Snow Leopard Clean Install I have an iMac from 2010 and the Snow Leopard DVD and I am trying to do a clean install of Snow Leopard on it. Then, if I use the Install Snow Leopard option from the DVD, when it restarts it hangs on the apple icon, but if I restart the Mac nothing happened to my HDD.

I also tried using booting the DVD by holding 'Option' when I restart it, and after I choose to boot from the DVD, it hangs on the apple icon and I can hear that the DVD stop spinning.

I boot it on safe mode and use the Apple Hardware Diagnose Tool and no issues have been shown. I will appreciate if anyone have an idea of how I can perform this clean install. Thanks!
A Snow Leopard DVD may not work on a 2010 iMac. For example, according to everymac.com a iMac11,2 (21.5-inch, Mid-2010) came preinstalled with OS X 10.6.3. So, if your Snow Leopard DVD is OS X 10.6 then you should expect problems when booting.


  Note: While one may think 10.6 should be 10.6.0, doing so would differ from Apple conventions. For example, see an image of the Snow Leopard 10.6 DVD or the system requirements for the Mac OS X 10.6.8 Update Combo v1.1.
