Except that Apple breaks audio applications with every new release of macOS and has for years. And, it's just a matter of time before Apple kills basically every DAW and VST when they finally kill off OpenGL on macOS.
Edit: What I have said is true here, so I'm unsure why the downvotes.
Curious, why would OpenGL break VSTs? (And yes, I get that AU is the preferred way over VST2 or even VST3, which is why most modern plugins are available in AU as well. I just don't see how OpenGL plays into this.)
I learned this running them on Windows in a VM. I would have expected it to fall back to software rendering like the old days, but no. I ended up installing some build of Mesa for Windows.
