Adobe testing optimized version of Flash for Apple's MacBook Air

Adobe's chief executive revealed this week that his company is currently testing an optimized version of Flash built specifically for Apple's newly released MacBook Air.

In an interview at the Web 2.0 Summit this week, Shantanu Narayen said that Adobe is looking to improve battery life on the MacBook Air with a new custom build of Adobe Flash, currently in beta testing in the company's labs. According to Engadget, he noted that battery life performance depends on hardware acceleration.

"When we have access to hardware acceleration, we've proven that Flash has equal or better performance on every platform," he said.

His comments come after testing of the new MacBook Air found that ditching Flash improved battery life by two hours. The new notebook gets six hours of uptime loading pages in the Safari browser, but that dips to four hours once Adobe Flash is installed.

Apple caused a stir in October, when it released its newly redesigned MacBook Air models, but shipped them without the Flash plugin preinstalled. Apple portrayed the change as an advantage to consumers, as leaving the user to install Flash ensures they have the latest version.

Apple and Adobe have been at odds in 2010, in a feud that gained considerable steam after Apple Chief Executive Steve Jobs published an open letter criticizing Flash as old technology that is unfit for the modern era of mobile computers. Apple does not allow Flash onto its iOS-powered devices, including the iPhone and iPad.

Jobs also revealed that Flash is the number one reason for crashes on the Mac platform. For its part, Adobe fired back and said that any crashes of Flash in Mac OS X are not related to its software, but are instead the fault of Apple's operating system.
