Hi Gavin, The below solution should work, although please note that I have not tried it myself and that I have only been using a Mac for a week. This method will not keep any of your files, settings or applications, so be sure to back them up to an external drive, optical media or online backup service before you begin. Do not use Time Machine in Lion, as when you restore your files after the Snow Leopard installation Lion will be restored also.
If you have the Snow Leopard install DVD: 1. Boot into Lion Recovery mode. To do this, reboot/power on your Mac and either hold down Command-R, or hold down Option and select Recovery HD from the list of disks in the Startup Manager (wait about 15 seconds after you've heard the Apple chime to be safe, and then hit the right arrow key followed by enter). 2. If VoiceOver doesn't begin talking (I can't remember off the top of my head whether it starts up automatically in recovery mode or not), hit Command-F5 to load it. 3. In Disk Utility, locate your Macintosh HD and navigate to the Partition tab. 4. Find the Partition Layout drop-down menu and choose 1 Partition. 5. Select the Erase tab, make sure that Mac OS Extended (Journaled) is selected as the filesystem and hit the Erase button. 6. Restart your Mac with the SL DVD in your optical drive and hold down the C key to boot from it. 7. Follow the Snow Leopard installation steps. 8. Restore your files, settings and applications. -- James Scholes http://twitter.com/JamesScholes -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
