Quartz Extreme required

I also have this problem and cannot open iMovie '08. I just trashed my iMovie application and have been trying to find a previous version to download but have not had any luck, yet. I think there ought to be a link somewhere to instructions on how to resolve this for those of us without the quartz extreme graphics cards, but no luck there, yet, either. Wouldn't it be nice to just downgrade to a previous version?

That is a very odd problem, and I have it from time to time myself. I was at an Apple store a few weeks ago for an i Movie inservice, and that messaged popped up and trainer was frustrated too. The only thing that I do to get rid of this pest is to shut down and restart, which is fixing the symptom, but not the problem. The trainer at the Apple store went through MacBook Pro and stated that my computer graphic card is compatible with i Movie...so this is not a fix, just a time consuming way around the message, good luck

Hi, Are you on an actual mac or a "hackintosh?" I have seen the error on a osx on x86 machine before. iMovie HD (06) works apparently.

So what exactly is causing this problem? I get the same message too. I think a mac pro should find us a solution besides rebooting the whole OS. I've had my first Mac for 3 months and the OS messes up ALL the time.

PabloRW,

You can find iMovie HD 6 here:

http://www.apple.com/support/downloads/imovieHD6.html

I believe you will have to have iMovie '08 installed on your system in order to install it.

It seems to me your GeForce FX 5200 should support Quartz Extreme.

If you choose About this Mac under the Apple menu then click More Info you'll be able to see if Quartz Extreme is supported.

See "Verifying compatinility with System Profiler" here:

Stan,

Are you saying that you've opened iMovie '08 in the past but no you're getting the error message?

See my reply to PabloRW on how to verify your video cards compatibility.

I had the same problem. I knew it was a configuration problem, not a hardware problem, because other users on the same machine were still able to run iMovie successfully. After poking around I ultimately fixed the problem by going to System Preferences > Displays, and setting Colors to "Millions". Somehow this setting had been changed to "Thousands".

Good move!

I have the same problem. I cant get imovie to work or photo booth. They both say the graphics card does not support quartz extreme. Obviously this is a load of rubbish as it always used to work, and i am running a 12 month old macbook which has core graphics.
I tried different user accounts and the same problem happens in them all. I also tried restarting, clicking on detect displays and changing the display settings away from the high resolution and millions of colours and then put it back again.
Anyone got any other ideas?
Thanks,
Simon.

I've not been able to get iMovie to work since I put in a second video card. I get the message, " Quartz Extreme required.... one or more video cards doesn't support etc.", and then it gives me no option but to quit.

iMovie HD gives me as similar message but allows the option of continuing anyway. When I continue iMovie HD works perfectly.

It doesn't make sense. Two Mac apps doing almost identical things, but one works and the other doesn't. FCE works fine too. What am I missing? Does everyone with more than one video card find out that iMovie should have been deducted from the price of iLife'08?

Thanks for the link! The tip to change to millions of colors got iMovie working, too. I'm grateful for the assistance.

I've got the same issue, only in systemprofile is written 'not supported' but it is a macbook Intel Core 2 Duo so it should be supported. Is it a sofware issue or a hardware? After the error pops up and continue to work with iMovie, it will freeze.

iMovie 06 is available as a free download from Apple here: http://www.apple.com/support/downloads/imovieHD6.html

According to an '07NYT article users were unhappy with iMovie '08 so Apple made the previoius version available. I have both but I like the skimming feature of '08. I wish I could get it to work.
