System configuration
- Running Sierra (10.12.5)
- MacBook Pro 13" (Early 2015)
Issue
Messages and many other options are missing from the system Share menu, both in Safari and in the Share Menu extensions pane.
These among others are missing:
- Messages (most annoying)
- Vimeo
- Flickr
Here's what I've tried so far with no success:
- Update to latest Sierra 10.12.5
- Run this command line to force-reload launch services
- Disable and re-enable iCloud contacts
- Disable and reenable System Integrity Protection
Related observations
- Under Preferences -> Internet Accounts, I cannot check the box next to 'Share Menu' for Facebook, Twitter, Vimeo etc, even though accounts are correctly configured.
Really appreciate any help!
Update 7/11:
I just got an old 2011 MackBook Pro repaired, and upgraded it from El Capitan to Sierra. The Share menu works as expected, with Messages as an option. Still not working on the machine with the problem.
