This is a very minor point, but I've just noticed that the year of my Macbook Air 2013, under 'About my Mac' has disappeared. It just says Macbook Air. Any idea how to bring it back? PRAM reset has done nothing.
What was the last OS version you saw the year displayed?
Try booting into Safe Mode, login into your your user account and check what About This Mac says. Another thing you could try is booting in Recovery Mode, download the full Catalina OS and apply it on top of your current OS install.

I'm pretty sure it's displayed on this same version, Catalina 10.15.5, until very recently. So no idea what's happened. Like I said not a big deal, just bugging me slightly. Maybe this'll prompt me to do a clean install of the OS when Big Sur comes out - I've never done a clean install on this 7-year old machine!
