The 2012 Air ships with OS X 10.7 (Lion)-including Apple’s battery estimates are based on “wirelessly browsing 25 popular websites with display brightness set to 50 percent.” We test using tasks designed to drain the battery more quickly, but our results show roughly four hours of battery life for the 11-inch Air (slightly better than the 2011 model’s battery life), and around five hours of use for the 13-inch Air (about the same as its predecessor). The 11-inch Air has a claimed battery life of up to 5 hours, with the 13-inch Air boasting up to 7 hours. Inside the case is a multi-cell, custom-fit-yes, and still non-user-replaceable-battery system that gives the Air line excellent battery life, despite its slim profile. Apple hasn’t advertised any speaker changes, but compared to my 2010 MacBook Air, audio produced by the 2012 Air’s speakers is much clearer with much better detail-it sounds less like an old transistor radio. The Air still includes tiny stereo speakers just in front of the hinge, positioned so their sound is reflected off the screen bezel and towards you. I didn’t have a 2011 Air on hand to measure.) (One minor difference I noticed when comparing the screen of the 2012 11-inch Air with that of the 2010 version is that the 2010 screen tilts back an additional 5 degrees. As with previous Air models-and the new Retina MacBook Pro-the new Air’s display suffers much less from glare than the standard MacBook Pro models, which have a large, reflective layer of glass over the entire screen and frame. With a resolution of 1366 by 768 pixels on the 11-inch model and 1440 by 900 on the 13-inch, it’s not a Retina display, by any means, but it’s bright and clear with outstanding colors and viewing angles. The MacBook Air’s feature evolution (click for full-size chart) (The differences? The Air’s F-key row uses half-height keys compared to the desktop keyboards, and its bottom row of keys is ever-so-slightly shorter.) There’s also the large, Multi-Touch trackpad that’s ideal for using gestures in OS-it remains the best trackpad I’ve used on any laptop-and an LED-backlit, widescreen, glossy display surrounded by an aluminum bezel. The 13-inch Air weighs just under 3 pounds, with the 11-inch version weighing in at just under 2.4 pounds.įlip open the screen, and you reveal a full-size, backlit keyboard-even on the 11-inch model-that uses the same low-profile, flat keys as Apple’s current desktop keyboards. Both the 11-inch and 13-inch Airs are thin wedges of unibody aluminum-just under 0.7 inch thick in the back and just over 0.1 inch thick in the front-though obviously with different footprints: The 13-inch model is 12.8 inches wide and 8.9 inches deep, while the 11-inch Air is just 11.8 inches wide and 7.6 inches deep. In June 2014, the 2.9 GHz model received a reduction in price to $1099, and the price of the 2.8 GHz model was reduced to $1299.Through the Air’s now-six iterations, the laptop’s external design has remained essentially the same.
2012 MACBOOK PRO 13 I7 BLUETOOTH
Introduced in June 2012, the MacBook Pro (13-inch, Mid 2012) improved on its predecessor, the MacBook Pro (13-inch, Late 2011) with faster processors and graphics, more storage, USB 3.0 and Bluetooth 4.0.
2012 MACBOOK PRO 13 I7 INSTALL
Though Apple officially lists the maximum RAM as 8 GB, it's possible to install 16 GB of RAM using two 8 GB DIMMs. A single 3.5mm jack could be used for analog or optical audio out, or analog audio in.
Actual usage varied with graphics load, resulting in slightly less RAM available for system use. Though reported as a 384 MB graphics system, this was actually a minimum. The MacBook Pro's second graphics chipset used a portion of main memory as VRAM. The 2.9 GHz model had a 4 MB on-processor 元 cache.
