Sierra screensharing not working
I run two MBP' both with 10.12.1 on it. Both are fresh installs.
I can not get screen-sharing to work if the firewall is on. If it is of no problem. I found these instructions, followed them and all worked. I turned both machines of and the next day it does not work again.
