Idk How I missed that Thanks for telling me about the tag!
I will look into how to make it work in macOS but since I don't own any macOS device plus im new (barely 2 months in) and also solo for now, So no promises when it will be done. >.<
[PS Yep Totally I had the same thought, after I made it I was like wait a minute...!! Then thought about it but went with it anyway cuz Kirby's cute.]
I'm not actually sure if the Windows Unity Editor can build a macOS version. Apple might have some requirements like to sign the app it must be built from a mac or something. Anyway you can check in the Hub. Open Unity Hub app > Installs > Click on the specific install version you used to make this game > Click the 3 dots in the upper right corner of that install > Select the macOS build support files > Reopen the Unity Editor > Open Build Settings Window > Choose Windows, macOS, Linux Standalone but change the target to macOS > Build
