Because my Mac Pro 2012 cannot get any OS installed beyond Catalina and is has dual Xenon processors MODO DRUM will not upgrade to 1.1.3 or 1.5.0 since it requires a CPU with AVX support or Apple Silicon CPU.
So, while it's all good on my PC, it's a freakin' bummer on Catalina.
Also, I have a similar problem with the latest updates to NI's Massive on Catalina.
So now I sit and wait on a sweet deal for an M1 processor/64-128gb ram/1tb SSD boot drive in a MacPro where I can install my 1tb NVme drive, 8tb samples drive, 4tb projects drive and my 4tb extra data drive.
