That's not a very fair comparison. And while I'm sure MacOS isn't exactly cheap I never encountered a situation where I had to use some piece of software that required me to run MacOS. For what it's worth I was mainly thinking of the Linux/BSDs that I actually want to use when given the choice It's free forever, easily customizable to fit my various needs, from embedded barebones application to media server to workstation. I actually own and control the OS (my debian doesn't upgrade to a new version behind my back) and I can even dig into the code if I want to. I'd sooner give 100 euros to the FreeBSD fountation than 10 euros to MS frankly. I gave them enough money indirectly already with all these prebuilt computers I've bought in the past decades which came with Windows preinstalled, only for me to immediately wipe them with something else.
