On July 20, 2011, Apple released an updated model in the same form factor as the prior model. The new model was powered by new dual-core Intel Core i5 and i7 processors, had a backlit keyboard, Thunderbolt instead of Mini DisplayPort and Bluetooth was upgraded to v4.0. Maximum flash storage and memory options were almost identical.

"Thinnest" disputes

At the launch of the first MacBook Air in January 2008, Apple claimed it to be the thinnest laptop in the world. However, the by-then discontinued Mitsubishi Pedion, released in 1998, was thinner than the Macbook Air at its widest point, being a rectangular 0.72 inches (18 mm). The first MacBook Air was thicker at its thickest point (0.76 inches (19 mm)), but it tapered down to 0.16 inches (4 mm), leading to some controversy over the thinnest laptop claim.

The likewise discontinued Sharp Actius MM10 Muramasas was also described in some sources as thinner than the Macbook Air, being 0.54 inches (14 mm) thick at its minimum. It, like the MacBook Air, was a tapered design, with a maximum height of 0.78 inches (20 mm), in fact slightly thicker than the MacBook Air.

Since the release of the first MacBook Air, a number of ultrathin laptops have been released, including the Dell Adamo

, launched in March 2009, and a constant 0.65 inches (17 mm) thick, and the even thinner Adamo XPS, launched September 2009, only 0.39 inches (10 mm) thick. Also, the Sony VAIO X-series, launched in October 2009, is 0.55 inches (14 mm) thick throughout the entire body. As well, HP's VoodooPC ENVY 133 series which was released in June 2008 is 0.70 throughout. Apple has subsequently dropped the 'world's thinnest laptop' claim from their marketing.

Early issues

The flip-down hatch on the side of the original MacBook Air is a tight fit for some headphone plugs and USB devices, requiring users to purchase an extension cable. Apple has removed the flip-down hatch on the late 2010 model in favor of open connection ports as on most other laptops. Since the release of the first-generation product, some MacBook Air users have complained of overheating that caused CPU lockup. The effect can be seen at CPU temperatures as low as 150 °F (65.6 °C) and worsens with higher temperatures. Apple released a software update in early March 2008 to fix the problem with mixed results: the deactivation of 1 CPU core appears to have been corrected; however, the runaway kernel problem remains for at least some users. The problem is aggravated by system-intensive tasks such as video playback or video chatting. Due to a more mature manufacturing process, the CPUs in the second-generation MacBook Air perform better under load as the first-generation chips ran hotter, requiring throttling the processor to avoid overheating, further degrading performance.
