I got a few reports from users that my game's not working on Mac. I don't have a Mac nor do I know anything about Macs. They're getting a Can't open the file because it's "damaged or incomplete" error.

My game is working fine on WinView2 and NW.js. My workflow for Mac export is:

- export to Mac using C3

- remove some array.json files I don't want to share (I do the same with Windows exports)

- remove the first line of c3runtime.js (to not disclose engine specifics). It's a commented line: // Generated by Construct, the game and app creator :: construct.net

- zip everything back up using winzip to a .zip file

Anyone know what may be happening? Can Mac read files created/zipped on Windows?

Thanks

If you extract a macOS export on Windows, it will corrupt it, because Windows doesn't understand essential file permissions that are required on macOS. There's more information in the tutorial Exporting desktop apps with NW.js, under header "Publishing on macOS and Linux". (The same applies for the macOS WKWebView export.)
