My suggestion would be to reframe your thesis. Rather than consuming content, change your perspective to one where you are appreciating art.
The world is vast and full of amazing things, you don’t need to feel like you’re wasting time when you dedicate that time to appreciating art that you love. There are books, games, movies, short form video essays, podcasts, and all sorts of things that are real expressions of the human experience from different angles, which is what art is, and there’s nothing wrong with appreciating that art, learning something from it, and growing your understanding.
Unless you’re harming yourself or others by enjoying the art you enjoy, just keep on doing it.
That said, if you really want something else, gaming is (IMO) a great way to spend some time, tabletop or video. Learning a programming language is another one and can lead to very fulfilling paths where you can make things that you enjoy and easily share them with others.
I’ve dabbled with Linux on Mac hardware a couple of times and I’ve got to say that Linux DEs generally hew closer to Windows conventions than Mac ones and I found using the Mac keyboard with Linux to be a dreadful experience without the fact that the chiclet keyboards are the worst shit I’ve ever put my fingers on.
I very quickly snagged a standard mechanical qwerty 104 key with brown switches and cursed every moment that I had to use that abominable keyboard built into the stupid MacBook. Apple seems determined to do things different for the sake of different as much as they possibly can and trying to adapt all their nonsense to the Win/Lin way of doing things made my life worse in numerous ways (most DEs have great remapping for keys and such, but it gets messy fast if you’ve got apps from different paradigms.)
I’d very much recommend against going out of your way to get a Mac keyboard for using Linux unless you enjoy fighting against things. But hey, if that’s your kink, then a Mac keyboard with Linux would be my recommended way to go.
