OK, mothership computer wants a MacOS update, I have my first cup of coffee, may as well get it out of the way so it doesn't come back to bite me half way through something important later, like when I'm midway through running a script to pull 100k records from an API (I have the most exciting days).
So I install the update. Takes about five minutes. All good, the version number has incremented. Start to write an email.
YOUR COMPUTER WILL RESTART IN FIVE MINUTES! screams the mothership installed IT nobbler. I just did that, says I.
So 33 minutes later and one incomplete email, I'm still staring at a progress bar. Sigh.
