Audio Glitches In Music Playback

I just installed Kodi 17.3 on my Mac Mini and am having audio glitches when I play music at the same time I check my email or use Safari etc. It seems to be related to CPU usage, but I’m not sure. I tried lowering the resample quality and that seemed to help but the problem still exists. Any thoughts?

Here’s the link to a debug file HTTPS://PASTE.UBUNTU.COM/24818381/
I’m running OS X 12.10.4, with a 2.4 GHz Intel Core 2 Duo and 8GB of RAM

Thanks,
