I installed PT, X-form and Synthcell, all 2023.3, and tested a few sessions, and all seems well. I didn't time it, but I have impression that sessions load a bit faster - just like, if you just closed one, and open it again, as if its laying ready in RAM, but this is just after PT launch.
Oh well, the beta has been working so well for me that I'm not expecting much difference - I'm
hoping for not much difference.
Maybe the flickering cursor bug… let me check…
…yea, it looks like it's fixed.
(Added: Confirmation in the release notes: "The cursor icon will no longer flicker between different icons on macOS Ventura (PT-294557)".)
