I was using my Mac over the weekend when I decided to change the song on iTunes from the Today Extension in the sidebar. I swiped to bring the sidebar into view and
Hmm... not there (also no Weather, etc.) OK, I'll open up the Edit interface and
ok, nothing there either. I'll just open up "Extensions" in System Preferences and turn things on
Nothing there either (there should be a fourth entry on the left hand side for "Today Extensions")
I have a second machine at work that doesn't have these problems. Both on the same version of El Capitan.
In the interest of full disclosure I am running El Capitan 10.11.1 beta 3 because I didn't opt out of beta updates to the GM quickly enough (was on beta 1 when I first noticed) but like I said my work machine is on the same version/beta and doesn't have these issues. And I was on beta 1 for days before I noticed.
Any idea what I can do to get my extensions back?
(also, my Time Machine backup outgrew my hard drive so rolling back isn't an easy option)
