If I want to be able to 'see' one of my Macs from the other Mac - browse it's hard drives and copy files from them - then is it simply a matter of sharing the the drives of one of the Macs, and then I'll be able to see that Mac from the other Mac in Finder?
That's assuming that both Macs are on the same network.
