logic pro X CPU is off the chart since Yosemite

I'm having some Logic Pro X issues. The CPU usage is off the charts. CPU shows active when I'm not even playing a track. I have no other applications open. I have repaired permissions etc. It's so bad that the CPU spikes if I play just one track of audio, and Logic will show "system unable to play back.." error. This really is ridiculous. Should I go back to the previous version of OS X? I'm out of ideas. Strangely, somedays it works just fine. As soon as I think the problem has past, it starts up again. I definitely seems like some kind of CPU or memory issue. Any help would be appreciated. I know my system is a little light but I've never had these issues before upgrading to Yosemite. And no, I foolishly don't really use time machine, so that's not an option either.

Thanks,

MikeD

At the moment, Yosemite and LPX is not a recommended combination.... Many people have reported the same behavior of 10.10 and 10.0.7 working fine one day and then it all falls apart the next....

Nothing much you can do as you didn't make backups... which means you can't easily roll back to a previous configuration...

So, your only two choices are

A) Manually backup your personal data/projects/photos/music etc... to an external HD and then wipe your System drive (assuming your recovery partition is still showing 10.9) and reinstall Mavericks from scratch... holding down Cmd + R at startup... Then reinstall LPX plus content plus any 3rd party plugins and libraries you use.

or...

B) Wait for a while (maybe quite a while) until Apple releases fixes for Yosemite and/orLPX to resolve these issues.... and put up with the current problems.

In the meantime, I suggest you start making backups using something like Time Machine or my preferred method which is using the HD cloning utility SuperDuper! as one day, you will need them.....

Not what you wanted to hear I'm sure.. but that's the current state of play.

Wow that's a bitter pill! I guess my frustration with this episode is that Apple designs both the software and hardware surrounding this issue. For them to release a new OS that is so unfriendly with their own software (logic) seems crazy. Who beta tested this? I actually do have a time machine image but it is over a year old. So, I'll probably bite the bullet and just do a re-install of Mavericks. Without a doubt, Yosemite is the worst OS, at least for my needs, released so far. Lesson learned...Apple is slipping. Thanks for your responce.

I would say the users are Apple's new beta test team. They probably use software to test for OS compatibility, seems obvious no one sits down and really puts the software through it's paces on several hardware configurations. Apple's "Pro" market is so tiny compared to where it's at in the iPad, iPhone business it's no longer viable in the same sense it was many years ago. At least they could offer guidelines to a solid working system, like suggesting a clean install of OS will reduce compatibility issues, or has issues with Processor 7.xx on late 2013 iMacs. (Those are NOT real issues btw.)

The fact there hasn't been any Logic-x updates in quite some time may be a good sign these issues are being addressed.

Just as an FYI, I am in the process of reverting back to Mavericks. I am only able to play back a dozen or so tracks with modest amount of plugins under Yosemite.

It's too bad because I personally like the look and feel of Yosemite. I hope the problem is resolved soon for this reason.
