Lost access to all websites

Hi all,

On 10.15.7, MBP16" I cannot access ant websites apart from Apple and iCloud.

That's on any browser, not just Safari.

Safari: can't establish secure connection.

Chrome: The connection was reset.

Apple and iCloud take quite a while to load, but once loaded they run quickly.

The WIFI is confirmed in order (another MBP + 2 iPhones), so it's clearly a software issue of some sort.


Any brilliant ideas?

MacBook Pro 16″, macOS 10.15

—Reboot ?


To trouble shoot further you can:


—Try a SafeBoot https://support.apple.com/en-us/HT201262


also: https://support.apple.com/guide/mac-help/start-up-your-mac-in-safe-mode-mh21245/11.0/mac/11.0


Takes noticeable longer to get to the login screen, does a 5 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.

Login and test. Reboot as normal. Caches get rebuilt automatically.


In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.


This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.



—Test issue in another user (or guest user) account https://support.apple.com/guide/mac-help/set-up-other-users-on-your-mac-mtusr001/mac

This will tell you if it a universal issue or isolated to your user/admin account.
