Hi there !

My WhatsApp not opening since I have updated to Sonoma software.

How can I solve this problem ?

Please let me know.

Thanks.

With the Third Party Application 100 % Closed

Hold the SHIFT key and try to launch the application from the Applications folder ( Not Dock )

This is a Safe Launch of the application

Still issues >>

Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.

Safe Mode will also eliminate Third Party Software, extensions and drivers from loading. It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 

Does the issue present in this mode ?

Sometimes a Safe Boot followed by a Normal Boot will just put things right.

Still issues >>>

Check with the Developers of this Application or updates, upGrades or additional support

It is their responsibilities to Support their Software.

To make it work on the version of macOS it is intended to used on

Welcome

Good work there 👍 updating the existing version of WhatsApp

Usually that will fix many issues ( updating )
