Hi,
not sure if that also affects others, but for me the Xojo IDE always tries to load 32-bit dylib for my plugins before trying 64-bit one.
I made a feedback case for this: <https://xojo.com/issue/50882>
Maybe Xojo could try to load plugins in this order:
- Mac x86-64
- Mac Cocoa
- Mac Carbon Mach-O Universal
