Compatibility issues with MacNetPlayer on an M1 Mac might be due to the software not being updated or optimized for Apple's ARM-based architecture. You may want to check if there is an updated version of the software that supports M1 Macs, or try running the app using Apple's Rosetta 2, which emulates Intel-based apps on M1 chips. If issues persist, contacting the software developer for support might be necessary.
