Hi everybody. With MobileMe and back to my Mac, I have no problem personally making the setup work. However, for a client of mine, we are having partial problems with it. She has a brand new iMac and a MacBook Pro, all running the latest Snow Leopard build. From within the office, on Finder, I can discover both computers and launch screen sharing. That way, both the iMac can control the MBP and vice versa. The iMac which sits at the office can also see the MBP when it's at home and screen share. However, other computers like the MBP, once outside of the office, cannot see the iMac and initiate screen sharing. It only works the other way around. Any thoughts? Screen sharing also works no problem with iChat, even if say the MBP is outside of the office and the iMac is in the office.
