I checked that I installed all the SoundFont, tried all of the https://musescore.org/en/node/96811, none of them works: gave my MS3 all the disk permission, reverted to the factory setting, reinstalled MS3 and soundfonts, Restarted the Audio and MIDI Devices, reset the PRAM/NVRAM like the link suggested, my computer does not have touch bar, i really don't know what else i can do here to make it works. So plz help me! Thanks

Anything new on this ? I had some hope for a fix, as ONE TIME (!) i launched Musescore and had everything working.. Then I checked, I had the same version as before... So it seems to randomly work, but one time on like more than 200 launches..

Type Functional Graphical (UI)
Reported version 3.3 3.5

I started having this problem this morning. Yesterday it worked. I have tried resetting to factory defaults, restarting the audio engine and installing the latest version and updating the soundfont file. From reading another thread I entered these commands:

$ /Applications/MuseScore\ 3.app/Contents/MacOS/mscore -F
dlopen error : dlopen(libjack.0.dylib, 1): image not found
dlopen error : dlopen(/usr/local/lib/libjack.0.dylib, 1): image not found
$ /Applications/MuseScore\ 2.app/Contents/MacOS/mscore -F
-bash: /Applications/MuseScore 2.app/Contents/MacOS/mscore: No such file or directory

I am running macOS Catalina 10.15.6.

I am still getting the problem. It is intermittent. Some days it appears and some days it doesn't. Sometimes resetting the NVRAM helps and sometimes it doesn't.

At the moment it does not work. When I run MuseScore by opening a file I get the following error in the system console.

xpcproxy[810]: libcoreservices: _dirhelper_userdir: 557: bootstrap_look_up returned (ipc/send) invalid destination port

Close and restart , the next error message.
xpcproxy[926]: libcoreservices: _dirhelper_userdir: 557: bootstrap_look_up returned (ipc/send) invalid destination port

If I open MuseScore with no open file there is no message. But then when I create a new empty score this error:

xpcproxy[1274]: libcoreservices: _dirhelper_userdir: 557: bootstrap_look_up returned (ipc/send) invalid destination port

to add: following this error, musescore immediately crashes on attempting to open. hence is unusable. this seems to be 100% reproducible, and happens not only w musescore 3.5 but also musescore 3. doesn'tr hapen with musescore 2.3.2. (but that older version won't open scores I had previously been working on in later versions, so I'm a bit flummoxed at the moment.)

I want to make sure you have tried starting MuseScore from the command line using the -F (capital F) to start MuseScore. If so, explain what happens when you start MuseScore normally.

mh ? What don’t you get ?
The issue has something to do with Handling portaudio under Catalina yeah.
It’s the only one of all my music software that hasn’t passed the update correctly, I’m not gonna try downgrading and thus having to reinstall/reconfigure 150Gb+ of software/VSTs/etc.. for one small soft.
Is it clearer ?
Now if you don’t have anything that can help me on working around this issue, don’t bother writing on this thread ty ;)
