Here we’ll guide you through all the necessary steps to get Mac OS X Snow Leopard installed on your Dell Mini 9 netbook, including updating it safely to 10.6.2.
Requirements:
- Dell Mini 9 with at least 8GB of hard disk space
- Mac OS X Snow Leopard retail disc
- Intel-based Mac with DVD-ROM drive and USB port
- 8GB or larger external USB drive (hard disk or flash drive)
- NetbookBootMaker
- NetbookInstaller
On your Mac with DVD-ROM drive and USB port:
- Insert the Mac OS X Snow Leopard retail disc into the Mac’s DVD drive, and connect the external USB drive to the Mac too.
- If your Mac is running Mac OS X 10.6 or later then launch the ‘Disk Utility’ application located in your ‘Utilities’ folder, and skip to step 7. Else, proceed to the next step.
- Double-click on ‘Mac OS X Install DVD’ and then double click the ‘Install Mac OS X’ icon.

- Click the ‘Utilities’ button.

- Click the ‘Restart’ button. The Mac will now boot from the Mac OS X Snow Leopard retail disc.

- Once you’ve selected your language, click on the ‘Utilities’ menu and select ‘Disk Utilitiy…’.
- Select the external USB drive in the left-hand column, ensure that you click on the parent icon which states the drive capacity, e.g. “931.5 GB”.

- Select the ‘Partition’ tab and then under “Volume Scheme:” click on ‘Current’ and change it to ’1 Partition’.

- Change ‘Name:’ to “OSXDVD” and ensure that ‘Format:’ is set to “Mac OS Extended (Journaled)”.

- Click ‘Options…’, select “Master Boot Record” and then click ‘OK’.

- Click ‘Apply’ and then ‘Partition’ and give the Mac a moment to format your USB drive and create the new partition.

- Next we need to copy Snow Leopard to the USB drive: select the ‘Restore’ tab.

- From the left-hand pane, click and drag the ‘Mac OS X Install DVD’ icon to the ‘Source:’ field and release.

- From the left-hand pane, click and drag the ‘OSXDVD’ icon to the ‘Destination:’ field and release.

- Tick the ‘Erase destination’ box, then click the ‘Restore’ button and then click ‘Erase’. Allow between half an hour to 2 hours for the copy to complete.

- Once complete, if you skipped to step 7 at step 2 in this guide, you can now skip to step 19. Else, proceed to the next step.
- Quit ‘Disk Utility’ and from the ‘Utilities’ menu, select ‘Startup Disk…’.
- Select the Mac’s normal startup disk, click ‘Restart…’ and then click the ‘Restart’ button. The Mac will now reboot from its hard disk.

- Launch the ‘NetbookBootMaker’ application and from the select menu labelled ‘Select USB Partition:’ select the USB drive which is now titled ‘Mac OS X Install DVD’ and then click ‘Prepare Boot Drive’ (you’ll be prompted for the Mac Administrator’s username and password).

- Once complete, you can eject the USB drive and disconnect it from the Mac.
