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.

iMac (21.5-inch Mid 2011), OS X Mountain Lion
