You’re thinking of iOS. That doesn’t apply to the Mac.

Yes it does. I had a USB Image of the OS X Installer I created some years ago. Was not able to install it (since the certificate expired). I had to reset the Systemclock to something like 2015.

But I guess they don't expire like iOS updates do.

That was due to a separate bug related to code signing. The poster above you who got downvoted was correct.
How is it a bug that a certificate expires? Every certificate expires at one point and if you try to use in the future it will not work as it is expired. That is not a bug. It is a feature.
iOS requires permission from Apple, so resetting the clock doesn’t work.
