You don’t need an apple account to use a Mac. If you just want to enter a username and set a password, that’s all you need to do. If you want everything synced between another Mac or iPhone and so on, sign into iCloud. But you don’t HAVE to, just skip it.
I thought this was going to be an American joke about automatics, but then realised that this is like when I explained to younger colleagues that I just drove my car home ‘crash gearbox style’ when the clutch failed, some were amazed that it was even possible. (Match the revs and feel the gear mesh) Edited to add: when I first tried linux on a pc with CRT monitor, to get a gui going I had to roll my own modeline. Bzzt, oh not that value, ctrl-c try another one. Such funsies
