I’ve got an iMac which I do most of my work on because I prefer a desktop. It’s getting quite old (it’s a late 2013 27") but I upgraded the hard drive to an SSD which seemed to give it new life and it serves my needs perfectly as is. However, it’s maxed out at Catalina.
A couple of years ago, I got a macbook air and I’ve stayed at Catalina with it just out of precaution because I share files between the two.
Am I asking for trouble if I upgrade the OS for one and not the other (with RW specifically)?
