MacBook Air will definitely have a new version at WWDC 2013.
A piece of SKU code that appeared a few days ago almost confirmed the appearance of the next-generation MacBook Air at WWDC 2013. Models with attached names include: MD711LL / A, MD712LL / A, MD760LL / A and MD761LL / A may be the MacBook Air or MacBook Pro Retina . Each product line has two different screen versions and two separate configurations.
Both MacBook Air and MacBook Pro use the latest Intel Haswell processor platform. However, there is almost no change in the style of the MacBook Air. In this upgrade Apple will pay more attention to other details such as USB 3.0; Bluetooth Smart; NFC and Thunderbolt connection.
MacBook Pro Retina is the only model with rumors that it will be thinner.
After a year of stirring up the laptop market with ultra-smooth screens, the hopes put on a more comprehensive upgrade to the MacBook Pro Retina. However, like the MacBook Air, the device will have a major change in the internal configuration instead of further refining the screen or using a new design. Moreover, the 13-inch version will appear later than the 15-inch version of the same route last year.
In addition to the Intel Core i 4th generation processor, the MacBook Pro Retina 2013 is expected to increase the power of discrete graphics cards with Nvidia's GeForce 700M chip. Some software connected to the iPhone or iPad is also integrated to complete the Apple ecosystem.
In addition, Slashgear said there is still a small hope for Apple to make it thinner.
Mac Pro can be upgraded completely.
Last year when the WWDC 2012 event ended, Apple CEO Tim Cook promised to have a comprehensive upgrade to Mac Pro . But a year has passed and WWDC 2013 is the best time for him to keep his promise. There are not many rumors about the new model, but Apple will want to completely refresh both the design and the concept of the powerful Mac Pro series. Even Slashgear said that the machine will add colors outside the silver color of aluminum.
Almost certainly the Mac Pro will upgrade the internal configuration with the 4th generation Intel Core i processor with strong Haswell platform. This is also a desktop version of the chip instead of a regular laptop such as a MacBook or a low voltage type for the MacBook Air.
