Also worth mentioning Sierra (I believe...) that let you login as root without password.

For me the tooling on MacOS is the only advantage that it offers. I am familiar with it which makes some tasks quite easy and the platform more powerful for me than Windows.

The latter offers alternatives by now and they are quite good as well. Powershell is in parts just a bit more modern than the average Linux shell or you can just install a Linux subsystem to begin with. For me it was a bit late to the party though, but this is one part where Windows really did improve a lot.

But both closed source OS have become worse overall. This isn't some nostalgia the parent hints at, there are certain features that can establish that pretty clearly. From ads to account requirements or thorough suggestions at least.
