Color me envious – I wish I were in your boat on both of my Macs. I personally think it would be valuable for those who aren’t experiencing the issue to also report their complete system specs per Fabio’s request in the first post on this thread, so any discrepancies in setup, etc., can be logged.
The count for me at this point is six totally different Macs that I’ve seen the issue on (my trashcan Mac Pro and my 2015 MacBook Pro, a trashcan Mac Pro at Guitar Center, two composing friends one of whom is on a trashcan Mac Pro and the other on a 2016 iMac, and installing it on my girlfriend’s 2017 MacBook Pro). The one Mac out of seven I’ve tried that didn’t have the issue was another composing friend’s 2011 Mac Pro.
