What should I do if i can't open the app
If it says that the program is damaged, its a safety thing by apple. By default, apple only lets you open programs with certificates, but I havent got one. So you should allow it to run any program. Or try downloading it on windows, and then open it on mac.
Other solution: I tested it with the unzip-tool "StuffIt Expander", and it works. (You find it in the App-store)
It said that stuffit is unable to determine the file format
Hm. Ok. I tried it and it worked... then u gotta try allowing to open the apps without certificate...
It just said that the game quit unexpectedly
I really don't know what the issue is... What macOS version do you use?
10.12.6 MacOS Sierra
Thanks for the info. I'll take a look and try to find the issue.
Hm. So I read a lot about the GameMaker engine and its problems, did lots of testing but I cannot find an issue. I used El Capitan for testing and it works fine. Seems like this problem can't be solved properly. I am really sorry.
