For most users, a cloning utility like. SuperDuper! (and other utilities like Carbon Copy Cloner or Synchronize! Pro X) allow you to create a bootable, full backup of your current Mac OS X installation. ( You do have a back up drive right)?

You may want to hold off on running any of the popular disk directory repair/optimization utilities under Mac OS X 10.5 until further word is released by their developers. These include DiskWarrior and TechTool Pro. But as soon as you get the word include these tools. They are a must.

Finally read the Mac rags so as to keep up with what's going on. You will get explanations to issues that may crop up.
