The Mid 2007 MacBook Pros shipped with OS X 10.4.9 Tiger and can run OS X 10.11 El Capitan. If a second high-powered device is attached, it will behave like a normal bus-powered hub and only provide 100 mA per downstream port. Unlike earlier models, where every USB port could provide 500 mA of power, only a single high-powered device can be attached to the USB ports, and software will enable just one of its downstream ports to supply 500 mA of power. The new model is also 0.2 lb./90g lighter than its predecessor.

Still, the biggest news is the “green” display, which is backlit by LEDs (for better battery life) and mercury-free. And they also run their CPUs a tiny bit faster. 2 GB of RAM is now standard with a 6 GB ceiling (up from 3 GB). They include Nvidia GeForce 8600M GT graphics, an improvement over the ATI Mobility Radeon X1600. The Mid 2007 MacBook Pro models (15″ and 17″) use Intel’s new Santa Rosa chipset and the Merom CPU on an 800 MHz system bus (which can be dynamically adjusted to save power), up from 667 MHz on last year’s model. Other than that, the specs don’t seem much different than it’s predecessor. The 15″ MacBook Pro became Apple’s first notebook computer with LED backlighting when it was introduced on June 5, 2007.
