Hey folks, so ever since I went from Snow Leopard (10.6.8) to Mountain Lion (10.8.5), I have been getting random CPU spikes. Pretty much what's happening is that at random, my CPU will spike when using Logic Pro X (and Logic Pro 9), and will prevent me from doing anything because the audio will stutter. It doesn't matter how big or small the project is. Increasing the buffer size will help negate the audio stuttering if it's only one instrument, but once I had a few more the same thing happens again.
I'm going to include a screen capture of the issue happening, and then 20 minutes later, I play the exact same thing and the problem completely disappears. This completely blows my mind, and it's impossible to re-create the issue because I don't know what's causing it.
Also, I've noticed that when playing music in general (let's say from iTunes, or from youtube, or soundcloud), and the CPU spikes are happening in Logic, I quickly shut logic down and listened for any audio stuttering. It happens even when Logic isn't open, so this leads me to think that it has to be an OSX issue. I mean, in over 3 years using Snow Leopard, I never had a single CPU issue. Then I wanted to try Logic Pro X and upgraded to Mountain Lion, and that's when the problem started.
If ANYONE has any ideas or suggestions to how I can get closer to finding a solution, I would be very grateful. Is there someone I can contact at Apple? Should I send them this video or something? Anything helps guys, and thanks in advance.
