Setting up OctoPrint on MacOS

After initial installation I had error when starting server

error: [Errno 48] Address already in use

Fixed by changing port

octoprint config set server.port 5006 --int

Hmm, can't seem to install octoprint from pip3
Inside the virtualenv, I can successfully install pyobjc
Howeveer when I run:
pip3 install OctoPrint

  note: This error originates from a subprocess, and is likely not a problem with pip.

I am on a mac mini, os 13.1
EDIT: It seems to work if I am not in a virtualenv. I am not sure why, but it seems the virtualenv is using Python 3.9 instead of 3.10...?

That might be because virtualenv just uses the 'default' Python installation on your system - I don't have a Mac to know exactly how it works, but on every other system you have to specify if you want a different version using --python=/path/to/python. None of the core contributors have a Mac as far as I know but I suspect this guide could probably be modernized. In other OS guides, they use venv instead of virtualenv, as it's built in to Python 3 & doesn't have the strange behaviour I mentioned above.

Perhaps if there is anyone out there who would like to improve the guide, it is free to edit for users at TL1 or higher.

Anyone have the correct reboot command to get the octoprint server to reboot?
