Has anyone been able to run MuseScore 3.7 on MacOS?

• Mar 26, 2023 - 07:04

I successfully downloaded MuseScore 3.7. It's an unsigned app so the first step was to registere MuseScore 3.7 as an exception on my Mac, per Apple's instructions.

That allowed me to initiate a launch under MacOS 13.2.1 ... but then MuseScore 3.7 abended.

On reviewing the crash log Jojo noted the missing Qt library ”QtWebEngineCore”. He said it "Might be a bad packaging," but that would be hard to determine, as he doesn't have a Mac.

So I'm wondering: Is anyone successfully in running MuseScore 3.7 on MacOS. If so, how?

One proposed workaround is to launch MuseScore 3.7 from the Terminal command line with -w. That should prevent MuseScore from accessing the web, hence no need for that missing library.) I've tried an failed various ways of launching 3.7 from the command line, without success. Can anyone offer a command that works?

Another proposed workaround is to install Qt 5.15.2 on my system. I’d only want to install Qt if I’m going to start using it—and that seems unlikely anytime soon. All to say, I haven't tried this approach.

On your advice I attempted to start 3.7 by dragging a score onto it provoked the same crash.

I'm in unfamiliar territory with the Terminal but tried that approach.

Don't know if I have the part after \ correct.

    • Need a different file name?
    • Need a space before 3.app?
    • Since the handbook used a capital F I used a capital W:

JBs-mb-5:~ John$ /Applications/MuseScore\3.app/Contents/MacOS/mscore -W

/Applications/MuseScore\ 3.app/Contents/MacOS/mscore -W
dlopen error : dlopen(libjack.0.dylib, 0x0001): tried: 'libjack.0.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibjack.0.dylib' (no such file), '/Applications/MuseScore 3.app/Contents/Frameworks/libjack.0.dylib' (no such file), '/Applications/MuseScore 3.app/Contents/Frameworks/libjack.0.dylib' (no such file), '/usr/lib/libjack.0.dylib' (no such file, not in dyld cache), 'libjack.0.dylib' (no such file), '/usr/lib/libjack.0.dylib' (no such file, not in dyld cache)

Unknown option 'W'.

Then I tried a lowercase -w:

-bash: /Applications/MuseScore3.app/Contents/MacOS/mscore: No such file or directory

Hi Jojo,

Thanks for all this!

I'm only casually familiar with Github. So I'm unclear.

Are you saying there's a pending build, or is there a current build of 3.7 for MacOS that addresses the issue in pull 93? If there's a current build, is there a link to the build zip file at the link you provided? Or can you post a direct link to build file?

It works!!

Just one temporary glitch: Initially there was a prolonged hang at the MS 4 update advertisement dialog. Clicking OK wouldn't dismiss it and I couldn't do anything else. After about 20 seconds that rectified. And thankfully, since the second launch of 3.7 I can immediately dismiss the advertisement.

I was surprised that only the default plugins don't show in the Plugin Manager. 3.7 has its own plugin repository?

Again, thanks for all this Jojo!
