Use whatever you are comfortable using. I was forced into working on a PC at a particular firm for a few years, but that’s because their entire system was set up on it. Didn’t stop me from owning Macs at home and spending a few days (excitedly) working from home.
Fortunately, I know work in an office that is 100% Mac.
At the end of the day, though, it’s purely personal preference. If you don’t want to give up your Mac, try figuring out a solution.
