Partitioning

Hi, Rick. To determine the size Sandbox you need, the easiest thing to do is to create one before you partition. So, use the Sandbox script to make a Sandbox on the external using Smart Update or Erase, then copy. Once done, look at the amount of disk space it takes, and add about 20-30% or so. Then, partition as appropriate.

You only need to run from the Sandbox when you're trying out something you don't trust. So, if 10.4.9 comes out and you want to test it before committing to it, update your Sandbox, start up from it, and then install 10.4.9 there.

Similarly, if a new drive or something comes out that you want to "isolate" in the Sandbox before you commit to it, boot from the Sandbox, try it out.

Once you've determined what you want to do, you can boot back and install on the "real" drive.
