what is back to my mac in icloud
Back to My Mac. Back to My Mac is a feature introduced with Mac OS X Leopard (10.5) that uses Wide-Area Bonjour to securely discover services across the Internet and automatically configure ad hoc, on-demand, point-to-point encrypted connections between computers using IPsec. It requires users to have iCloud set up, as well as an Apple ID. Due to its generality, Back to My Mac can work for many Bonjour-enabled services, not just Screen Sharing (similar to Apple Remote Desktop) and File Sharing.
