I Still Believe in Murphy’s Law

An oldie but goodie from the DF archives four years ago: my recommendations for installing major Mac OS X software updates:

So, in short:

  1. Do a complete backup clone to an external FireWire drive.
  2. Test that the backup is indeed bootable and up to date.
  3. Unplug the backup drive.
  4. Pop in the installer DVD and launch the “Install Mac OS X” app.

Step 4 has been obviated by the App Store, of course, but steps 1-3 still stand. Do not assume that going from 10.6 to 10.7 will be an easy or seamless transition. If you really want to be prepared, check out Joe Kissell’s $10 e-book, Take Control of Upgrading to Lion.
