Game not Running on Mac (but ONLY when downloaded...)

[Eike]

Hi! Quick question - my game isn't running on Mac, and I have absoutely no idea why. I have Windows, but I've been playing around with it on a Mac to get to the bottom of this... The interesting thing is that when I physically transfer the .rar to Mac using a memory stick, the game runs absolutely fine, but when it's downloaded off the internet (i.e. how I get my game out to players), it says 'The application "[game name]" can't be opened.' (with an image of the Finder icon.) Likewise, other players who downloaded it and tried to run it on Mac cannot.

I've tried several different builds of the game. I've tried storing/downloading them from Mediafire, Dropbox, Megaupload... and always, that error. Whereas, when I put the EXACT SAME files on a memory stick, they work perfectly. I'm very confused! Is there any precedent for this? Does anyone have any idea what's going on? (I'd like to release my game to a lot more people than I currently have, but I'm having to keep it very low-key until I've figured out what's gone wrong with Macs...)

I'm guessing it has to do with unpacking and repacking the zip file. That's not supported, since it loses permissions information. Give them the original .zip file, and things will likely work.

Oh! Yes!! That's it. Had unzipped to delete the .rpy files, but have realised that can be done while it's still zipped. Thank you so much!
