Adobe to delay 64-bit CS4 for Macs

Adobe delays 64-bit CS4

Adobe is already in the middle of developing its Creative Suite 4 series of applications, but Mac users will have to wait behind PC owners in order to take full advantage of their platform, the company has announced. While there is no formal release date planned for any version of CS4, Adobe says that only Windows Vista users will have a completely 64-bit suite at launch, with Mac conversions coming sometime thereafter.

The issue, says Photoshop product manager John Nack, is that many of the programs in the Mac version of CS4 are written with Apple's Carbon code, rather than Cocoa, which is the only option that supports 64-bit processing. "We have to rewrite from scratch," explains Nack. "This makes the cost of the move considerably greater than for Windows. So we will ship 64-bit Windows version first."

It is uncertain which CS4 Mac apps will make the leap to 64-bit at launch, with the exception of Lightroom, which is already written in Cocoa. As such, users can currently download a 64-bit version of the Lightroom 2.0 beta. The main advantage over 32-bit is said to be the ability to address 4GB or more of RAM, which is crucial in programs such as Photoshop and Lightroom, where it can dramatically shrink the time needed to load large image files.

    I'm shocked, I say! To get this type of treatment from Adobe??? This is just so unlike them!

    Hence the 4GB limit...

    ...on MacBook Pros...?

    they didnt think about this when they re-wrote CS3?? was cocoa not available then?

    Here's a great idea!

    How 'bout they fix the issues in CS3? Wow. I like that idea.

    CS3 runs faster in PC virtualization than it does in 10.5.

    How freakin sad is that.

    yea.. it sucks that I cant use the 12 GB of RAM for Photoshop in my MacBook Pro :/

    Mac Pros would be a different story tho...

    Isn't that the excuse...

    ...they gave us when CS3 was so long in coming?

    I would have expected a different lame excuse this time, like the dog ate their only copy of it, or their grandmother died or something.

    Guys get a grip

    If you mosey over to Macworld, you can read about WHY this happened... If adobe is to be believed, they were working on a carbon-based 64-bit CS4 well before WWDC 2007. BUT Apple abandoned Carbon, mandating everyone move development to Cocoa, which essentially takes a complete rewrite of the codebase, "not a trivial task," as they say.

    So calm down! It's coming!

    Actually, the reason they gave was getting it to work in XCode, not Cocoa - big difference. They couldn't have done the rewrite in Cocoa for CS3 because we'd still be waiting for an Intel version.

    It is also true that Apple has abandoned 64-bit Carbon so I'm sure this is the reason for the delay. If Apple has said from the beginning their would not be 64-bit Carbon for Intel, then I'm sure they'd be well along in re-coding it.

    This is a massive job here - the only choices are doing what they are doing or delaying the Windows version to wait for the Mac version just to keep a few people happy. If you ran Adobe, would you do that?

    They should have been developing for Cocoa when they were wasting time on Carbon, Everyone knew that Carbon was a stop gap for people that were developing for Mac OS 9 to buy them time to develop for Mac OS X. Truth is, Cocoa is easier to develop for than Carbon was, Apple gives you XCode for free, and it is by far easier than writing for Windows. CS3 should have been Cocoa to start with. And who runs 64-bit Windows anyway? If Adobe would use the framework in place rather than insist on doing everything their own way it would be more stable, and easier to do.

    Non-Programmers griping

    I just love all these non-programmers that have seen too many keynote speeches being completely clueless about the intricacies of real-world programming. Honestly - how many of you even got past the "Hello World" samples in the thee dev kit? Rewriting legacy code is not trivial. Get a grip. You guys give Mac users a really bad rep.
