"Staff/Part Properties" window always maximized

  1. Right-click on any staff
  2. Select "Staff/Part Properties"

The "Staff/Part Properties" window always opens fully-maximized (though not officially in full-screen mode).

It used to open as a smaller window.

Even if I resize the window and close it, it will re-open maximized.

I am using the latest MuseScore Mac OS.


I can't reproduce, it could be macOS-specific, but if so, I'm surprised no one else has mentioned it. Have you tried Help / Revert to Factory Settings?

Thanks! I would be glad to try this, but I would like to retain a backup of my custom workspace/palette-- both to save the time rebuilding it, and to help deduce the source of the issue. Is the workspace stored in a file that I can copy or export, then add or import after reverting to factory settings? (I'm comfortable with the command line and with opening package contents on MacOS.)

Yes, the workspaces are in a folder whose location depends on your OS, but it's something like .config on Linux, AppData on Windows, unfortunately I don't know the details on macOS.

Reverting to Factory Settings solved the problem (the Staff/Part properties had always been opening maximized).

I made a backup copy of the following files:

  • ~/Library/Preferences/org.musescore.MuseScore.plist
  • ~/Library/Preferences/org.musescore.MuseScore3.plist
  • ~/Library/Application\ Support/MuseScore/MuseScore3/workspaces/my.workspace

The source of the problem seems to have been the file
* ~/Library/Preferences/org.musescore.MuseScore3.plist
because when I restored the backup copy, the window always opened maximized again.

I was able to restore the workspace file
* ~/Library/Application\ Support/MuseScore/MuseScore3/workspaces/my.workspace
with no trouble.

I guess that covers everything. Thanks for the tips!

I am able to reproduce this problem on my Mac.
At first, the window appears in a normal size. But after you click the Maximize button (the green one) once, the window will always open maximized, even if you resize it back to a smaller size.
I solved this by moving the following files to the trash:


Theoretically, I guess, it should be possible to find the problematic data in those files, so that you can remove just that and keep the rest of your preferences.

Workaround No Yes

Workaround: A) don't click the Maximize button or B) remove (or edit) the preferences files.
I'm not sure whether we can do anything to fix this, or that it's a problem of Qt and/or macOS.

The difference is at the Geometries.EditStaff key in ~/Library/Preferences/org.musescore.MuseScore3.plist.
This is the "bad" version:


And this is the good one:


I copied the data from the good file to the bad file, and that also solved the problem. Entirely deleting this key and the data from the file also worked.
