What ports are provided by the “Unibody” MacBook Pro?
The 15-Inch “Late 2008/Unibody” MacBook Pro models have one Mini DisplayPort, two USB 2.0 ports, a Firewire “800” port, a Gigabit Ethernet port, optical/digital audio input/output ports, a Kensington security port, and a “MagSafe” power connector. Additionally, these models have AirPort Extreme (802.11a/b/g/n) and Bluetooth 2.1+EDR as well as an ExpressCard/34 slot. The 15-Inch “Mid-2009” and “Mid-2010” MacBook Pro models, on the other hand, have an SD Card slot instead of an ExpressCard/34 slot. The 13-Inch “Mid-2009” and “Mid-2010” MacBook Pro models have the same ports as their 15-Inch brethren, except that they lack optical audio in and instead pack the same “combined optical digital output/headphone out (user-selectable analog audio line in)” port used by the iPhone. All 17-Inch “Unibody” MacBook Pro models have the same ports as the 15-Inch models and add a third USB 2.0 port. All 17-Inch models — regardless of release date — also have an ExpressCard/34 expansion slot.
