Hi Rick,

According to the Aperture documentation you can restore from a Vault to a different computer.

"If you buy a new computer or use another system at a different location and want
access to the Aperture library, you can install Aperture and then transfer the library
from your vault (on your backup disk) to the other computer. If you experience
equipment failure or other unexpected events, such as fire or weather-related damage
to your equipment, you can easily restore the entire library to your new computer from
a backup disk."
