itch.io

Solved!  Although MILO can only be played on the itch app, it cannot be FOUND on the itch app.  The solution was to find it on the website, copy the url, then paste it into the app search bar on my Mac.  Now it works and it's fun!  Hope this helps others.

Thanks for trying to solve my problems.   Finally worked something out, which I will leave in an other comment.

Thanks a lot for your detailed response and suggestions!  Unfortunately you speak a language I do not.  I don’t know if you can be more specific or give me advice that would make sense to me or not.  My nephew helped make a game called MILO, and I have downloaded the file to my Macnbook pro but it won’t run, as I said above.  I tried getting the itch app, but the game is mysteriously unfindable on the itch app, so I’m back to the download file from the website, refusing to work.  Perhaps my computer illiteracy is insurmountable, but if there’s anything else you can offer I’d love to hear it!

My MacBook Pro won't run the game I downloaded.  I get the above error message and no info or options.  any ideas would be appreciated!
