Q: Safari unable to install any extension
I've about hit my wits end with trying to switch to Safari from Chrome. I'm trying to install a few extensions to Safari, adblock, ghostery, trafficlight, and lastpass.
None of them are installing. I keep getting an error, "Safari is unable to install this extension."
I've tried:
Turning off FileVault
Erasing Keychain node (wasn't one there)
Rebooting into safe mode and attempting install
Rebooting back after safe mode and attempting install
Tried to install direct from developer bypassing extension gallery
Deleting all personal info in Safari
Beyond taking the MacBook into a genius bar, what else can I try?
MacBook, OS X El Capitan (10.11.6)

Sorry for reading your post too fast yesterday. Have you tried creating a new admin account to see if you can install them there?
If you can install them in a new account, try running this program while in your normal account and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor. Please use copy and paste as screen shots can be hard to read. On the screen with Options, please open Options and check the bottom 2 boxes before running. Click “Share Report” button in the toolbar, select “Copy to Clipboard” and then paste into a reply. This will show what is running on your computer. No personal information is shown.
