Announcing another round of improvements to its product line today, Apple has said that it has updated the specifications of its MacBook Pro and MacBook Air models, boosting processing speed and memory but also reducing prices across the range.

From today, Apple’s 13-inch Retina-enabled MacBook Pro starts from $1,499 with a 128GB SSD and will offer a new 2.6 GHz processor and 256GB SSD for $1,699.

The 15-inch MacBook Pro with Retina display now has a 2.4 GHz quad-core processor and will now allow customers to upgrade to a new 2.7 GHz quad-core processor with as much as 16GB of memory. The company has also reduced the cost of the 13-inch MacBook Air (256GB SSD), which now stands at $1,399.

The mid-season specification bump suggests that Apple may have been able to reap the benefits of reduced component costs, allowing it to further boost its Mac lineup with little or no affect to margins.

iDownloadblog reports that if you have bought one of the updated MacBook Pro or MacBook Air models in the past two weeks, Apple will upgrade your notebook free of charge.
