View Full Version : iMovie & Quartz Extreme [QUESTION]

Sep 19, 2009, 08:22 AM
I've trolled through Google trying to find the answer, but to no avail, so as a last resort, I decided to bug you guys with this question.

I'm using:

Snow Leopard
ATI Radeon HD 4870 Graphics Card
Apple LED Cinema Display (24" flat panel)

So I'm all up to date...

The other day I was messing around in iMovie (I'm still a novice with this application), and everything was working fine, I managed to edit up a movie, save it and play it.

But to day, when I fired it up I got this pop up window:


In my hunt to find the fault I discovered something called Quartz Extreme Check - 1.2 (http://www.versiontracker.com/dyn/moreinfo/mac/15911) which is a tiny (20Kb) application that checks and displays if Quartz Extreme acceleration is active on a machine.
Tried that out, and I got these pop ups:


I guess my question is, why was it working the other day and not now?
And what can I do to rectify the problem?

Thanks in advance for any help...

Actually, I just reset the PRAM and NVRAM


And the problem has gone away, so Moderators can delete this thread now, please...

Thanks for leaving this thread up. It just saved me. I'm new to Apple products (bought first one three weeks ago) and was starting to get frustrated that an up-to-date MBP with Snow Leopard would all of a sudden not be able to use software that was pre-installed. Again thanks.
