I don't want to switch from my Mac but I might have to.

In general I think you'd be pretty fine. In my work environments, people use different IDE's all the time. I personally use Jetbrains, and I have a lot of colleagues that us VSCode. Never had any problems, unless I was trying to code on their machine and didn't know my shortcuts. Jetbrains Rider for C# seems to have hands down better reviews than Visual Studio and comes with a free educational license. Since you're new to programming, it may be a bit more challenging. You'll probably have to do some basic transfer of figuring out config and functional equivalents from VS Studio, but nothing AI or google couldn't solve. The IDEs essentially all have the same major concepts, with a different GUI and different shortcuts. Plus you'd be ahead of the curve as you'd have to actually understand the IDE concepts and not just following directions line by line. If I were you, I'd do both, setup your code VSCode on your school computers and use it from time to time, just to get the feel for it, and to be on the same reference as your classmates in the event you get stuck, and use Jetbrains on your personal mostly. In terms of education, you'll end up having an even better vantage point of what's out there professionally and understand why Jetbrains is considered a better IDE.
