I’ve been putting off the upgrade to Snow Leopard because PGP doesn’t support it yet.  But last night my wireless card wouldn’t connect to my home network.  I played with it for about 30 minutes, but I couldn’t figure out what was wrong with it.   Rather than continue to hit my head against that wall, I decided it was time to erase everything and do a fresh install of Snow Leopard.  The install went smoothly, as most Mac installs do.  I reformatted the hard drive in the process, and it’s nice to have a fresh install.

Although I’ve written about it before, I need to give a thumbs up to Time Machine.  Before formatting the drive, I connected a USB drive and backed up using Time Machine (now I had two backups: my regular, wireless TM backup and this USB TM drive).  During the installation of Snow Leopard, it asked if I wanted to restore settings from a Time Machine backup.

The restore not only restored my data files, it entirely set up my computer to match my old install.  This includes:

  • All applications, including app settings I’ve customized.  Apps even open the same size as I last closed them.
  • Photos, music, videos, etc. (not only the files, but the setup of them in the different programs)
  • Login items, passwords, user accounts
  • Screen saver settings (even the ones I’ve added to the computer), desktop background, etc.
  • Email settings, signatures, sent mail, etc.
  • Wireless and other network settings and passwords
  • Web browser bookmarks, saved passwords, history, etc.

It took about 1.5 hours to restore my data and settings.  My computer then looked as if I hadn’t done a fresh install.  Time Machine is one of the best things about the Mac.

(I should note that during the restoration, I chose not to restore a couple of things (like database settings) because I wanted to do fresh installs of them.)
