I'm new
Mac Mini (late 2012) 2.5 GHz Intel Core i5 4 GB running OS X 10.10.3
I opened System Preferences & Sharing and found the following message to the right of a yellow triangle containing an exclamation point:
"Screen Sharing is currently being controlled by the Remote Management service." It has me spooked! Help...thanks
iPhoto '08, Mac OS X (10.7.4), MacBook used as desktop and laptop.
