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

I finally received my new 27" iMac today and installed all the latest updates and then the latest versions of FCPX and compressor.


Spec of new iMac:


27" Late 2012

3.4Ghz Intel i7

8GB RAM (I also added 16GB of third party RAM to the machine to take it up to 24GB RAM but remove this later)

GeForce GTX 680MX 2048MB Graphics card

1.12TB Fusion Drive (1.09TB free)

OS X 10.8.2 Mountain Lion


Immediately I noticed performance issues and then it kept freezing whilst running FCPX - the whole OS would freeze resulting in me having to actually turn off the machine and turn it on again. It happened repeatedly so have done all the obvious things but still have the issue.


So far I've tried (with no luck):


- removing the third party RAM

- restarting the computer, multiple times

- making sure everything is up to date

- removing the FCPX preferences

- doing a PRAM and SMC reset

- fully uninstalling and reinstalling FCPX

- running the short and long Apple Hardware Tests (no problems found)


I am working with a large quantity of video files off an 8TB Thunderbolt drive but I've been using FCPX on my old 27" iMac and had no problems with that at all, the spec of that being far less powerful:


27" mid 2011

3.4Ghz Intel i7

8GB Ram

Radeon HD 6970M 1024MB

1TB hard drive


I'm thinking it could possibly be the graphics card or a software issue?


Any help or advice would be great!!!


Thanks!

I've heard nothing since the 13th Feb which was when I was told that if the iMac team got an update from the FCPX team, they'd let me know. Since I've not heard anything since, I have to assume that the FCPX team have not even provided the iMac team with an ETA - or at least, not one which they feel able to commit to publicly.


My best guess is that this issue has exposed a more fundamental problem which is endemic in FCPX and which they're having difficulty re-engineering the whole app to avoid, especially as they will have already been working on new code internally. They are probably also feeling that they'll need to have some "new feature" to announce along with any changes to address this issue to avoid it looking like it's only a patch for poor code...not that I'm cynical about how Apple deal with publicity about any flaws in their products at all based on previous experience with other bugs I've tried getting resolved in iOS etc where they've still refused to acknowledge that the problems I'd been having had been due to any flaw, hoping I'd just accept that the issue "magically" stopped after an iOS update.

Same exact issue here


27" imac i7 with 680MX graphics and 32GB memory.


you can recreate the bug at will by using the "pixie dust" title. Definatly a hardware issue.


spoke with apple tech support last week and no fix or ETA for fix available


sad considering i waited 1 month for this "top of the line" computer and it cannot be used for the one application i need it for , Final cut pro X.



now can anyone confirm that this issue will not happen with the 675MX graphic? i might downgrade in order to get work done!
