Is it possible to make a mac program from a windows computer? If so, how?

The instructions on https://love2d.org/wiki/Game_Distribution work just fine on Windows. A .app is treated like a folder on Windows, so you can go in an mess with the files inside. That way, it's almost easier than on a Mac.

The mac .app contains a lot of symlinks, so you have to be careful to preserve them rather than accidentally destroy or resolve them. It's also easy in Windows to accidentally destroy the file permissions necessary for the executable files to run.

Be sure to get someone to test your packaged Mac app for you before you distribute it.

so the distribution page says for windows to do so do I just replace SuperGame.exe with SuperGame.app?

No: https://love2d.org/wiki/Game_Distributi ... pplication

so I've sent the zip to the client, but I have no idea how they're supposed to run it, considering it's a zip.

Zip the SuperGame.app folder (e.g. to SuperGame_osx.zip) and distribute it. Enable the -y flag of zip to keep the symlinks.

I thought the final result should have an executable file name like the mac version of exe.

ok my client sent back this:

anyway I just sent a video of what they needed, so it's all good now.
