While trying to figure out why I can no longer screen share with my brother who also has a Mac (whole other issue, "Share Screen" and "Ask to Share Screen" are grayed out on both computers now) I somehow lost my ability to receive iMessages on my MacBook Pro. When I go into Messages account settings, my Google Talk and iMessage accounts are there. When I highlight my iMessage account I see my gmail address (which is my AppleID) and that is checked. Also there is my iCloud address which I don't really use for anything. I used to see my phone number which was checked, and I used to get iMessages to my Mac when my number was there. Can anybody help me get my phone number back into the iMessage account area of Messages? I am running the latest version of everything.
