Cubase 15.0.6 not working properly mac m4 pro os 26.2

I upgraded from Cubase 14 Pro to Cubase 15 Pro in the hope that the issue would be resolved, but it’s the same if not worse. Constant lagging, stuttering, and glitches, no matter what I do. I also disabled GPU acceleration, and I’m running it in Rosetta mode. Its not workable…

This happened when I updated my OS to 26.2 (Tahoe)

Welcome to the forum!

While I’ve not experienced this, it sounds like something others have experienced, and which some have remedied via a “Mission Control” launch:

Worth a shot. There are other “Mission Control” thread you might search for as well.
