This video is to show the problem I am having with my 27 inch iMac.


I have a 27 inch iMac (Mid 2010)
Processor 2.93 GHz Intel Core i7
Memory 12 GB 1333 MHz DDR3
Graphics ATI Radeon HD 5750 1024 MB
Software OS X 10.8.4

I am going to try to do the bios flash thing, but this is very frustrating.

Just like the rest of you, I am having artifacts come up and about 3 or four mins, lock up with nothing but the cursor moving around. (clock froze and nothting is clickable.)

Usually i start up Lightroom and after about 5 mins the madness starts.

I mean with this much attention I hope that they are working on a fix.
