Mac OS Big Sur 11.7.10 with WhatsApp Desktop 2.25.1.83 problem. Application failed to start "4" error

I'm not responsible if you break or damage your macOS installation or machine. This is for "advanced"users.

Hi, I have the same issue, looks like it's happening on Intel-based Macs. I think they messed something in the code. I tried reaching WhatsApp support to submit the issue but their support system is awful, it opens a chat on WhatsApp, managed by AI, that doesn't work when the issue is not related with the topics on the list. You can't also submit screenshots or any logs. Can't even talk to a real person to explain further...

I am also on Monterery 12.7.6 and WhatsApp has been working fine. Now it stopped working and installing old versions just force you to download the latest version.

Neither App Store or the WhatsApp website download version of latest app seem to work.

I get a crash report including:

Termination Reason: Namespace SIGNAL, Code 4 Illegal instruction: 4

WhatsApp is sooooooo buggy.😔

I have the same problem with MocOS Monterey - does anyone know how to fix this?

I am running macOS 11.7.10 Big Sur.and have the very same issue.

It makes no sense to reinstall the old version bc this is outdated.

Further I have uninstalled and re installed Whatsapp with the same result: Code 4 illegal instruction

I have asked Whatsapp-help to check.

They asked my telephone number and that was the end of the customer help.

The app works very well on my iPhone and in Safari but the desktop prog refuses to open.

Has anyone an idea of a workaround?

I uninstalled all parts of the program with AppCleaner (great free app). Installing old versions only FORCES you to upgrade to the latest, which does not work.

The minimum requirements (macOS 11) have not changed. Therefore we can only WAIT until they fix this buggy app and release a new version. And just hope it works.😱😭😰

Please everyone report the bug to WhatsApp on X.com as we can't us the in app bug report system!!!🤬

Hello, I have the same problem (Whatsapp 2.25.1.83 on Mac OS 11.7.10)

As the app forces you to update to the latest version, we can only wait for WhatsApp to fix the app! They don't even have their forum. Terrible buggy app.

On the iPhone it works well but the desktop refuses to open

Yes, we are only talking about macOS version here. 😉

I also posted to WhatsApp on Twitter/X

as it’s also broken on Monterey, I guess they have raise the minimum requirements without letting us know. Really nice, WhatsApp.

I had the same problem with 25.2.83 but on my iPhone. As soon as I updated WhatsApp it started crashing on opening. I suspect the issue might have something to do with iCloud, as what finally fixed it was disabling whatapp in “sync to iCloud”. (After 3 days of trying everything under the sun)
