These specific Sierra issues got fixed....

Fixed: Some actions on the main screen respond very slowly when using macOS Sierra (10.12).
Fixed: The Audio Edit window draws very slowly when using macOS Sierra (10.12).
Fixed: The splash screen takes a long time to appear when using macOS Sierra (10.12).


We haven't heard about any specific Sierra issue since that fix.


Have Fun!
