Nauts,
Ive just been transferring a lot of stuff to my MacBook rather than studio pc so I can write tunes while travelling and taking my heat with me as interface and master effects etc… I havnt used OB on my MacBook before and theres a glitch in the OB for heats graphics. See image? Ive tried re-installing OB and same thing…
Well, it is a distortion unit…
Sorry, I’ll let myself out. 
I’ve had similar glitches and I think it’s because of an older OpenGL version… to be glitch free you need version (afaik!) 3.2… and it depends on your MacBook if the graphic card supports that.
The only way you can upgrade open gl on Mac is to upgrade the OS. I’m on high Sierra which is as far as I can go on my MacBook. According to Apple high Sierra is open gl 3.3
This is frustrating
