You could likely set it up to work "offline" so you can still play your steam games.
If you were to set the steam client to offline (Assumedly through the Mac top bar 'Steam > Offline Mode') it should never need an update or contact with servers to keep working.
That said, I don't know if there is a limit on how long you can have a computer connected to a specific account while never connecting to Valve's servers.
I searched around last night and found out about "offline" mode. And that's probably what I will do come February. Thank you.
