. However, this solution has proven fruitless for some users, who continue to lack administrator rights in so-enabled accounts. These users are finding that the only reliable fix is to perform an Archive and Install of Leopard.

Norman followed up:

"I tried all of the suggestions last night but could not get any to work, so it was Archive and Install and everything works now. The restoration of files etc is a regular pain."

Sound lost after update, fix Users have also reported a loss of audio functionality after the update to Mac OS X 10.5.1 -- an issue that can sometimes be resolved by deleting the following files:

• /Library/Caches/com.apple.Components2.LocalCache.AudioComponents
• /System/Library/Extensions.mkext
• /System/Library/Extensions.kextcache

then restarting. (Thanks to MacFixIt reader Pasi for this fix).
