Background (Steps Tried):

  • Full Reformat from Recovery System
  • Reset SMC
  • Reset PRAM


I have a latest generation 15" Retina macbook pro that I purchased in February of 2013.


10.8.3 was the most stable operating system I have ever used. I updated to 10.8.4 and the computer began freezing at random intervals throughout the day several times a day. It would happen when I plugged/unplugged HDMI, Thunderbolt, and usb. Even when all 3 were unplugged and I was only using safari, it just would randomly happen.


I thought perhaps I needed to reformat. so I backed everything up, booted to the recovery center, and completely reformatted the computer. It downloaded 10.8.3 from Apple to do the reinstall, and I set it up as a new computer to test. I updated to 10.8.4, and that same day, even with a new OS, it started the freezing again for no apparent reason. I am unable to find any logs about crashes from these random freezings.


I have since restored a time machine backup of my 10.8.3 from earlier last week and it is working FLAWLESSLY with all peripherals and has yet to freeze once. I'm not sure why, but 10.8.4 is a MAJOR downgrade for certain Retina Macbook pros as it appears to take them from full stability to barely even usable.


Just curious if anyone has experienced similar issues with their Retinas or otherwise.

MACBOOK PRO (RETINA, 15-INCH,EARLY 2013), OS X Mountain Lion (10.8.4)
