I recently thought I had to use it, dug up a 15 year old account, because some hardware utility for a mobile Brother printer was only available from the store. After installing the tool it turns out it didn’t even have the function I needed (firmware update of the printer).

That was annoying. And merely having the account signed in also prevented our IT support department from copying my user folder over to the new laptop properly, so we had to do it twice.

Now I’m happily back to not having apple id signed in. (Well… as happy as I can be while still having to use macOS)
