In addition to tutorial material promoted inside Musescore, MuseGroup, the managing company of the MuseScore project maintains an online server https://musescore.org for the musician community free of charge. The community volunteers to maintain written handbooks and a collection of help pages collaboratively. To ask for help, use https://musescore.org/en/forum
Everyone are invited to join the community and encouraged to contribute, see https://musescore.org/en/donate and https://musescore.org/en/contribute . Report bugs of Musescore 4 the windows, macOS and linux software at https://github.com/musescore/MuseScore/issues
There are other really good quality third party tutorial materials, video streams and communities for different level of Musescore users online, most notably https://school.masteringmusescore.com/ created by Mr. Marc Sabatella. While Marc Sabatella has been contributing heavily to MuseScore codebase and official tutorial materials and diligently helping the community for an extended period of time, that site is not affiliated with Muse Group or any of its subsidiary companies.
[the following is a work in progress, please add missing info]
Resetting Musescore app preferences may be necessary if your app's preferences are corrupted. This deletes custom palettes and custom keyboard shortcuts, and clears out links to recent scores under File menu and Home tab : Scores but will not delete any score files.
Feel free to consult volunteers at https://musescore.org/en/forum before committing. Proceed at your own discretion, Muse Group and the online community are not responsible for any data loss.
If MuseScore does not start, you must run this process via the Command line.

C:\Program Files\MuseScore 4\bin\MuseScore4.exe
or
%ProgramFiles%\MuseScore 4\bin\MuseScore4.exe
For the Windows Store version (Windows 10), it is pretty well hidden, search for it via Windows Explorer
After a few seconds, MuseScore should start and all the settings reverted to "factory settings".
For advanced users,
The main preference file is located at:
C:\Users\[USERNAME]\AppData\Roaming\MuseScore\MuseScore4.ini
or
%APPDATA%\MuseScore\MuseScore4.ini
The recent list is located at:
C:\Users\[USERNAME]\AppData\Local\MuseScore\MuseScore4\recent_files.json
or
%LOCALAPPDATA%\MuseScore\MuseScore4\recent_files.json
The other preferences (palettes, session, shortcuts, workspaces, logs, ...) are in:
C:\Users\[USERNAME]\AppData\Local\MuseScore\MuseScore4\
or
%LOCALAPPDATA%\MuseScore\MuseScore4\
For the Windows Store version (Windows 10), these are pretty well hidden, search for them via Windows Explorer
Instruction written under this section (macOS) is not tested and no Musescore 4 specific macOS test result found online yet (October 2023), the following is adapated from Musescore 3 https://musescore.org/en/handbook/3/revert-factory-settings. Please test it, correct errors, and remove this paragraph.
/Applications/MuseScore\ 4.app/Contents/MacOS/mscore -F
This resets all MuseScore preferences to factory settings and immediately launches the MuseScore application. Note that you cannot quit the Terminal without quitting MuseScore. You can safely quit MuseScore, quit the Terminal, and then reopen MuseScore in the normal fashion, ready to continue using.
For advanced users, the main MuseScore preference file is located at ~/Library/Preferences/org.musescore.MuseScore4.plist
. Often, deleting this file has no effect: macOS stores a cached copy of the settings in some unknown location. The correct way to delete this file, is by running the following command in the Terminal app:
defaults delete org.musescore.MuseScore4
The other preferences (palettes, session, shortcuts, workspaces, logs,...) (Those are not cached by macOS.) are in
~/Library/Application\ Support/MuseScore/MuseScore4/
source : https://musescore.org/en/node/345932
The following is true for Ubuntu, and most likely all other Linux distributions and UNIX-style operating systems.
mscore -F
Or
musescore -F
Or
mscore4portable -F
Or, if you are using the AppImage version, use the cd
command to change directory to wherever you saved the AppImage. For example, if you saved it to your Desktop (and there is only one):
cd ~/Desktop
./MuseScore*.AppImage -F
This resets all MuseScore preferences to factory settings and immediately launches the MuseScore application. You can now quit Terminal, and continue using MuseScore.
For advanced users,
the main MuseScore preference file is located at
${XDG_CONFIG_HOME:-~/.config}/MuseScore/MuseScore4.ini
The other preferences (palettes, session, shortcuts, workspaces,logs, …) are in
${XDG_DATA_HOME:-~/.local/share}/MuseScore/MuseScore4/
