Push notifications deleting after installing Safari 16

Hello shakamar,

Thank you for reaching out in Apple Support Communities. Excellent job with the troubleshooting steps that were performed. To help troubleshoot the notifications in Safari on your Mac, we suggest to perform a restart in safe mode. This helps verify your startup disk, deletes some system caches and more. Once your Mac is in safe mode, please restart it as normal and test the notifications in Safari. This may help resolve your issue.

If needed, here's how to restart a Mac in safe mode:

How to use safe mode

Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Apple silicon

1. Shut down your Mac.

2. Turn on your Mac and continue to press and hold the power button until you see the startup options window.

3. Select your startup disk, then press and hold the Shift key while clicking “Continue in Safe Mode.”

4. Log in to your Mac. You might be asked to log in again.

Intel processor

1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.

2. Release the key when you see the login window, then log in to your Mac. 

3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window.

These steps are outlined here: How to use safe mode on your Mac - Apple Support

Kind regards

Welcome back shakamar,

We recommend testing in a new user account. Here’s the steps as listed: Set up users, guests, and groups on Mac - Apple Support 

• On your Mac, choose Apple menu  > System Preferences, then click Users & Groups .

If the lock at the bottom left is locked , click it to unlock the preference pane.

• Click the Add button  below the list of users.
• Click the New Account pop-up menu, then choose a type of user.
• Enter a full name for the new user. An account name is generated automatically. To use a different account name, enter it now—you can’t change it later.
• Enter a password for the user, then enter it again to verify. Enter a password hint to help the user remember their password.
• Click Create User.
• Depending on the type of user you create, you can also do any of the following:
  • For an administrator, select “Allow user to administer this computer.”
  • For an administrator, select “Allow user to reset a password using Apple ID.”
  • Use Sharing preferences to specify whether the user can share your files and share your screen.

If there’s no issue resolution, please contact Apple Support here: Apple Support

Cheers.
