Having upgraded to a latest spec version my 2011 27" iMac is surplus to requirements.
Owned this for over 7 years and it has never put a foot wrong and is in near mint condition - only used for surfing, photo editing, office work etc. Many of my finest replies on here have come on it so I guess it should really be in the British Library.
Comes with wireless keyboard but no mouse (I left the Apple mouse in a drawer for years and the batteries leaked!!). I always used a nice USB mouse.
I have secure erased and formatted the drive and reloaded the original OSX (Snow Leopard) using the original DVD’s - this can be updated through the app store. There is also a DVD for applications like iLife, iMusic etc which I have not installed.
CPU: Intel i5 2.7 GHz
