Oh my.

That does not look good.

But . . . this is only when you Restart, not a cold boot? Curious.

Does it happen every time or only occasionally? Only Restart or Start up from Off state?

These are some questions that I would imagine Apple will ask.

I would initiate a ticket with AppleCare support, include the video for their consumption. I would guess "faulty" GPU section diagnosis and unit replacement is in your future.

Sorry. :(

Don't have Apple Care, this is a late 2010 iMac and I didn't purchase any besides the first free year. :(

I tried a cold boot just now and it happend then as well, when I restarted in Windows it didn't occur though, weird.

Might a OS-reinstall help with anything? As I said, the computer works fine apart from this, no weird graphics or anything so I might just have to live with it :/

Oh, it is not new. /$h!+burgers

Uh, yeah, I was tempted to mention that diagnosis might very well include Apple wanting to reinstall the OS.

Yeah, if you've all your data and software dusks in a row, you could try that and see if it provides resolution joy.

Good luck! :)

/in honor of Ray Lewis being in another Superbowl, I'll take a stab at the culprit being a bad IC board that is in the early stages of failure.

While I realize that this question derails the thread . . . .

I'm new to Mac, what exactly is SMC/PRAM?

It sounds as though SMC is analogous to the BIOS on a PC?

. . . . and PRAM is analogous to the CMOS on a PC?
