FOR MAC USERS WITH THE "APPLICATION CAN'T BE OPENED ERROR" I'm not a developer by any means but I got the same error and this is how I fixed it:

- If you unarchived the zip file with the default Archive Utility MacOs app, you will most likely get this error. I don't know exactly why, but a quick google search for the error found that you might get this error due to the way the app decompresses (?) the app file.

- Decompress the app using another unarchiver app. I used The Unarchiver and got the app to work. Currently using it now on MacOs Catalina.

Hopefully this helps someone!

I tried the Unarchiver, but it said it cannot be opened because the developer cannot be verified. macOS cannot verify that this app is free from malware. The Unarchiver created this file on an unknown date.

The only 2 options I have is to "move to trash" or "cancel".

Can you open the app? Thanks

You can try going into your security settings and toggle the "open anyway" option, or something similar to that. AFAIK Catalina automatically stops unsigned apps from opening but gives the option to open anyway through the Settings app.

The developer cannot be verified is usually a settings issue. By default macs now only like to run apps they know of. Go here and type.in the terminal command listed to disable this feature. I've been supporting Macs in a professional environment for 17 years. This will. Ot hurt your machine. There used to be radial button options to allow from Any, but Apple got rid of that as a default option. This will allow you to install any app without question.

Something else I know about itchio apps on Mac is that they tend to prefer being run from the itchio app. Which is kinda like Steam client but for itchio. Get it and run the app through it on it mac and you should be all good.

See my comment above; for Catalina, the only thing that worked for me was to chmod the executable.
