Hi. I use an iMac 24 inch, 4GB RAM, the latest Leopard 10.5.4. I would like to connect to two machines for friends: 1. One is a Mac Book Pro. This connection would be from mac to mac, so I hope this is easy? A google search for remote desktop etc keeps bringing up the RDC from Mactopia (Microsoft). Is it possible to connect between two macs that are not on the same LAN or whatever, but on either side of the atlantic? How would I make sure our firewalls played along? 2. Same thing, but on Windows machine. Destination machine is xp pro. Firewall is zonealarm. Can I connect to it and do things on its desktop like I did on windows with "remote assistance"? Thanks for any advice or pointers!
