So, I took the lunge (despite being only 6 days out of the free upgrade period )
Upgrade installed on MacBook Pro running OSX 10.11.2 with Cubase 8.5 running along side 8.0.30. And it locks at the splash screen showing “VST2.x → MPC” then closes. If I then open 8.0.30 it works fine. Now, I know that 8.0.30 is currently not compatible with OSX 10.11.2 according to the Steinberg website, however it works. And that Cubase 8.5 is supposed to be compatible, however it isn’t for me.
The frustration is that I also upgraded on my W10 desktop - no issues.
Anyone else with the same issue?
