new iMac's Not Backwards Compatible!

[jsidoti]

I did everything under the sun to no avail!
I called Apple and they confirmed the new iMacs Are 10.6 and newer only. You cannot load Leopard on them. Just thought you might want to know. If you were thinking to get that new awesome screen, but run Leopard... No Go

no mac has been able to run a previous os than what was initially installed

hardly news

its driver issue related

Yep, generally you cannot even boot from the retail OS disk if it is older than the machine.

Likely the current machines take a modified version of 10.6.1 with updated drivers ... so they likely won't boot from Mac OS X SL DVDs until the 10.6.2 or 10.6.3 retail DVDs hit the shelves.

Of course if you lose the DVDs, it is just about the same price to get new restore DVDs as the retail OS these days.
