Not sure whats going on the screen completely freezes. Sometimes when im watching a video on youtube the screen freezes but you can still hear sound. Ive also had it where a video freezes and so does the sound. It also happens when playing games.

When I say it freezes I mean the whole screen is frozen. There is no beach ball or anything its just frozen the mouse doesnt move or anything. It does this for a minute or so.

Ive tried resetting the smc and it works for a day and then it freezes again. Ive tried shutting it down and turning it on. I dont want to do a fresh install of osx as it will be a pain to re install all my programs.

Anyone know what the issue is and has it happened to them ?

See if the Console Logs show anything after it freezes.... Console is located in the Application Folder > Utilities > Console.app

I have the same issue with a mbp late 2011. I read that it is meant to be related to USB issues but I have not got anything attached.

The MBP loses internet connection and then starts to freeze up while the the dreaded pinwheel appears. Then nothing works leaving me no choice but to hard restart. Its happening very regularly.. 10 times a day at least

Can anyone clarify?

imac freezes ati 2600 WORKAROUND

Imac 24" mid 2007, mavericks- freezing again after memory increase
did all the "updates"- no succes or "is not required for this computer" message


now "solved" by keeping itunes open, minimalized
not elegant, but works
suspect it keeps the video card busy, so it not falls of its rocks
has not frozen since

Those GPU's were notorious for freezing when released. Apple kept throwing firmware updates at it until the issue was resolved to their satisfaction.
