I am running Sierra successfully on a 2007 24"  iMac (7,1) after upgrading the CPU from a T7700 to a T9500 (Penryn) and applying dosdude's Sierra patch.  (If your 2008 already has a Penryn chip you don't need to do that part!)  Also having the Broadcom wifi incompatibility problem, but I don't really need that on this machine. The unsupported wifi does not prevent Sierra from running.  The system just doesn't see any wifi hardware.  If I do someday want to replace the wifi hardware, does anyone know what model would work and has the right form factor for this machine?
