I really need to downgrade from Yosemite, which came pre-insalled on this iMac that I just bought... All the downgrade methods I've tried do not work and it seems to just want to install Yosemite. I have wiped drive clean, tried internet recovery, etc.. Any help would be appreciated 😟
iMac with Retina 5K display, OS X Yosemite (10.10.1)
It’s not possible to downgrade a Mac to a Mac OS X version older than the one it originally shipped with.

Ugh, unbelievable... I might have to return. Thanks for the reply 😐
It's not possible. You'll either have to solve your problem with Yosemite, whatever it is, or return the machine.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.
Actually it is possible to downgrade to a later version of OS X than the machine shipped,
with but only on some models, for example is it possible to downgrade a Late-2011 MacBook Pro
to OS X 10.6 Snow Leopard, allthough it shipped with 10.7 Lion and it runs perfectly, i've done that to mine
and now it tripleboots Yosemite, Snow Leopard and Windows 8.1. I dont know if downgrading could work on a new iMac
but it seems like you tried it, why or when does it fail?
