MacOS - MuseScore "is damaged can't be opened"

Issue type

Crash or freeze

Bug description

For months I've been running v3.7.0.4524440406 on Mac OS Ventura 13.3.1

macOS 10.16, Arch.: x86_64, MuseScore version (64-bit): 3.7.0.4524440406, revision: github-musescore-musescore-f3d36a3

I'll start by saying I'm deeply appreciative of all the work dedicated to making 3.7 exist!

Today I tried to install the latest version but got the error that MuseScore "is damaged can't be opened"

After that I downloaded a revision a few versions back, but I got the same alert with 44930:

Any special steps required to get beyond this?

Is this perhaps related to the unsigned issue which I overcame when first opening v40406?

Thanks!

Might have been caused by the forced move to a newer macOS build system and XCode.

xattr -c /path/to/MuseScore.app

It might work this way.
This is a not good way from a security point of view, but I think it works as a workaround in this situation.

Reported as fixed in https://musescore.org/en/node/342126#comment-1194631 after xattr -c /path/to/MuseScore.app

@scorster can you re-check?

[scorster]

Sure, I'll see if it works.

What's the direct link for the current MuseScore 3.7 MacOS download?

Hi Jojo,

I don't entirely know my way around this neighborhood, but I downloaded "MuseScore 3.7.0.5378956140 Devel"

I get the same "damaged" alert as posted at the start of this thread.

Hmm, pity...

Even after that xattr -c /path/to/MuseScore.app?

[RickyRister]

Also ran into the same issue. The xattr fix worked.

[Jojo-Schmitz]

Does the artifact from #93 work? It uses Qt 5.9

[RickyRister]

No difference.

[Jojo-Schmitz]

So it doesn't depend on the Qt version used.

But the xattr still works, right?

What about the PR artifacts (for Mu4) on the upstream repo, they are not notarized either (only the nighly builds are), do they work regardless? Or do they need that xattr too?

I wonder whether I can make that xattr part of the build process.
Hmm, no:

When an application gets downloaded from any source other than those that Apple seems suited, the application gets an extended attribute "com.apple.Quarantine". This triggers the message: " is damaged and can't be opened. You should move it to the Bin."

So it needs to be done on the target machine, after the download and install.

But the xattr still works, right?

Yeah, xattr still works in letting me open the app. The playback is still greyed out and unusable.

downloaded this artifact https://github.com/musescore/MuseScore/actions/runs/7718288564

I'm getting “MuseScore 4.3.0.240302229 Devel” cannot be opened because the developer cannot be verified. instead of the quarantine message when I try to open it, which is the expected message to get when downloading apps from the internet. I bypass it as normal by right clicking open. The app works (The sound isn't broken or anything).

tl;dr: it works as expected

Yeah, maybe notarization isn't the cause after all.

[Jojo-Schmitz]

#294 doesn't solve this, as I can't notarize.
