I have an Early 2009 24" iMac C2D 2.93 MHz and was wondering how long Apple will continue to support Macs with the C2D processor with new releases of OS X? Thankfully Mavericks is supported on my iMac, but I am thinking this may be the last major release to support my iMac. The Core 2 Duo was last released by Intel in 2009 (best I can research) and the last Apple products introduced with C2D were in mid-2010 (MacBook/MacBook Pro). Possibly one more release after Mavericks then that's it? Thoughts?
