I think most of the gripes described are really issues that come from moving from a MacOS desktop to try a Linux desktop; if you were moving from a x86 Linux desktop to the Pi the experience would have been much less painful.

You are stating in step #2 that the Pi4 cannot output 4k at 60Hz. Could you please insert a footnote that it actually can?

I meant everything that runs on x86 Linux. Of course iMovie and Adobe stuff doesn't work, lol.
