MacOS Catalina: Slow by Design?

I am using Ubuntu 20.04 on a Thinkpad X1 Extreme Gen2 and you would be surprised how "normal" it feels as a development machine. Sure there some little annoyances, the touchpad behaves a little worse than on windows, sound is a little worse. But the most important things, Keyboard and Screen are excellent. The system in general does not feel like the horror stories that people keep telling about linux on desktop(notebook). Now that WSL2 is getting Cuda even windows looks workable. Their new terminal app is amazing. After a decade of Mac notebooks it was quite liberating and I would not switch back even if the flaws in macOS would be fixed. It is for sure the nicest of the big 3 operating systems but for development work Ubuntu is hard to beat for me. YMMV but it won't hurt to look around you what else is there.

I've been seeing the trajectory of Windows (pre-2012 or so) -> Mac (2012 - ~2019 or so) -> Linux (~2018 - now) play out with quite a few people without any issues.

And I don't mean developers. They're all pretty educated people but it's taken me by surprise. They come to me in frustration over Mac, they don't want to return to Windows and they really, really, really want linux. I've been using linux since about 1997 so they come to me. I usually push back, thinking "do you really want a unix workstation?!" but they insist.

My strategy has been some x2xx lenovo (like x230 or so) for about $300 from ebay, 8/16gb of ram or so with an SSD, the extended battery pack, putting mint on it and then just handing it over. Everyone, much to my continued surprise, has loved it and are really happy with it.

It's happened 4 times now and I'm still shocked every time. They've told me they use youtube to figure things out.

They're fine with libreoffice, gimp does what they need, supposedly spotify works on it fine, they don't know what bash or the kernel is and it's all fine. Incredible.

I recently _really_ tried adopting Linux on a hobby development machine that I built back in 2016 (hardly new hardware -- and desktop not laptop). Sleep never worked, graphics sometimes borked, UI felt janky and inconsistent, icons are super fugly and often too theme-y to the point of being undifferentiated at a glance, HiDPI support is a giant mixed bag (in 2020), machine would randomly freeze (mostly elementOS; Ubuntu didn't freeze as much), Hauppage drivers rarely worked consistently and often required reboots, I hated the mouse acceleration curves and was horrified to learn they were effectively hardcoded in X (I'm not talking just speed which is tweakable), gstreamer was nightmare to develop for, the Ubuntu & elementaryOS stores are a joke, and the mix of apt/snap/nix was very frustrating and the opposite of user-friendly.

I switched back to my 2012 MBP and it's predictably gone well since, plus I get iMessage integration with my iPhone.

YMMV
