Safari freezing and apps crashing after macOS 15.6.1 on Mac mini M4

Safari freeze when trying to write in a login page, any web site. All my software programs no longer open. They start but then suddenly quit. Some programs seem to have lost their licenses.

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 ?


If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.


If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.


To avoid a session of Q&A, Q&A  and Q&A  


Download the Application Etrecheck  ( External Link ) directly from the Developer.


The Application is Not a " Silver Bullet "  and is  only a tool to examine the Hardware / Software used on this computer
