I successfully transformed my company from MacOS to Arch on Apple hardware. There are two computers left with Catalina for some specific workflows, in isolation from outside world.

System 76 are cool, but when the time comes we will build custom PCs for work. The "aura" and "coolness" of Apple is gone.

I admit that my decision to use only Apple computers in the office was irrational and tainted by emotional perception from the past. I almost puled the trigger for M1 Air and was planning to upgrade office Macbook Pro's to M1X. Not anymore.

Wow congrats, getting Macs to run Linux sounds a superhuman feat.

No it's really easy, I had Linux running on a 2006 model iMac and I am as far from a Linux expert as you can come.

Ah yes! My understanding is older Macs are easier. The newer T2-enabled Macs make it hard. For example wi-fi, keyboards, and trackpad don't work out of the box, lots of configuration is needed, and some things (ie microphone) simply don't work at all.

Ah ok, makes sense. This was my first mac, things have definitely changed since then...
