Thx Dave for your quick reply. I guess I will use the ext. drive to just backup the iMac HD then and use some other sync software to sync the PowerBook and the iMac. Sandbox will be left for later :-)
In this respect, can anyone recommend a stable and reliable sync software? I was looking at
Chronosync as well as
Synk. Anyone using either of these (or other apps) and can share experience...?
Thank you
