I see several threads that report freezing in certain situations. This seems to be the closest match for my issue. My iMac seems to completely freeze at random times, but when I’m doing the same action. During playback if I use the smart mouse to scroll left or right the audio continues to play, but the computer completely becomes unresponsive. I have to power it down to recover. This doesn’t happen every time I am scrolling, but it happens often. I have also had the system completely freeze when dragging an audio file into a new track. Again, it doesn’t happen every time, but it happens very often. Last night I finally had an issue that causes the freeze that I could repeat almost consistently. The system froze 7 out of 8 times doing theses actions:
drag track form trash to audio folder
drag that track into the project
I’ve been blaming everything except Cubase prior to this issue. I read of some weird Bluetooth issues for my 2015 iMac, so I stopped using the magic mouse and disabled Bluetooth. I have reinstalled Cubase completely. I have disabled third party plugins. Still random freezing.
Another weird issue is when I recover from the freeze, sometimes my first launch of Cubase Pro 10.5 actually launches Cubase Artist. I’ve never installed Cubase Artist. When I shutdown Artist and re-launch Cubase, it is always correct on re-launch.
I also have Cubase Pro 10 installed. I have not had any issues with Cubase Pro 10.
By the way, there is never a crash log after the freeze.
I should add that I did not have this issue prior to Catalina. I held off on updating to Catalina until July. I thought that would be plenty of time to work out the bugs for all of my software, not just Cubase.
Here’s my setup:
2015 27" iMac 32GB RAM w/ external Thunderbolt LG ultra-wide 34" Monitor
Mac OS 10.15.6
Cubase 10.5.20 BUILD 179
Magic Mouse 2 / Wired keyboard
