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!!!





iMac, OS X Mountain Lion (10.8.2)
