I;ve had the same issue - to do with Catalyst in the startup items with full screen selected, and then the menu bar is still visible. The only workaround currently is to HIDE finder - easy, but a pain every time....
Haven't managed to learn how yet, but it would be nice to write a small piece of Apple Script to put in startup items, instead of Catalyst, which does the following:
wait 30sec
load catalyst
wait 30 sec
hide finder
if anyone does manage to write this, before I learn how - do post a copy...
I'm having the same trouble (with 3.3) ..
Catalyst is in the osx startup items. When booting the machine and automagically opening catalyst app in fullscreen, the menubar stays.
Any quick workarounds ? (aside from switching to finder and back)
