Permissions Question

Have you tried deleting "com.apple.alf.plist" in Macintosh HD / Users / YOU / Library / Preferences / yet? It will be recreated upon need.

Why do you repair permissions in the first place?

 

Some people repair, or recommend repairing permissions for situations where it isn't appropriate. Repairing permissions only addresses very specific issues. It is not a "cure all" or a general performance enhancer, and doesn't need to be done on a regular basis. It also doesn't address permissions problems with your files or 3rd party apps.

If repairing permissions results in error messages, some of these messages can be ignored and should be no cause for concern.

Mac OS X: Disk Utility's Repair Disk Permissions messages that you can safely ignore​

 

First of all, Repair Permissions ALWAYS reports that some files "should be" something else, but doesn't do anything about it. All is well: you can ignore that.

Secondly: the presence of Recovered Files has nothing to do with Permissions, but is to do with poor housekeeping by some apps. On reboot, those files are put into the Trash as "recovered files". This is not something you need to worry about or do anything about, short of emptying the trash. OS X has already done the tidying up.

 

That plist file is in /Library/Preferences (top level of hard drive), not ~/Library/Preferences, (user Library folder).
