Hello, I'm having issues with freezing and the 'spinning ball' and not sure what to do. I have an older Mac Pro (early 2008) running OS X 10.8.5. The hard drive is 1T but pretty loaded up with software. I run mostly music software (Pro Tools) and all of a sudden it starts freezing the entire computer randomly, I have to do a hard reboot, not good. It will freeze with smaller programs, not just Pro Tools. I run disk utility, verify disk, repair permissions and when I turn the machine on the next day, all the same errors/repairs come up. It never seems to actually repair anything. I ran diskwarrior and it apparently fixed many issues, but highlighted in red were about 200 items that had property list data damage (can't be repaired) and 10 resource data damage (can't be repaired). Do I have to delete all of these items and if so, will the programs they're associated with still run? Any insights on how to stop this random freezing? Thanks!
