Creating an older installer on a newer Mac
So I just upgraded to a new MacBook Pro M2. And I mistakenly erased the HD on my older MacBook Pro (late 2013) that was running BigSur without first creating a new installer (I know, not my best moment) . And no, it did not have a recovery drive set up either. Disk utility is now happy to help as soon as I tell it where the installation is coming from.
I tried downloading an installer on the newer MacBook Pro but it won't work and says it cannot be installed on the new one. My question, is it possible to create an installer from the newer computer, purchase one somewhere, or is the old computer bricked now? It has still been working great and I hate to see it go to waste.
