[GNC] macOS Sonoma "Gnucash is damaged and can’t be opened" error

[Adrien Monteleone]

I'm suspicious of a missing step.

Did you *install* Gnucash, or just download the .dmg file and open it, 
then click Gnucash.app?

The .dmg file, when opened should have a shortcut to /Applications to 
make it handy to drag the Gnucash.app file over it for installation, and 
even has an arrow prompting you to do so. (you can drag and drop the 
.app file wherever you like in your home folder, but /Applications is 
traditional for all users to have access to it)

Pretty much *all* mac software is installed this way if contained in a 
manually downloaded .dmg. (the App Store does this for you 
automatically, but no, GnuCash is not distributed through the App Store)

Regards,
Adrien
