Adobe has released a video criticising Apple for abandoning Carbon, the programming environment on the Mac, in favour of the Cocoa framework.
The video, below, was posted in February on the Adobe Photoshop YouTube channel and shows Adobe engineers talking about how they had planned to make a 64-bit version of CS5 for Windows and Mac.
"At the WorldWide Developer Conference, Apple announced that they were not going to do a 64-bit version of Carbon. They introduced this other framework called Cocoa," said Adobe's Russell Williams.
"They yanked the carpet out from under the entire industry at that conference," Adobe's John Penn II added.
According to Adobe, the announcement was the first indication that the company got that it would have to undertake a "monstrous re-write" of Photoshop. "Carbon and Cocoa are about as different as Mac and Windows," Williams said.
Some viewers commenting on the video sided with Adobe, with 102 likes to just 4 dislikes. One viewer commented: "Seriously, it's sad how blind Mac fanboys are."
Others, though, took Apple's side. "So? pompous. Photoshop is still an overpriced mess of poorly implanted controls and pointless new features," one wrote.
And others pointed the finger of blame at Adobe for its 'disingenuous' description of Cocoa. "This video is undercut pretty severely by the disingenuous description of Cocoa as if it were something they'd never heard of, when Apple has been urging it's adoption since they first even mentioned Mac OS X a decade ago."
Of course, this is not the first dispute between the two companies to be played out in public -- a spat over Flash boiled over last year, seemingly ending a long-running friendly relationship between the two companies.
