According to rumors that happening because of political problems between the CEO of Apple and Adobe, but it is still uncertain. Maybe Apple has another reason, why do not want to use the flash pre-installed on all its latest products.
Reported by Apple Insider, through experiments performed by Ars Technica on MacBook Air 11-inch model found that the MacBook is able to browse for 4 hours with Flash enabled. However, when Flash is turned off, the MacBook is able to survive for more than 6 hours.
Indeed, Apple CEO Steve Jobs explicitly said that all products made by his company will not be supported by features of Flash from Adobe, including the products of their new MacBook Air.
It was recently disclosed by a company spokesman Bill Evans said that Apple will refrain from installing the Adobe Flash platform on all Macs in the future.
However, the MacBook users are still able to get Flash by downloading it via the Adobe website.
