So that is not quite an issue, just for your informnation. What I did:

From haxorhax/prodatum github page:

MacOS

Update 12/30/22: I was able to verify the github agent build works on Big Sur 11.x and Monterey 12.x OS - with a couple tweaks:

The prodatum-macos-x64 executable needs the .app extension added
Moved the executable to the Applications folder

If clicking gives you an error after that:

The security features may prevent the app from running (unknown company, etc.), so you will need to give the executable permission to run.
Run the following line from a terminal: sudo chmod -R 755 /Applications/prodatum-macos-x64.app
Then System Preferences -> Security & Privacy -> General tab look for a Allow button specific for an unknown application (s/b prodatum-macos-x64.app).
NOTE: Apple M1/M2 chips are not supported by Github currently, with no ETA. The builds in this release are specific to Intel Macs only.

After adding the .app extension and running the above Terminal command, the app runs on my M1 MacMini and on my M1 MacBook Pro in a foder called:
"Prodatum 2.1.2 OSX"
inside the Application folder.

The "README_v2.0.1.txt" coming with the IntelMac version says:

If the directory "prodatum-config" exists in the same directory where
prodatum was launched from (like in this zip file), prodatum will use that
directory to save it's configuration and data.
This is called "portable", as you can move the directory from computer to
computer, without losing your settings and ROM data.

My "prodatum-config" folder in my "Prodatum 2.1.2 OSX" application folder stays empty, so this applies perhaps to the 2.0.1 version only...
