Perhaps consider looking at the Debian wiki to see whether there’s any advice for thise model and see whether the Mac iso file Debian provides can help you.
Thank you for this, I immediately thought of Don’t Break Debian, when I saw that reply.
This seems more like “more maintainers are needed” rather than “do a better job with package management”.
Also, on Debian I don’t miss anything, for my use-case, everything is there. Except two tools for Linux phones, one of which I recently packaged as my first Debian package (which just entered testing) and another, which I might package.
They’re online already.
