We have tested the build (reky.app) in 3 different macOS: macOS Sierra, macOS Catalina and OS X El Capitan. In our end and all the testers is working so far. Keep in mind that you have to set your security settings (System Preferences->General) to Allow apps download from: AppStore and identified developers. Also the build is for 64bit macOS as 32bit is deprocated by Apple. If you need more help, can you give us more info about your system? macOS version and machine? Thank you for your intereset in our game.
Okay, I managed to fix it.
So here's the thing, the app after the fix works like a charm, but the issue is that inside the MacOS Application, on /Contents/MacOS/reky, the reky executable DOESN'T have execute permissions, hence, the app fails to open at all. This also occurred to me when downloading another game from itch.io as a direct app instead of a zip, but that's only a suggestion.
So to recreate the bug, download it from the link, and open it, it will say it cannot open. You gotta cd into the MacOS directory inside the Application, and "chmod +x reky" for it to be able to execute. I am unsure how you might patch this bug if it occurs again, just saying. Thank the lords I know UNIX shell...
So, yeah. macOS Catalina 10.15.4, 2015 Mac, 11-inch just in case.
Is this an issue if you are using itch.io app (https://itch.io/app)?
So, this needs some terminal knowledge to understand, so I'll do a quick explanation.
You must go to your terminal, it's an app on MacOS so just search it on the search bar ( duh :-: )
Then, you gotta write:
chmod +x <app-location>/Contents/MacOS/reky
To get the app location into the terminal, you go to the app on finder, then drag the application onto the terminal window, it should be something like /Applications/reky.app for example
So the total command on this example would be:
chmod +x /Applications/reky.app/Contents/MacOS/reky
This is because every Mac application is a folder with contents, and the true executable version of reky is actually hidden inside those folders.
Do take note, this is an example, so remember to put your real path. Also, if the path has a / already, don't add it again. This should fix the issue. You can close the terminal and use it normally. Enjoy :)
edit: Meant for edits341, I'm pretty sure the app creator knows this... or maybe not, just saying.
