switching from Lion to Snow leopard

[Alwyn]

Hi guys
If you have a reasonably up to date installation disk for Snow Leopard you should be able to install it on a machine running Lion.
To do this you will need to partition your hard drive to create a separate area for SL to reside in. Do this in DISK UTILITY without removing any of your existing files, etc.
You will then be able to boot from this drive by holding down the option key as you start up, which should result in your seeing the disk icon for the partition containing SL.
Click and your machine should start in Snow Leopard.

No I don't think I'll go there. If I get sufficiently familiar with Lion I may decide to upgrade the Snow Leopard iMac.
