Hope that helps a bit, and sorry for the wall of text as I'm on mobile. Another thing to keep in mind is dongles/adapters you'll need to invest in some USB-C to A adapters to use your elicenser and soundcard, but again, no problems whatsoever with that. Not sure if those kinds of things bother you but no effect on performance. You HAVE both OS's there, open u Windows and test it and compare with Sierra. Traditionally Cubase has run better on the PC. Cubase is a digital audio workstation (DAW) developed by Steinberg for music and MIDI recording, arranging and editing. I can run 64 or 32 buffers here with Cubase on my Mac, High Sierra using MR816X interface. Also, I've noticed the visual look of crossfades aren't quite as smooth looking as on a PC. I am noticed that Cubase on Serria only go low as 192 in latency. The GUI can be a bit different, I've noticed zooming in/out using the G and H keys (or whatever your preferred shortcut may be) isn't as smooth or quick as on PC. But, as I said, no longer an issue with a recent OS update. You can find more info about it if you're curious through a Google search. There was an issue with some T2 chip that caused audio dropouts but a recent OS update addressed it - it had to do with the machine pinging a server to sync date/time.

I use a 2019 MBP every day at work (recording and editing podcasts) with Cubase Pro 10, I think it runs fine.

Does cubase run better on a mac or a pc
