Apple MacBook Pro "Core i5" 2.3GHZ 13" Early 2011 Model A1278 MC700LL/A

The MacBook Pro "Core i5" 2.3 13-Inch (Early 2011/Thunderbolt) featured 
a 32 nm "Sandy Bridge" 2.3 GHz Intel "Core i5" processor (2415M),
with two independent processor "cores" on a single silicon chip,
a 3 MB shared level 3 cache,
4 GB of 1333 MHz DDR3 SDRAM (PC3-10600) installed in pairs (two 2 GB modules),
a 320 GB Serial ATA (5400 RPM) hard drive,
an 8X DL "SuperDrive",
an Intel HD Graphics 3000 graphics processor that shares 384 MB of memory with the system,
an integrated FaceTime HD webcam, and
an LED-backlit 13.3" widescreen TFT active-matrix "glossy" display (1280x800 native resolution).

Connectivity includes
AirPort Extreme (802.11a/b/g/n),
Bluetooth 2.1+EDR,
Gigabit Ethernet,
a Firewire "800" port,
two USB 2.0 ports,
audio in/out,
an SDXC card slot, and
a new "Thunderbolt" port that is backwards compatible with Mini DisplayPort
and, likewise, supports an external display at 2560x1600 and passes an audio signal.

Thunderbolt also supports other peripherals that use the Thunderbolt standard which provides up to 10 Gbps of bandwidth in both directions.

This model uses a "Unibody" aluminum case design -- milled from a single piece of aluminum -- and has
a backlit keyboard,
a "no button" glass "inertial" multi-touch trackpad, and
a non-swappable battery design.

Compared to its predecessor, this model has a very similar external enclosure, apart from a higher-resolution webcam and the aforementioned Thunderbolt port. Internally, however, it has a significantly faster architecture, faster RAM, and improved graphics.

Maximum MacOS Supported: X 10.13 High Sierra
