applications crashing after 10.8.4 update
I've had multiple applications crashing either immediately on opening or within a few seconds. Apps include Mail, Safari, Chrome, Numbers, Pages and others. This seems to coincide roughly with updating to 10.8.4.
I've restored from Time Machine Backups 3 times, re-installed Mountain Lion (and 10.8.4) from scratch at least once, ran Disk Repair and Repair Permissions from the recovory parition multiple times. After a restore or re-install, the problem appears to go away for couple of days but then rears it's head again. I've ran a full scan of the HD using Drive Genius and it seems fine (hard drive is not original, 750 GB Seagate Momentus XT, the "hybrid" version). I've also downloaded the free version of Norton AV and scans fine as well.
I have and use Drive Genius but I've no way to test hardware such as RAM and such. Just wondering if there's any *free* hardware utilities that can fully test the CPU, RAM, etc. Need to get to the bottom of this....this 13" MacBook Pro is not even a year old. Needing to know if I've got a failing HD or if it goes deeper than that.
