Extensions not installing
I'm trying to re-install the MuseScore Drumline extension but every time I try, it tells me "Cannot import extension on read-only storage: Macintosh HD." I'm running macOS 1.15 (beta 7)

Then your storage is read-only or does not have permissions to access. This is OS-specific and not a fault of MuseScore. Look into the admin settings of your device and see about granting permissions to the affected drive.
I trust you mean MacOS 10.15?

While I agree with everything you've said, I haven't been able to find a workaround or fix for this issue
I tried disabling System Integrity Protection (SIP) and trying to install the extension, I've tried uninstalling MuseScore and reinstalling it, I've tried setting the extensions directory to a "writable, non-rooted" location according to macOS SIP (i.e. the Home folder), I've even completely uninstalled and reinstalled macOS entirely, nothing's worked. Hopefully someone here could help?
And yes, I did mean macOS 10.15, my bad

So it turns out that this was just the fault of the beta os I was using- downgrading from 10.15 to 10.14 fixed the issue
Because of that however, I'm hesitant to update to 10.15 now that it's released.
See @BSG's hint at https://musescore.org/en/node/294996#comment-949773:
The system has to be told to permit MuseScore ... to be allowed to access user parts of the file system, which is surprising at first.

System Preferences -> Security and Privacy -> Privacy-> Files and Folders. Unlock with admin password and navigate to MS3 (correct versions).
Here here - second this. CVannot install or update extensions on Catalina. Have added Musescore to Full Disk access and still no luck.

Or rather #296452: Extensions not Installing in Musescore 3.3 on macOS Catalina
I am also having the same issue. Using MuseScore 3.3.4 on Ubuntu Linux 18.04.
Gives me the same no permissions. Even after giving full rights. And I get a storage is full error as well. But have many many Gb.s available.
Please advise!
