About 6 months ago I downloaded a wonderful crypting utlity called Cypher.app. Works beautifully with Leopard.
As I wanted to download another copy for a second Mac I have I tried to get at its homepage, as indicated by the app (http/homepage.mac.com/jhammer/cy)
but the site exists nomore...
I, too, would buy a new Mac Pro. As Leopard seems to need some fixing, I shall wait and see what's coming up in 3 to 6 months from now, hoping that it'll be rather 3 than 6, because I'm impatient to put my fingers on OSX3 and Objective C2 !
