I cannot activate any add-ons on my Mac in Safari preferences.

It is impossible to check the checkboxes on Safari preferences. I am on the admin account.

I am trying to click on those checkboxes on the left, after installing add-ons, but nothing is happening?

MacBook Pro 13", macOS 10.15

Hey justyna666.  I work for 1Password, and we're actively battling this glitch with a number of users. Since it's not specific to 1Password, it's proving hard to find a solution, but one of my colleagues and I might have found one — if you have the problem again, can you go to Safari > Preferences > Extensions, then navigate to a different pane (e.g., Advanced), and then back to Extensions? With any luck, your checkboxes might be enable-able now. Please let me know. 🙂


If you're interested, you can probably break things again, too, and let me know if the solution above works.


  1. Disable your extensions in Safari
  2. Select another Preferences pane (I chose Security)
  3. Quit Safari without closing preferences
  4. Launch Safari.
  5. Open Preferences.
  6. Attempt to enable your extension of choice.

You can't uninstall/reinstall Safari. You have to reinstall the OS to get a fresh version of Safari.


Do a backup, preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart). Run Disk Utility and select First Aid. Then re-install the OS.

sadly, it is still happening, even in safe mode. No other issues (apart from this laptop working very slow and not smooth at all when on safe mode?).

Could it be something with admin settings? It is not a new laptop. Maybe I don't have all the authorizations to perform such tasks? But I was able to log in into my own Apple ID and delete the previous admin account, so I'm guessing I do? Or maybe it's a Safari problem? Is it possible to uninstall it?
