FCPX 10.1 Very slow on iMac and lots of spinning beach balls

Grasping at straws here, but you haven't run MacCleaner by any chance, or have any others apps running in the background?

Hi Tom, nope, I've done a completely clean install of mavericks (reformatted the HDD), didn't restore from back-up just moved a few files back, then re-installed FCP, Compressor, plus the latest versions of little snitch and dropbox.(I've tried it without snith and dropbox too and it makes no difference

(I even had my graphic card replaced and a full hadware test done by apple - so it's almost certainly a software/compatibilty issue).

I have also deactivated some not needed FxFactory Plug-Ins, but it did not improve the performance.

But what I have noticed is that Final Cut reloads other events which are not opened, which seems to be very strange and could be one reason for the slow performance. A small windows opens from time to time, telling something like "loading events A,B,C" which are in the library of course, but not opened.

Could this be a kind of preferences setting that other projects are reloded altough those are not currently open?

Changing the magnification of the timeline takes about 10 seconds to change the view and display the thumbmails (3 video layers, one audio layer) which was 2 seconds with 10.0.9. for the same projects.

Not sure what you mean by opening events. Events in a library can't be closed, unless you mean the disclosure triangle.

Maybe I have explained in wrong words. Of course just one project can be open at a time. But what I have seen from time to time is that other events which are not part of the open project in the timeline are "reloaded".

This is the same message what I see when starting FCPX, but it happens during normal cutting procedure also.

Not sure if I am doing something wrong, or if this is bad behaviour of FCPX.

From other's description of the problem, it sounds like FCPX has a memory leak. Classic programming mistake. Editing a 90 minute film, the software crawls....just crawls.

Then again, I find Mavericks unstable, so who knows. I'll eject a device & finder closes and unmounts a connected USB 3.0 drive. This is my first experience with Windows-like conditions on my Mac. 😟 I wonder if the memory compression system in Mavericks is indeed to culprit?

I have just installed Final Cut Pro 10.1.1 on a late model iMac loaded with memory and my Final Cut X is now completely unusable. It took me several minutes just to bring up the About screen to confirm the version. Where is Apple when this stuff happens? Do they not read the forums? I cannot edit video now -- period. Plus with the now silly new file management system they introduced it also lost connections to some clips, so now I have to redo that. I wish Apple would be a little more responsible. Its like the FCP 7 thing all over again. Complete disregard for the end user.

Even with the update 10.1.1'm suffering all the time the program is slow and too much time thinking late leaving my job.

Maybe the newly released update 10.1.4 of the Pro Apps codecs will help?

Fingers crossed!!

I'm going to install now and test.

Installed all the updates, and no difference. This is so frustrating. Editing video is the only reason I switched to a Mac. Now I guess I need to learn Adobe Premier again. At least they don't release updates that make my system in operable. It's not so bad that there is a bug, it's the fact that Apple takes weeks to fix it, and many of us rely on it for business.

Same to me - no improvements with new codecs. The responsiveness is a pain. No fun at all and very hard to get the projects ready for the clients. I tried remove plug-ins, run FCPX exclusevly on the system. I stopped Dropbox, Growl, Adobe Creative Cloud, Skype and some other serveces running in the background - no improvements.

I have no idea what Apple is doing here...

Yes, I've done everything, clean install updates etc and it's just as bad (it's maybe my imagination but possibly it's even worse) I hope someone in the Apple FCP engineering team reads these threads. It's not acceptable. I'm literally losing business because FCP is basically unusable. Looks like I might have to finally open Premiere and learn that instead.

I assume everyone who has had these problems has used feedback to give exact details of this including system details and performance behavior.

Where do you do that? It sounds like a good idea.

I ceratinly have, twice, plus I've spoken to Pro Apps support about it many times who havent been able to help.
