[macOS] "MDFourier is damaged and can't be opened"

Question

This issue is caused by the lack of notarization of the app.

On older macOS this wasn't an issue, but unfortunately on newer versions Apple has made the security requirements more strict.

To get around this, please do the following:

Ensure that MDFourier.app (the application downloaded) is in the Applications folder
Open a Terminal and input the following (you can copy paste it):

xattr -rc /Applications/MDFourier.app

and press Enter to execute it.

Now you can close the Terminal app and run MDFourier and it should start correctly
