Since the build depends on the GitHub build infrastructure, you need a quite recent macOS version. This is currently macOS 13 for Intel and macOS 14 for ARM based Macs. It might work down to macOS 11 but I cannot test that.
Macos will complain about different things when you try to run the application:
- The application is unsafe to run since it is downloaded from the internet
- The application is unsafe to run since it is not signed by Apple
Note: You might also get alternatively a totally confusing error that the application files are corrupted. This is the same issue.
To fix it open the Terminal app and enter the application folder:
cd /Applications/ConvertWithMoss.app
Then remove the evil flag (Requires your administrator password):
sudo xattr -rc .
Since this seems not to work for everybody, there is another solution:
Temporarily, disable the Gatekeeper with
sudo spctl --master-disable
Open the application (should work now). Close it and enable Gatekeeper again to feel safe...
sudo spctl --master-enable
The application should now run also with Gatekeeper enabled.
- Run the application again and click away the error.
- Now open the system settings and go to Privacy & Security Settings.
- At the very end, there should now be a message saying something like 'publisher of ConvertWithMoss could not be identified'.
- Click on the allow anyway button
- When you start ConvertWithMoss again you need to click away another 1000 dialogs but then it works.
Finally, have fun.
