Thank you

1 - 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.

2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading 

3 - Does the issue present in this mode ??

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

5 - 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.

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

7 - Download the Application Etrecheck directly from the Developer.

This is a Diagnostic Tool that makes no changes to the computer.

It makes a coherent and readable inventory of both the Hardware and Software used on the computer 

The application is free or paid from added features.

More than one Web Browser installed and used on this machine ?

Under normal circumstances , even if, say Google Chrome or FF were set as the Default Browser, hyperlinks in e-mails would either present an Error code 10673 or open in Safari.

Suggestion - in the e-mail wit the Hyperlink - Right click the Hyperlink which would present a Sub Menu. What are the option presented.

see below image

Change the Default Browser from ?? to Safari

Great work 👍

The Old, restart often times fixes many issue.

The Seasons Best to you and family 🇨🇦
