Apple slims down iMac in latest update

At Tuesday’s Apple Special Event, the company introduced a redesigned iMac that Apple senior vice president Phil Schiller called, “the most beautiful Mac we have ever made.”

While the familiar almuninum design remains, the new iMac is much thinner than its predecessor. The company reengineered the iMac’s internals and display, and Apple says the display system is 45 percent thinner and 8 pounds lighter.

The new iMacs are available in 21.5- and 27-inch models, with displays that support native resolutions of 1920-by-1080 pixels and 2560-by-1440 pixels, respectively. Previous models of the iMacs had a 2mm air gap between the glass and the display; that gap has been removed in the new iMac. Apple now laminates the display directly to the glass, and the company says the full lamination will improve optical quality.

Besides the new design, the other marquee feature of the new iMac is the Fusion Drive, which is a hybrid storage technology that combines flash storage with a hard drive. The Fusion Drive comes with 128GB of flash storage used mainly by the operating system to provide fast performance. The hard drive portion of the Fusion Drive is available in 1TB or 3TB capacities.

However, the Fusion Drive isn’t part of Apple’s standard configuration for the iMac—it is a build-to-order option. Apple has yet to release upgrade pricing for the iMac models with a Fusion Drive, though it's worth noting that the 1TB Fusion Drive upgrade for the 2.3GHz Core i7 Mac mini is $250.

Apple’s Phil Schiller shows off the latest iMac on Tuesday.

As seen with the Retina MacBook Pro, Apple is relying on Thunderbolt and USB 3.0 for connectivity. The iMac has two Thunderbolt ports and four USB 3.0 ports, as well as a gigabit ethernet port. FireWire is no longer offered on the iMac, and users of FireWire devices will need an adapter.

The iMac also features a built-in FaceTime HD camera, dual microphones, stereo speakers, built-in Wi-Fi, and Bluetooth 4.0. The optical drive is no longer included, and the SDXC card slot that was located next to the optical drive can now be found on the back of the iMac, between the headphone jack and the USB 3.0 ports.

The 21.5-inch iMacs have only two RAM slots and support a maximum of 16GB of memory. The 27-inch iMacs have four RAM slots and support a maximum of 32GB of memory.

Apple offers four models of the new iMac.
