I've got an old Mac-Mini 2012 laying around. It was a gift. I never wanted to switch to Mac on this solid, but not very powerful machine. Over xmas last year I booted the thing, and it was unbearable slow, even with the original version of the OS on it. After an macOS update, it was unusable.
I put an SSD in (thanks YouTube for the guidance) and booted it with Debian and on top of that installed CasaOS (web-based home server OS/UI). Now I can access my music (thanks Navidrome) from on the road (thanks Wireguard).
Docker is still a mystery to me, but I already learned a lot (mapping paths)
Zen Browser (FF) on Win and Firefox on iOS (for sync) works well for me. Edge for all M365 related stuff. Still use Chrome for web dev. Not sure what to move on in that regard...
Is it easier to build a browser for MacOS? Arc was Mac only for the longest time, until they released a crippled Windows version. DuckDuckGo browser started Mac only.
I put that on our website, since I love RSS. We are not a tech company, though, so none of the potential applicants use it. I think some scraper/job boards consume it, but that's it. I built it mainly for fun and to signal virtue :)
