OpenSUSE on Desktop, macOS for laptop. I’ve used macOS on portables for years now but only in the last 3ish months have I gone the linux Desktop.
As to the “why” - macOS because it’s polished, tightly integrated with the hardware, the ecosystem works harmoniously, it’s secure and Unix-based (Darwin is the name of the base OS used for both macOS and iOS).
For Desktop - I used Windows pretty much all my life but it’s gradually turned into a bloated advertising and tracking engine. I’m speaking as a home user and a 10+ year IT professional. Linux has come in leaps and bounds and OpenSUSE is an enterprise-grade OS that also happens to run games and other personal things nicely. If I wasn’t using it I’d probably be using Red Hat but I dumped it largely due to their shitty business practices.
MS have always been a little shitty and I don’t want to sound “high horse”-y since everything is flawed in one way or another, but basically:
the creep of advertising into the OS (despite charging for a license for Windows)
the substantial telemetry/metric and analytic collection of the user activity
the installation of so much unwanted garbage (e.g. candy crush, tik tok, etc)
the use of its user base as “beta testers” by pushing half-baked features
the removal of features
I understand that they’re running a business and that they can’t support old OS’ forever and can’t appease every user, but the above was more than enough for me to jump ship.
Edit: sorry I realised after replying you meant red hat lol, @[email protected] said exactly what I was referring to. For those looking for an alternative, Rocky OS is the new CentOS and is built by its original creator.
