MacBook Pro with Retina display
Apple sells two types of MacBook Pros. Let's cover the Retina MacBook Pro first.
What is it? The Retina MacBook Pro features a high-density display with so many pixels that images and text look especially smooth and clean. At normal viewing distances, you can't discern individual pixels.
Who's it for? The Retina MacBook Pro is for the demanding user who wants a portable computer that also performs well. Retina MacBook Pro models sit at the top of the performance chart of Mac laptops.
What are the specifications? The Retina MacBook Pro is available in screen sizes of 13 inches and 15 inches.
There are three 13-inch models. The $1299 model has a 2.7GHz dual-core Core i5 processor, 8GB of memory, and 128GB of flash storage. The $1499 model has a 2.7GHz dual-core Core i5 processor, 8GB of memory, and 256GB of flash storage. The $1799 model has a 2.9GHz dual-core Core i5 processor, 8GB of memory, and 512GB of flash storage. All three 13-inch models have an Intel Iris Graphics integrated graphics processor.
Apple has two 15-inch Retina MacBook Pros. The $1999 model has a 2.2GHz quad-core Core i7 processor, 16GB of memory, 256GB of flash storage, and Intel Iris Pro integrated graphics. The $2499 model offers a 2.5GHz quad-core Core i7 processor, 16GB of memory, 512GB flash storage, Intel Iris Pro integrated graphics, and a discrete 2GB AMD Radeon R9 M370X graphics processor.
The screen is the Retina MacBook Pro's marquee feature. The 13-inch Retina display has a native resolution of 2560 by 1600 pixels, and OS X offers a scaled resolution up to 1680 by 1050 pixels. The 15-inch Retina display has a native resolution of 2880 by 1800 pixels, and OS X's highest scaled resolution on those laptops is 1920 by 1200 pixels. These high-scale resolutions can accommodate the workspace of a larger-screen standard Mac laptop on a smaller Retina MacBook Pro, if you can tolerate the smaller icons, text, and other graphics on screen. If you use a third-party app such as QuickRes, you can set the Retina screen to use resolutions higher than the scaled settings OS X offers, including the native resolution.
The Retina MacBook Pro does not have a SuperDrive, so if you need one, you'll have to buy an external USB optical drive.
How do I connect stuff? No need to worry about wireless connectivity: The Retina MacBook Pro has Wi-Fi and Bluetooth.
It's the wired connectivity you need to be concerned with. The Retina MacBook Pro has two Thunderbolt 2 ports, two USB 3.0 ports, an HDMI port, and that's it. If you want to connect a FireWire device, you'll have to use a Thunderbolt-to-FireWire Adapter. Fortunately, you can use USB 2.0 devices with the USB 3.0 ports without a problem.
