Apple Event: May 7th at 7 am PT
Hi everyone,
Yesterday I was working on a project on my iMac 27" and everything was ok.
Today I powered up my Mac and the only thing I was able to see was a white background with some black dots on the screen.
How can I fix this problem?
Thank You for your time
David
Assuming that you're running Yosemite, the only OS I've ever seen display that problem, boot into recovery mode, and reinstall the OS. Provide the OS specifics.
27" i7 iMac (Mid 2011) refurb, OS X Yo (10.10), Mavs, ML & SL, G4 450 MP w/10.5 & 9.2.2
Thank You for your answer.
Unfortunately I'm running Snow Leopard. Intel i5, 8 GB RAM, ATI HD6770 1GB.
Since the iMac (27-inch): AMD Radeon 6970M Video Card Replacement Program isn't applicable, then a trip to an Apple repair station is in order.
Thank You very much. Called Apple and they told me to replace the video card.
Thank You Very much.
David
