can I upgrade from macOS High Sierra running on my Mac to macOS Mojave?
Tried that and got an alert box : This copy of the Install macOS Mojave application is damaged, and can‘t be used to install macOS.
I'm thinking that my Mac is too old (it's an iMac (27-inch, Late 2013))???
If it's a 2012 or newer model, or a 2010 desktop Mac Pro upgraded with a Metal-capable graphics card, yes. Otherwise, no.

Delete "Install macOS Mojave" from the Applications folder then download again while in Safe Mode.
It's a 2013 model, but I don't see how to do the upgrade?
