The mac is a 10.4.11,procesor-2.16 ghz memory 2gb 667 MHz DDr 2, intel core 2- duo. It has a built in Audio, Bluetooth, Disc Burning/DVD Player which has excellent picture and sound, Fire channel, 4 USB ports, Air Port/WIFI, built in Ethernet, built in firewire, Screen is 20.5 wide, 24 Diagonal, 13 High. Actual monitor is 18x23. I believe it is 2007. I purchased a keyboard and mouse separately and will include with it. contact me either by email, test or call 613-488-2047
