This page list a way to do a clean install of Snow Leopard without losing any of your settings. This sounds pretty darn good since my mac did get a bit slower over time.
The method basically involves copying your existing drive to an external one, then doing an Erase and Install from the installation DVD.
After the installation, supposedly, I'll be presented with an option to migrate settings from another Mac.
I am not all that familiar with the Mac, hence what is probably a simple question. With this migration option, will I be able to copy over all my applications or will I have to reinstall them from scratch?
