Unable to select "Share Menu" for Mail, Photos, Facebook etc
Hi all,
I am trying to select "Share Menu" for my accounts - at the moment, I am unable to use the Share button to email images from Photos, but also unable to share via Facebook et al.
When I go to Internet Accounts in System Preferences, I have the choice to select "Share Menu", but when I try to click the check box, a tick flickers, but doesn't stay there.
Very strange, and oh so frustrating.
Running iMac mid 2011 with El Capitan v10.11, also Mail v9.0, Photos v 1.1.
Please help me?! I am happy to answer more questions to get to the bottom of this.
Thanks
iMac, OS X El Capitan (10.11)
