The MacBook Pro’s captive battery made its debut in the late 2009 models, extending the length of time you can use the laptop on a single charge. Also on the left hand side is a battery life indicator button with seven light status gauge. The ports located on the left-hand side of the MacBook Pro’s case remain identical to the last generation: two USB 2.0 ports, one gigabit ethernet, one FireWire 800, one SD card slot, MagSafe power port, and audio line in and line out ports supporting optical digital and analog signals. The case design is unchanged, and there’s still a backlit keyboard, multi-touch trackpad, and an 8x DVD-burning SuperDrive.

An Apple representative said that this feature is unique to the new MacBook Pros and is not available through a software update on older Mac laptops.
If you have an iPhone, iPod touch, or iPad, the scrolling works the same way: swipe your finger up or down to scroll through a document, and the momentum continues the scrolling until it slowly stops. One interesting note about the automatic switching: Any application that uses the required frameworks can trigger a switch from integrated to discrete graphics.Īlso new is the support for inertial scrolling on the Multi-Touch glass trackpad. Previously, a user had to decide which graphics to use and switching between them required logging out and back into OS X. Not only are the graphics processors new to these systems, there’s also a new automatic graphics switching technology developed by Apple that looks for frameworks used by individual apps at launch (such as OpenGL and Core Animation) to decide when to seamlessly switch from its energy-sipping integrated graphics to the higher-powered discrete graphics processor. But for applications that require more horsepower, the system can use its discrete Nvidia GeForce GT330M graphics, with 256MB of dedicated graphics memory. The new models can use Intel HD integrated graphics (which shares 256MB of main memory with the CPU) for general-use applications, like iTunes, Mail and Safari. The desktop Core i5 does not support Hyper-Threading, though the mobile version does.Īll 15-inch MacBook Pros now offer both integrated and discreet graphics- previously, the entry-level 15-inch MacBook Pro had only integrated graphics. The mobile versions of the Core i5 and i7 used in the MacBook Pro differ from the desktop version found in the 27-inch iMac, which has four physical processing cores. Turbo Boost can increase the clock speed of the 2.4GHz Core i5 processor up to 2.93GHz, for example. Another i5/i7 technology, Turbo Boost, allows the processor to speed up for a short period of time when necessary, or shut down unused cores and give the resources to the cores in use. The processors have dual cores, but OS X treats them as having four cores. The Core i5 and i7 processors have a few interesting performance features, including Hyper-Threading, which uses virtual cores to double the amount of processing cores presented to the operating system. The new 15-inch MacBook Pro models drop the Intel Core 2 Duo processors (used in Apple’s laptop line since late 2006) in favor of Intel’s Core i5 and Core i7 mobile processors.
See Macworld’s 13-inch MacBook Pro review What’s new? At the top of the line sits a $2199 model with a 2.66GHz Core i7 processor and a 500GB drive its $2299-predecessor had a 2.8GHz Core 2 Duo model with 4GB of RAM, and a 500GB hard drive. The next step up the line is a $1999 system with a 2.53GHz Core i5 processor and a 500GB hard drive, which takes the place of a $1999 2.66GHz Core 2 Duo-based system with 4GB of RAM, dual graphics, and a 320GB hard drive. The $1799 entry-level system comes with a 2.4GHz Core i5 processor and a 320GB hard drive it replaces a $1699 model with a 2.53GHz Core 2 Duo processor, 2GB of RAM, a 250GB hard drive, and integrated graphics only.
