Distrohopping is just re-installing with a different distro. I don’t why some people switch all the time, I’d consider it a waste of time. Also, I once tried many distros and then settled on one. Sticking with one means you’ll be able to know it very well at some point. I for example opened a lot of bug reports and then even started fixing some packaging, I doubt I’d have gone that far with hopping.

How about: Put Linux on an external SSD in a USB adapter and then swap macOS/Linux SSDs once you’re ready? You could also use a 2nd computer for learning. Take your time and set up things to work for you before deleting your main OS.

Debian, because it has extensive documentation and works really well. If you search for something, you will find a how to. Install the GNOME or KDE flavours, depending on what you prefer. There are also other flavours of course, but considering you want something somewhat familiar coming from macOS, I believe GNOME (+ extensions, perhaps) would work really well for you.
a) privacy friendly and the Debian wiki even lists where Debian could improve b) beginner friendly and especially due to the amount of documentation, also if you need some specific software, it will likely be in the repos c) Debian comes in various flavours, try out a live system or watch some Youtube videos to decide what you like d) works with gaming and there are usually packages for Debian and Debian-based systems

I’ve tried out a Fairphone with /e/os just yesterday. The OS is probably fine, but perhaps also have a look at iode.tech, they are closer to upstream and afaik do security patches quicker. And iodé OS is the next best thing when you don’t want to use a Google device. They support a couple more devices and also something important for security: A locked bootloader. They are based in France. And /e/os collects unique IDs from devices. Ultimately you could get a Fairphone and just try out both. Flash them and play with the UI for a bit. Choose what you like.

Don’t replace your devices as long as they do what you need them to do, an exception would be if you can no longer install security updates, as usually is the case on phones after a while.


Debian has specific installers for Macs, for example.
