A Macbook Pro 2016 user here (MacOS and EndeavourOS dual boot)
KDE: some menu options freeze, can’t change keyboard layout
Me: slow transition towards i3wm, write some basic scripts to get what I want working
it took it like 7 months to finally have issue: dbus timeouts when launching some applications
Reinstalled and it works. Well has some issues, like audio and wifi take effort to get working.
Also I find Flatpaks a headache to work with. Easy to set up, but I would consider it rather messy.
I still kinda use MacOS. Would I recommend? Yes, but under specific circumstances. You may need to buy some software. I can get what I want with Homebrew (unless you –no-quarantine it verifies the apps after each update). Is kinda plug and play system when going from Apple to Apple, but in terms of customizability and functionality Linux is superior. Also newer MacOS is awful when it comes to storage. I don’t even know how it is possible for it to take so much space with it magical bits I don’t need neither want and can’t delete. Also get your wallet ready, since older Apple products lose support and you can’t simply upgrade your OS (technically can with some effort), so you can buy a new Mac. And I can tell you that it sometimes gets annoying when you can’t install things just because OS version. MacOS is not meant for much gaming neither for people that want to use it for development, it is possible, but harder thanks to its dir structure. Also it is harder to make MacOS builds and get proper scaling on retina displays (some apps get blurry). Also Mojave is the last OS version to support 32 bit (rip gaming). No Steam Proton. And you can’t just disable external monitors unless you unplug them (great for my modular setup with more than one machine and one monitor), which I find really inconvenient. The monitor is multi input but my notebook is stil outputting to that damn display and prefers it for launching applications on there. Meaning I can’t work on it without either this pain or disconnecting it with one utility I found that has an issue on github that you can’t reconnect the monitor unless you reboot. Also why can’t I set a 60Hz monitor to 60Hz and 30Hz is the maximum? (can do on Linux with no issue)
And did I mention I tried to run Krita on my MBP and it sounds like a jet? Yea, performance is sometimes great on weaker MacOS devices
So yes, go buy that awersone Apple computer, but don’t expect it to work flawlessly. There’s plenty of little details that in the end mess up your day and user experience.
I mean, if you have money for the newest Msomething macs then sure buy one, but if you want to buy older, look for those that can run Linux with decent hardware support, or you’ll regret your purchase.
