Depending on where you end up working, being a Linux admin won’t help much. Not many corporate IT departments support Linux, they’re getting ramped up on Macs now, due to demand…. but hate it. I’ve worked in an enterprise environment for almost 20 years. Pretty much all the Linux admins are using Putty on their standard issue Windows laptop. A couple who are more on the development side have Macs. I’ve saw one guy dual boot about 10 years ago, I’m sure that violated all kinds of policies. One guy has a Linux VM on his Windows machine that he always brags about, but it also doesn’t work with half the stuff he needs for the job.

I know there are some pure Linux shops, and a smaller place might let you pick whatever you want, because they don’t have IT standards and big departments… but mentally prepare for a Windows laptop. There’s WSL on Windows now, but from what I’ve seen with some co-workers, it’s a burden to run. Your mileage may vary.

The Mac seems to be the best way to go in the enterprise, if it’s available and decently supported. It’s Unix, which is nice. But you will run into some issues with different versions of sed, and things like that. I had to install the GNU core-utils on my Mac recently to get something working.
