After installing 3.3 (not 3.2 like the reported version says) I tried to install the MDL extension and it keeps saying "Cannot import extension on read-only storage: Macintosh HD."
Fix version
3.3.3
Comments
See https://musescore.org/en/node/296375 - this seems to be an issue with how some Catalina systems are configured, if I'm reading that correctly.

All Catalina systems. The new security features aren't optional.
I am having the same issue

I've downloaded MuseScore 3.3 and when I try to open it on my Mac (Catalina operating system), it says:
“MuseScore 3.3” can’t be opened because Apple cannot check it for malicious software.
This software needs to be updated. Contact the developer for more information."
Help?

This is "similar" behavior as earlier macOS versions, just different wording. Slightly off topic from this Issue Tracker thread, but relevant to macOS Catalina.
Use this process to launch the app: https://support.apple.com/en-us/HT202491
Skip down to the part that says: "How to open an app that hasn’t been notarized or is from an unidentified developer"

Who's in charge of MDL? Are the sources "ours"/instructions for building/testing?
The souces are on github, see https://github.com/musescore/mdl
