Signal keeps crashing on MacOS after recent Sequoia update

[thomasdn]

Using a supported version?

• I have searched searched open and closed issues for duplicates.
• I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

After my recent update of macOS to the Sequoia version, Signal worked initially but shortly after the macOS update, Signal received an update as well. After this update Signal crashes immediately when I try to start it.

I just get the "Signal quit unexpectedly" message and the option to send a crash report.

I am not sure what details in the crash report are safe to post here. I do not want to risk exposing any sensitive data like keys, etc. that might compromise my Signal security or that could be used to identify me.

The error is curious: CODESIGNING 4 Launch Constraint Violation. What happens if you go to https://signal.org/download and install Signal Desktop again? Does that fix things? Does it then start happening when it auto-updates?

Please consider reaching out to [email protected] so you can feel confident sharing more information!

I had the exact same behavior as described above; I tried trashing the app, reinstalling from https://signal.org/download, and it fixed things for me!

I'll keep an eye out for the next time it auto-updates to see if it breaks again

Reinstalling the app from a new download also seemed to fix the issue on my system.
However, I think there clearly seems to be a bug since multiple people end up in this situation...

[scottnonnenberg-signal]

Please let us know if the behavior comes back!

I unintentionally created a duplicate issue: #7047

It happens when Signal is being updated using the auto-update feature. The Signal-App version from the website works fine.

I just got the first auto-update since I reinstalled from website last week, and this auto-update did not break anything. Seems to have been something leftover about the old version we were on that Sequoia did not like when it updated 🤷🏼

I've had the issue of Signal breaking on auto-update several times since upgrading to Sequoia. Downloading from signal.org has restored Signal.app, but subsequent auto-updates have reintroduced the error of Signal not launching.
Locating the app in Finder, the last modified date of all files are set to Dec. 31st 2097 at 11:00PM.

I don't have evidence if this also happened on the previous fails.

I've been seeing this behavior since upgrading to MacOS 15 (Sequoia) as well.

I've worked around the issue for the last several updates by manually downloading and installing the latest version from signal.org. But this is a less than satisfying experience. Report has been submitted to Apple as well.

This was helpful. Going and changing all the signal files in the .app to the current time/date fixed signal for me without reinstalling.
