support for older macs

on mac os, you need a new machine to use TM, the alternate method is to use the PWA. Because alternate web "app" version constantly fails to save a license and the api keys, it would be nice to have a functioning option that works on a mac that isn't brand new. so the "idea" is to either make the mac app work on macs that aren't brand new, or to create a better method to store & retain the PWA/web app's api & license keys a different way that makes it persistent. Don't get me wrong, it's super fun to start each session of TM by going through the awful lemon squeezy licensing process of guessing which of my identically-named device activations to deactivate & reactiviate, then add all of the keys back into the web app whenever I want to use TM. But would be cool if at least one of the two "mac" options was actually functional for people that don't have the newest versions & mac silicon.
