Did today. Easiest update ever. Two clicks. One on the UIV portal icon and one on an update button. I wish others would adopt this simple an update process.
It opened without any issues. The UI is pretty much the same. it looks like the main changes are to the sophistication of the synthesis engine, but it already did more than I need.
It needs at least OS 10.14, which is where I am, so won’t be long before I have to install a newer OS.
