I'm trying to install MuseScore 3.4.2.25137 on a 2011 13 inch MacBook Pro running macOS 10.15.4 Catalina. After going through the installation process, I click on it for the first time and it says: " MuseScore 3 can't be opened because Apple cannot check it for malicious software ".

See #296799: MuseScore 3.3 can't be opened in macOS 10.15 Catalina for the simple workaround; this will be fixed in the next update.
