I’ll admit that I’m new to the game here. Have a 2011 Mac Mini that’s been running 10.15.2 really well, but just ran into an issue where new software won’t install unless it’s been updated to 10.15.3. Do you have any suggestions for finding more specific instructions on updating to 10.15.3? I downloaded the update package, but am not sure where to go from here. I just keep getting the error that the system is not supported. Thanks!! 🙂

Have had audio problems since updating, sounds glitchy when using logic pro and occasionally throws up an error saying bitrate mismatch.
Anyone else had this problem or know how to fix it?

I am on 10.15.1 with no sound issues in the latest Logic Pro X 10.5. My Dac is a Steinberg UR 44. However I’d really appreciate a Guide for the 10.15.5 update since I am unable to update from 10.15.1.
