My iPhone and iMac both share calendars. My MBP USED to share the same calendar. Now it just keeps everything to itself!

I'm not liking this anti-social behavior. I've double checked everything. Any ideas?

I am guessing you use iCloud. Have you tried signing in and out of iCloud in System Preferences. It also is possible your password expired for your Apple ID.
