Unexpected Logic popping/crackling fix


I just came across this thread after troubleshooting a similar popping + crackling issue in Logic Pro X. I had to sign up to Gearslutz just to share my (unexpected) fix.

Quitting out of Google Chrome solved it for me!

A bit of background - I'm running MacOS Mohave on a 2015 Macbook pro (quad core i7 cpu + 16GB ram), and was experiencing frustrating popping + crackling in Logic Pro X whenever playing / recording any VST, even though CPU usage was showing really low. I tried all sorts of audio and buffer settings with no luck.

As a test, I quit out of everything running on my system, re-opening things one by one. To my complete surprise, Google Chrome was the culprit. As soon as I closed Chrome my pops and crackles in Logic disappeared completely. If I re-opened Chrome, they'd come right back.

As another test, I then loaded a bunch of tabs in Firefox, to see if the issue wasn't just specific to Chrome, and the crackling doesn't appear in Logic at all. It's just when I'm running Chrome.

Anyways, just wanted to share my experience, in case it might help.

Hope you can solve it, good luck!
