File this bit of advice under “public service” from this blog!
There’s a new update to the macOS operating system. It’s for version 10.13 or High Sierra.
I read about it this morning in this post from Sophos.
Crazy but true – Apple’s “show hint” button reveals your actual password
It’s an interesting read (and a bit technical) and the wisdom is at the bottom of the document.
The technical details from Apple is available here.
While it’s always a good idea to apply patches when they become available, this is particularly good advice if you fall into one of the cases described in the Sophos article.
Just a heads up. It’s not a small upgrade and will require a reboot of your computer. But, this small inconvenience will make your computer safer.
