Upgraded Mac, Software Issues - GIMP, KRITA & CC3+

Back at the root of the problem. I don't understand why a 32 bit software can't work on a 64 bit system. The problem should be the opposite.
Maybe Macs are different but on PC, we got many 32 bit programs still running. Although most of these are small and would not benefit being coded in 64 bit.
Even if 32 bit Photoshop is not optimal, it should work.

I think you're misunderstanding something. 32-Bit software does, of course, run just fine under 64-bit Windows. It's just that 32-bit software cannot address and use many of the resources of a 64-bit system.

Correct. There's no need to write smaller 32-bit programs into 64-bit code. They don't need and usually wouldn't use the full resources of a 32-bit system. But large graphical programs like the cartographic applications that I named would perform much better if they had access to memory over 4 GB and the other resources that a 64-bit system has to offer,
