Final Cut Pro X freezing on top spec new 27" iMac, help!

But no crash? Just spinning beach ball or complete lock up with frozen mouse?

Did you use feedback?

Complete lock up! Screen freezes. Cursor doesn't move. Nothing works. Hard reboot is the only way to start over. All changes made to te title are kept intact, even if it was in the middle of rendering.

I have called Apple Care twice, and have done everything that they've said. Can you give me a link to feedback?

The link is on the FCP menu.

So the question remains, is it the specific graphics card with the iMac's or are people with different video cards having the freezes as I suspect and it is the software itself. I would love for people to respond who don't have the 680 mx.

My card is the GTX 680MX 2048 MB...

I too had the problem not sure why it hasn't occurred since maybe I haven't messed with titles enough(ill try that later) but it did crash identical to what people are describing twice I ended up trashing my preferences as stopped working off of the external drive

I have an i7, 8gb ram, 680mx, fusion drive

post your specs and crash criteria

3.7 I7

32 G 1600 MHz

680 MX 2048

OS X 10.8.2

3T Hard Drive (2.5 T free)

Shouldn't freeze. Freezes when editing titles (mostly) in FCPX.

I contacted Apple Care about the same problem with a brand new iMac i7 16GB 1TB fusion GTX680 - I got refered to the iMac product specialist at first, who initially assured me that my suspicion that it might be an incompatability with the GFX card was unfounded and that the web site for FCPX hw needs not including that card was just an oversight, but then he went and did some more checking and instead said he'd need to refer it to the FCPX engineers in the states - took a full diagnostic dump to be analysed etc and I'm currently waiting to hear back.

NB this is a new machine which I can make crash the OS fairly reliably simply by creating a new project in Motion and trying to render it, or by performing some fairly simple steps in FCPX. The machine has passed all the Apple HW tests, the HDD passed it's tests and other than problems when FCPX/Motion try to do rendering, everything behaves itself. (it's only certain things in Motion/FCPX which seem to cause problems. If I avoid then, it runs like a dream!)

It /could/ be the fusion drive, but until I hear otherwise, the fact that the GTX680 isn't listed as being compatable with FCPX is making me think that Apple have "sold me a pig in a poke" 😟

The graphics card is most likely not listed because it's not been tested.

I'm glad that this topic is receiving attention. I hope that Apple comes up with a solution soon.

Alright, I guess I'll jump in on this as well...

I also picked up a new 27" iMac, 16GB, 680mx, 1tb fusion. FCPX freezes on me everytime I pull in the 'Pixie Dust' title. As soon as it starts to render, it freezes. Hard re-boot required. I have tried many other titles and I have not seen the issue. It seems to only be happening with 'Pixie Dust' so far. I have not tried changing font colours or transforming yet - I'll try that next, but for now it looks like we are all having the same/similar issues. I really have no clue what it is. I suspected a bug in the program at first, but now I am more inclined to believe a hardware issue like the graphics card is the culprit. I have scoured (and posted on) many other forums and have found many others with the same issues - nobody has found a resolution or even an acknowledgement from Apple that there is a problem.

Hopefully someone figures this out soon. I'm quite dissappointed as I also picked up this machine for video editing and did not expect to see these kind of issues considering the money spent.

At least I now know I'm not alone.

Ok, just went back and tried of few of these things (changed font colour, size, transformed) - none of these actions caused a problem for me. Once again, for me it's just a render issue with 'Pixie Dust'. I can live with that. Hopefully there are not other issue lurking that are yet to be discovered.

So I just talked to the Apple Care Support and was forwarded to someone who knew our "problem"

He told me that this is a particular problem of all graphic cards with 2GB ram and that it would be "under investigation" at the moment.

It actually sounded like I was not the first person talking to him about this particular problem.

However, he was pretty confident that the only solution is an update of FCPX.

Of course he didn't know how long this can take.

Pretty depressing...

Thanks NewMacForMe - the Pixie Dust title does seem to be a reliable way to reproduce the issue, which I've been able to confirm back to the support person dealing with my case.

By the way - in a lot of testing, I've found that SOMETIMES, if I'm lucky, if I find FCPX starts to "stutter", if I can get the focus away from it by switching to finder or bringing up CMD+ALT+Esc quickly, then keep doing anything to prevent FCPX carry on for a few seconds, when I switch back, it can finish what it was having problems with and avoid a complete lock up. This only seems to work if I catch it quickly, and if the bit it's having trouble with is quite short, but it might just save someone losing some work if it works for you.

The Apple Care person dealing with my enquiry has said:

"Last night they [FCPX engineers] confirmed the the article [the one listing HW compatible with FCPX] would be updated soon and the GTC 680MX [sic] would be added to the list.

They did not say if an update would be released before then.

For now it seems it should be compatible but case has not been closed."

and he asked me to provide details of how to reliably reproduce the crash, hence the thanks at the start as using Pixie Dust means it is reliably crashable using entirely Apple supplied content in a trivial project, which I suspect will be a big help to the FCPX engineer getting to the bottom of this. *fingers crossed*

Wow, finally an acknowledgement from Apple! Great, let's hope for an update soon! Glad in some small way I could help.

I too have the same problem:

My new iMac with FCPX crashes when rendering complex templates and crashes when exporting with Motion 5

Using Motion 5.0.6 and Final Cut Pro X 10.0.7 on New iMac (December 2012) Mountain Lion,

During the rendering of complex FCPX mac crashes and I have to force a restart.

I also happens when I try to export movies with Motion 5.

Does anyone have the same problem with my new iMac?

iMac, OS X Mountain Lion (10.8.2)
