Can anyone point me to a good guide on explaining user IDs on macOS. I know you never want to assign the same UID as a user, but I’d like to get an explanation of how UIDs are assigned by the system and when we go trough the GUI user creation process. I’ll be attempting to create some users via command line and put them into pkgs for creation on other systems and I have to set the the option for UID, but I want to know how UIDs are created so the UID I choose is a reasonable one.
That said, I’m kind of tired of trying to google individual items. It was fine as a hobbyist, but now that this is my job, the lack of formal training is really becoming a problem. I’d like to locate some kind of course or textbook or systemic training regimen to go through so that my overall ability to troubleshoot and deploy in a timely manner increases.
…I’m a social studies teacher who, with no formal training in IT, no certifications, and only volunteer and hobbyist experience, has become the “mac person” in an ICT department in a component of the biggest bureaucracy on Earth.
