A exported preset or bank should be able to be used on both systems.
I don't know if other preset files can be used on both systems. It's actually a good question. Can the preset files that i on windows have in programData be used on a Mac?
I guess the .fil extension that's used in Windows for a preset file in ProgramData is a database object, and that it's the same on a Mac. But i don't know.
I hope Arturia tell.
