I recently changed the e-mail address of my Apple ID, but the Find My association on the mac didn't get the memo.
macOS doesn't pull its own weight, at least not in a standard configuration. There are a number of apps that need to be installed. Some of them are free, others are not.
If you're like me, and you're coming from two decades of using Windows and Linux, you might want to keep using the keyboard shortcuts you're used to.
You might also be a programmer. In that case: even better.
