Can't start MuseScore 4 on Mac
I was using MU 4 for a long time without any problems on x86_64 mac. Last time I opened without problems is April 23, 2023. When trying to open MU 4 I only see the splash screen for a split second and MU 4 won't start.
I removed MU 4 compltely (musescore/v4.2.0/MuseScore-4.2.0.233521125.dmg) and re-installed -- Same problem
Removed again and tried latest nightly (musescore-nightlies/macos/4x/nightly/MuseScoreNightly-latest-master-x86_64.dmg) -- Same result
MU 3 (OS: macOS 10.16, Arch.: x86_64, MuseScore version (64-bit): 3.6.2.548020600, revision: 3224f34) works as expected.
I don't know how to debug this, so any handle on this is appreciated.

Perhaps going back to 4.1 or 4.0.2 could work for you?
Does the following help?
1. Open Finder
2. Press Cmd+Shift+G
3. Type
/usr/local/liband press the Return key4. Find the file
libMuseSamplerCoreLib.dyliband move it to trash (possibly you need to enter your password).Be sure to touch only that file and nothing else :)
This file is the MuseSampler library, which is a part of Muse Sounds. It might be causing this problem, but deleting it is the only way to find that out.

This worked! Bad that MuseScore does not report this or auto fix it..
Thanks a lot

This worked for me too. But how do I get my sound libraries back? I had strings and choir - according to the MuseHUB I still got them, because I can't download them again. I also downloaded the keys-library, but I can't find that either. Please help :)
Edit: I find my libraries in Finder, but they have no location, as I obviuosly deleted the file. How do I get the sounds back into MuseScore?
Edit 2: My OS: Big Sur v. 11.7.10

To get the sound libraries back, simply open Muse Hub > Settings > Check for updates. The Muse Sampler will be reinstalled silently in the background. Relaunch MuseScore Studio and go to Diagnostic > Muse Sampler > Check Muse Sampler to see which version is installed.
If MuseScore Studio crashes again, you'll need to delete the library again and wait for a future update to the Muse Sampler to fix the problem.

That seems to be the fix and the problem. If I delete the Muse Sampler .dylib file (or, for safe keeping, rename it with a different extension), I can launch MuseScore, but will not have the Muse Sampler libraries ("Muse Sample library is not found" is the message I get when I check Muse Sampler). When I next open Muse Hub, a new .dylib file is created, and once again I can no longer launch MuseScore.
I restored the .dylib file from a backup, and once again I can run MuseScore with the Muse Sampler libraries (v. 0.51, according to the diagnostic). So I have to be careful to never open Muse Hub until this gets fixed.

You need v0.6x

A patched version was just released -- can you try again with Muse Hub and see if the issue is resolved? Sorry for the inconvenience!

I followed your reciepe, but there was no update availible. So, when I go to Diagnostic > Muse Sampler > Check Muse Sampler, I get the message "Muse Sample library is not found". Does this mean I just have to wait for a Muse Hub update?

same problem with me: it is not possible to open muse studio to open diagnostic.
Is there any chance to get the fix soon? My work is related on some of the muse sounds...

Can you retry now? A patched version of the MuseSampler was just released. You'll need to start Muse Hub to allow it to find and download this, and then start MuseScore again.

Wait—you got muse sounds and muse hub on macOS 10.16. Catalina? Oh wait, I see. What OS version did you open it in? 11? Sorry for the necropost, I know it’s fixed, but I’m wondering if this can help someone else.
I can’t start MuseScore 4 on my Mac, and it’s really frustrating. I’m starting to think the problem might be a virus on my computer. Maybe something is blocking the app from running properly. It’s a reminder that keeping your device safe is so important. I’m planning to check for viruses and install better protection to avoid issues like this in the future.

Don’t worry too much; most likely, the cause is a Qt bug that apparently affects a tiny fraction of users. It’s fixed in a newer Qt version, but we can’t use that because it causes other problems. However as soon as we can fix those other problems, we’ll update Qt which should fix your problem. I understand it’s very frustrating though; and your frustration is our frustration, so to speak.
