Thanks Alfred, Very informative!

Oh wow! If that is the case then I should have no worries. I'm so used to having to buy either a single use app for one computer only or pay more to use the same app on 2 computers (via a CD). Thank you so much, John Rostron and GaryP

I realise Affinity Photo will work on Big Sur as well as Mojave but I don't know which one to put it on as both computers are very new to me. I have been working on Snow Leopard for more years than I can remember! If I install it on to my Big Sur and find I have problems using it as some have experienced here then would I be able to uninstall it from Big Sur and install it on my Mojave? If so how? or would I need to buy a second Affinity Photo app for my Mojave? I don't really want to buy the software twice but I would like to know which Mac OS to install it on in the first place?

Hello, I have recently bought a refurbished Mac with OS Big Sur and since inherited a Mac OS Mojave. I would like to buy Affinity Photo but I'm not sure which desktop computer to put it on. If I download it on Big Sur and problems arise as explained here will I be able to transfer the App to my Mac OS Mojave?
