When I went in store the other day, to get my disk-drive looked at the Apple guy fired at me for the following. (BTW this was an Apple franchise company called Solutions Inc.) I had disabled Spotlight via the Core System file I had been in the Core System file I had used CMD+C/V and CandyBar to change my icons I had used Loginox to change the login background and logo I had used 3rd party applications to change the normal operation of a Mac I had iStat Menus I had Bartender (hiding various system menubar icons) I had Alfred (though he didn't comment much on this) I had Hazel I had Sophos (anti-virus). I had delayed launcher. I had several others... Is this normal? Did I just get someone on an off day? Next time I go in, do I need to disable all of the above temporally? Should I really not use any of the above? Is it just because I went to a reseller? Are Apple stores different? Could I bypass disabling all of the above just by making a secondary account?
