It took 15 minutes to complete on my Macbook. It should look like this:Ĭlick 'Restore'. Make sure 'Erase Destination' is checked. dmg from the list on the left of Disk Utility into the 'Source' field, then drag your newly created 'Snow Leopard Installer' partition into the 'Destination' field. dmg you just dragged in from the list on the left, then the 'Restore' tabĭrag the Snow Leopard.

Open Disk Utility, and drag the Snow Leopard. You should leave your system alone whilst it is applying the changes, and it should not take any longer than 1 hour. This should take 5-10 minutes, but don't worry if it takes more (especially with a larger hard drive). The size of this new partition should be 10GB, it should be formatted with 'Mac OS Extended (Journaled)' and the name should be something snazzy like 'Snow Leopard Installer'. Press the + (plus) to create a new partition. You can do this by dragging the partition up, or by manually changing the value in the text box. Select the 'Partition tab' and decrease the size of your main partition (In my case 'Macintosh HD') by 10GB.

This is not 'Macintosh HD', in my case it is '260.06 GB Hitachi HTS5.' Select the Hard drive you want to resize and put the installer on. This can be slow (eww, USB), and not everyone has a large enough external drive.Īll I did was re-size the hard drive inside my Macbook to create another, smaller partition (10GB) and put the Snow Leopard installation files on there. A lot of people have been suggesting to use an external hard drive to put the Snow Leopard installation media on.
