Can't install extension to Safari

greggarious

I've done all the suggestions - deleting extensions from Safari, deleting folder under Library>Safari, restarting Safari to even restarting computer after all of the above. Still no luck.

Update on this. I tried to install other extensions and I'm getting the same error message

Hello @greggarious,

Here is something worth trying. What we're going to do is reset the entire Safari extension database in the hope that it resolves the issue.

Wiping Safari's extensions

To start make sure Safari is not opened.

Preference plist

1. Open a Finder window and use the keyboard shortcut ⇧⌘G to open a Go to the folder window.
2. Use the following location ~/Library/Preferences/com.apple.Safari.Extensions.plist and click the Go button.
3. Drag the highlighted file to your Trash.

Extension files

1. Like above, open a Finder window and use the keyboard shortcut ⇧⌘G to open a Go to the folder window.
2. Use the following location ~/Library/Safari/Extensions/ and click the Go button.
3. Drag the highlighted folder to your Trash.

Safari Extensions List

1. Launch Keychain Access which you can find in /Applications/Utilities/.
2. Search on the word safari and you should have 3 entries in the results.
3. You want to right click on Safari Extensions List and select the Delete "Safari Extensions List" option.

After all of that reboot your Mac and you'll need to go through the steps of installing your extensions again. With a little luck whatever got messed up was in there and the 1Password extension will now properly load

Let us know how you get along.
