You can run Software Update (Apple menu) right away OR, if you like to be thorough, download/run the 10.6.8 v 1.1 Combo Updater again, reboot, then run Software Update. Turn on your target system (in a two-partition dual-boot system, hold down the option key during boot to select the Snow Leo partition manually).After that's shut down, you may shut down your target computer and disconnect the Firewire cable. Then run the 10.6.8 v 1.1 Combo Updater you downloaded earlier.Let itįinish installing and then you'll go through set up steps. System will auto reboot but it will boot off your target system's hard drive. Proceed and let it do its thing: your host If you are dual booting, then you'll set this to the volume you reserved for Snow Leo.

Pop your Mac box set/retail/bootable Snow Leopard disc into your host computer's optical drive.Remember, you are using your host computer to reformat your target drive's partition, so your target is the name that should be showing up when you set about partitioning. When you're ready, you click the "Apply" button and it will warn you what drive it's going to modify and what will happen when you proceed. If you want 1 large partition, then click the dropdown that says "Current" and change to "1 Partition." Click the "Revert" button to start over. If you want to dual boot, hit the (+) symbol and add a partition, set their respective sizes (I wouldn't go less than 10-15GB for the smaller partition). Now you've got to make a decision: do you want to dual boot Lion and Snow Leopard? Do you want 1 large partition with Snow Leopard? You cannot expect to change this later so you have to decide now. When you've got the correct target-to-downgrade drive, click on the tab that says Partition. Look at their icons in the list (one might be an orange Firewire icon) or read the data down below to see if Connection Bus says Firewire ( something like this.) If both of your computer hard drives are named, for example, "Macintosh HD," then look for other hints. When you click on the line with the hard drive size & brand-model, it will give you more information about it down below. Each drive will show up as a cluster of names (2 or more) with the first line showing the hard drive size & brand-model and the second line showing your regular name for it. Be very very very careful here, we're going to repartition your target/downgrade drive and we must be sure of the correct one! You want to find the target computer-you-want-to-downgrade's hard drive name in the list on the left, NOT your host hard drive names. System mount on your host desktop (it might only appear on left side of a folder/Finder window if you've got your hard drives hidden from your desktop.) Back at your host computer, you will now see the hard drive name of your target.
