I am new to the Mac world, so please bear with me. I have freeze up issues with beachballs delux on my mid 2011 21.5 iMac with 2.5 GHz Intel Core I5 processor. When I run repairing permissions, it resolves the problem for a few days, but then returns back to the same problem. It says "Library/Preferences?Com.apple.alf.plist. Should be 80, group is 0
Can anyone tell me how to resolve this freeze up problems? I origiginally had Lion operating system and when I upgraded to Mountain Lion the issue was better, but did not totally cure this.
Open Finder - Go - Go to Folder and copy and paste:
Hit enter so the file is located. Then move the folder to the Desktop and logout and log back into your user account and test. Apparently that plist file is corrupt and will be re-created when you log back in.
