Baptize your Mac to make it work with TimeMachine

Yesterday I got myself a new MacBook, hooked it up with the iMac and used the Migration Assistant Utility to transfer data from my main computer. Then I turned TimeMachine on and chose my TimeCapsule as the destination drive, but I got the message that “Time Machine cannot create the disk image” (not a verbatim copy, may differ slightly).

Hm, first I checked disk space but there’s enough space in the Capsule to hold the image. I rebooted, updated software, reboot but still nothing. Then it occured to me; I checked out the computer’s name in the “Sharing” tab in the Preferences app, and saw that it was blank! After giving it a name and initiating a backup, it worked.

Of course I had given a name to the MacBook, but I guess either the initial configuration or the Migration Assistant did something wrong.
