10.0.8 and mvericks??

Sorry I cant find this topic discussed in the forum but is FCPx 10.0.8 compatibel with OSX Mavericks??

Yes.

Thanks, I've heard never to download a new osx mid project but it's very necessary that I do so right now, why is this, what issues can I expect?

At our production company here in Denmark we simultaneously updated two machines running FCPX 10.0.9 to Mavericks. This was in November. Basically we updated OSX to see how FCPX would perform. And yes, Mavericks was compatible with 10.0.9. But in the weeks following we experienced so many OSX crashes when editing in FCPX - that we simply decided to roll back OSX to Mountain Lion.

Only when FCPX 10.1 was released in December we updated to Mavericks.

And on some machines we even waited until 10.1.1 came out in January before updating with a clean install of Mavericks and a clean download of the 10.1.1. app. We are seeing the best performances in FCPX on these machines.

So maybe you shouldn't update to Mavericks mid-project. I don't have experience with Mavericks/FCPX 10.0.8 - only 10.0.9 but that wasn't a lovely day. Maybe you should wait?

What makes upgrading the OS "necessary"?
