Adobe plans to ship 64-bit Photoshop CS4 for Windows only; no 64-bit Mac version until CS5
Thursday, April 03, 2008 - 09:27 AM EDT

"What does 64-bit computing mean, practically speaking? In a nutshell, it lets an application address very large amounts of memory--specifically, more than 4 gigabytes," John Nack, Senior Product Manager, Adobe Photoshop, writes on his blog John Nack on Adobe.

Nack writes, "It's also important to say what 64-bit doesn't mean. It doesn't make applications somehow run twice as fast. As Photoshop architect Scott Byer writes, "64-bit applications don't magically get faster access to memory, or any of the other key things that would help most applications perform better." In our testing, when an app isn't using a large data set (one that would otherwise require memory swapping), the speedup due to running in 64-bit mode is around 8-12%."

Nack writes, "What's Adobe doing with Photoshop? In the interest of giving customers guidance as early as possible, we have some news to share on this point: in addition to offering 32-bit-native versions for Mac OS X and 32-bit Windows, just as we do today, we plan to ship the next version of Photoshop as 64-bit-native for Windows 64-bit OSes only."

Apple’s Mac OS X Tiger operating system is a true 64-bit environment - April 21, 2005

Nack writes, "The development is frankly bittersweet for us: On the one hand we're delighted to be breaking new ground with Photoshop, and when processing very large files on a suitably equipped machine, Photoshop x64 realizes some big performance gains... On the other hand, we work very hard at maintaining parity across platforms, and it's a drag that the Mac x64 revision will take longer to deliver. We will get there, but not in CS4. (Our goal is to ship a 64-bit Mac version with Photoshop CS5, but we’ll be better able to assess that goal as we get farther along in the development process.)"

Nack writes, "On the Mac Photoshop (like the rest of the Creative Suite, not to mention applications like Apple's Final Cut Pro and iTunes) relies on Apple's Carbon technology. Apple's OS team was busy enabling a 64-bit version of Carbon, a prerequisite for letting Carbon-based apps run 64-bit-native."

Nack writes, "At the WWDC show last June, however, Adobe & other developers learned that Apple had decided to stop their Carbon 64 efforts. This means that 64-bit Mac apps need to be written to use Cocoa (as Lightroom is) instead of Carbon. This means that we'll need to rewrite large parts of Photoshop and its plug-ins (potentially affecting over a million lines of code) to move it from Carbon to Cocoa."

Nack writes, "Now let me be very clear about something: It's entirely Apple's call about what's best for the Mac OS and how to spend their engineering cycles. Like any development team, they have finite resources & need to spend them judiciously. They've decided that Carbon 64 doesn't belong on their roadmap, and we respect their decision. It's up to Adobe to adapt to the new plan."

Nack writes, "As soon as we got the news in June, we began adjusting our product development plans. No one has ever ported an application the size of Photoshop from Carbon to Cocoa (as I mentioned earlier, after 9 years as an Apple product Final Cut Pro remains Carbon-based), so we're dealing with unknown territory. We began training our engineers to rewrite code in Objective C (instead of C++), and they began prototyping select areas to get a better view of the overall effort."

"In short, Adobe has been taking prompt, pragmatic steps to enable 64-bit Photoshop as quickly as possible on both Mac and Windows. It's a great feature, not a magic bullet, and we're delivering the functionality as quickly as each platform permits," Nack writes.

More in Nack's full blog post here.

MacDailyNews Take: Apple CEO Steve Jobs has repeatedly told developers at multiple WWDC events for years now that the future of Mac OS X development is Xcode. Adobe was told to move to Cocoa years ago. They didn't. Hence the massive delay in getting native Photoshop and other apps for Intel-powered Macs.

For years now, ever since the Adobe prefers PCs over Macs incident, we have believed that Adobe isn't as attentive to Mac users as they should be. This latest escapade has not helped to change our minds.

Okay, so let's play along with Nack and pretend for a moment that having/not having Adobe's Flash on Apple's mobile WiFi Multi-Touch platform (iPhone/iPod touch) has absolutely nothing at all to do with this and see what we're left with: Adobe is late on the Mac, their code is old, they had notice to update long ago, but they only made half-hearted attempts to get their code in shape for the future.

Why is Adobe so far behind on the Mac? Because they thought the Mac was dead. But, they were wrong. Dead wrong.

MacDailyNews Note: MacDailyNews has been using Pixelmator (US$59) exclusively in place of Adobe Photoshop since early December 2007 for online graphics. Obviously, we highly recommend Pixelmator. Pixelmator harnesses the full power of Mac OS X. It takes advantage not only of Core Image, Open GL and Automator, it also supports ColorSync, Spotlight and many other Mac OS X technologies. Pixelmator was built exclusively for Mac OS X using Cocoa — and it shows. Pixelmator supports over 100 different file formats and can easily open and save Photoshop files with layers. Plus, it is "demoware," so you can try it before you buy. Read more in our article: Pixelmator gives Adobe Photoshop Elements a run for its money - March 10, 2008

Now lets see if there is some other application that will step in and fill their shoes.

Apr 03, 08 - 09:36 am Comment from: ElderNorm

Adobe is acting just like Palm, a day late and a dollar short is just fine. :-(

Apple has been 64 bit for some time. While Windows has a 64 bit version in Vista, almost no one is using it. So just who does Adobe plan to sell their software to???? All 6 of the Vista 64 users???

Just a thought.

This is absolutely insane. I don't do enough heavy Photoshop work that this would directly affect me, but Adobe really does need to get it's freaking act together.

Apr 03, 08 - 09:38 am Comment from: almux

Right Anim8me2!
Adobe is acting real foolishly! There will be LOOOOOOOTS of other apps, soon, out there to cover up Adobe's lame attitude!

Apr 03, 08 - 09:45 am Comment from: clinicaltechmaster

If Adobe ships a 64 bit version on Windows before the Mac version I will do my best not to buy any Adobe products again. I will use any possible substitutes. There is nothing a Mac user hates more than betrayal.

Apr 03, 08 - 09:46 am Comment from: s

Did Adobe just signed a death sentence for Photoshop? Aperture, Pixel and Iris seem like a possible replacement for the raster image editor. I just need someone to come up with an Illustrator replacement to get me out of Adobe creative suite.

Apr 03, 08 - 09:51 am Comment from: Mr. Reeee

It seems like Adobe is pulling a Quark. Quark didn't do a serious upgrade of QuarkXpress for years and guess what? Adobe stepped in and cleaned their clock with InDesign.

Now the shoe is on the other foot, as they say.

Apr 03, 08 - 09:51 am Comment from: Daniel P

I do understand that Adobe had no desire to completely re-write Photoshop from scratch just, well, because. I'm sure no one here would be impressed if Microsoft tried to force everyone to shift to their new Office file format (let alone having to rewrite everything to do so). I'm leaning towards Adobe here. Apple shouldn't have just canceled carbon so suddenly and Adobe should not be blamed for not getting any warning from Apple.

Apr 03, 08 - 09:54 am Comment from: Gone Nuts

Adobe and Apple are more competitors than collaborators these days. The more features that go into Aperture or Logic Pro, or Final Cut, the more Adobe stresses out. This is no different than the media companies relationship with Apple.

Just go on the user forums for Apple and Adobe and you'll hear this attitude through their customers. Aperture users hate Adobe, and Photoshop/lightroom users hate Aperture. As this is an Apple forum, we hate Adobe.

Apr 03, 08 - 09:54 am Comment from: bob

photoshop should have been redone in cocoa when they took there time over a universal version, they should have used that time better, just lazily still using the classic code still.

Apr 03, 08 - 09:58 am Comment from: jtc

Being a heave adobe suite user... this upsets me. I was really hoping I could allocate a lot more than just 3GB of ram in photoshop within CS3 but they didn't make it 64 bit so I "assumed" it would be in CS4. Sadly I shouldn't assume as you know the saying goes... Maybe they will realize that REAL designers use a MAC not some shitty windows OS.

Apr 03, 08 - 10:01 am Comment from: Mr. Reeee

I've about had it with Adobe. Not only are they late, AGAIN… almost 2 years for Intel/Mac versions… but their upgrade fees are pure gouge-fests. They just want to squeeze Mac users for more cash. The heck with them. I'll wait until CS5. I usually skip a version anyway.

When I finally decided to buy the CS3 upgrade I had 3 FULL licenses to Adobe CS apps: Photoshop, Acrobat pro and Freehand. After finding no info on a 3-product upgrade price, I called Adobe. So, owning THREE license to separate products got me the FULL upgrade price as if I owned only ONE.

Now THAT SUCKS!!! (almost as bad as Acrobat Pro 8's interface!)

If there were any better alternatives to Photoshop and Acrobat Pro, I'd jump! Unfortunately, I've got to stay "compatible".

Any Suggestions?

You have already been told in MDNs take that Apple gave Adobe plenty of notice over their future roadmap. Open your eyes instead of behaving like some simple minded horse.

Apr 03, 08 - 10:06 am Comment from: GerberG8TR

Wow — Adobe is really dropping the ball. Better watch out Adobe, or Apple will “Final Cut” you... again! (remember Adobe Premier?)

Apr 03, 08 - 10:07 am Comment from: HMCIV

Adobe will catch up. There's plenty of demand for Photoshop so they'll get with the times. Better late than pregnant.

adobe is funny... stupid funny


they are obviously a bloated bureaucratic company ran by old guys with their ties tied too tight

Adobe owes it's existence to the Macintosh.
One other thing Adobe hates is the PDF functions built into OS X.
When my Windoze friends see how quick and easy it is to save & email something as a PDF their jaws drop.

Apr 03, 08 - 10:14 am Comment from: Macaday

OK with me, Aperture 2.1 is doing a fantastic job for me these days...

Apr 03, 08 - 10:17 am Comment from: MCCFR

Miserable, lying, lazy, rat-fscking b**tards

Apr 03, 08 - 10:18 am Comment from: WindozeKiller

I just hope this is the final straw and Apple FINALLY just buys Adobe and slowly phases out windoze versions. It's not just THAT. Buying Adobe gives Apple control of the PDF format and Flash. They could then end the abomination that is "flash video" once and for all.

This is LONG overdue.

Apr 03, 08 - 10:19 am Comment from: MacRaven

Apple put Adobe on the map. This is the effort they put out for Apple in return. Adobe crawls in bed with The Dark Side and snuggles up.

I've been disappointed in Adobe for the last 5 years, but what's the alternative? Quark? Adobe is the lesser of 2 evils.

Apr 03, 08 - 10:19 am Comment from: pastrychef

Apple should just buy Adobe and get it over with...

Apr 03, 08 - 10:22 am Comment from: flappo

pixelmator is crap , i had it and it was buggy slow and useless

now i've got pe6

which is

buggy , fairly rapid , and ok

what IS odd is the save for web page is exactly the same as the pe2 screen

!!??!!

Apr 03, 08 - 10:24 am Comment from: Skeeter

Just another reason to continue to look at and support both open source and alternatives to any Adobe product!

Apr 03, 08 - 10:25 am Comment from: peragrin

Actually this is a pure carbon/Cocoa issue. Adobe should have upgraded their entire system to the new Cocoa when the G5 PowerPC's came out. Instead they stuck with OS 9 technology for Mac's. if Adobe had switched to Cocoa back then the transition to Intel would have been quick and easy.

Adobe has learned that the hard way.

Apr 03, 08 - 10:26 am Comment from: Take 'em over

I think it's a good thing that Apple haven't got this take-over 'mania' which seems to infect so many successful companies.

But ... couldn't this be the exception (which proves the rule)?

Apple could make the Adobe shareholders an offer they couldn't refuse.

Apr 03, 08 - 10:27 am Comment from: Tom V

@ jtc

The solution to your problem is installing a small high speed scratch disk. I am a heavy Creative Suite user and I found that adding a western digital raptor 10,000 rpm 36gb scratch disk made photoshop and illustrator run way better. I also run 6GB of mem on my Mac Pro.

Hell, I'm perfectly happy that I don't need to buy CS4 now! CS3 cost a pretty penny and now I will get more use out of it before I have to upgrade again.

I personally feel CS3 runs great... Far better than previous version.

Apr 03, 08 - 10:29 am Comment from: Reality Check

Fark Adobe, at work I suffer through using an HP desktop and the IT boys recently put the latest "Free" viewer. and BY free I mean free to hog every resource the box has, free to crash when printing, free to be utter trash. I will NEVER put an Adobe product on my mac. They suck..

Apr 03, 08 - 10:29 am Comment from: BSOD

I have had 64bit Vista on a system for about a year now. nVidia driver lockups are quite common. - Strike 1

Companies are not adapting Vista, let alone Vista 64. - Strike 2

64bit XP is quite stable, but will soon be taken off of the shelf. - Strike 3

Apparently the people at Adobe have not been using 64bit Vista for very long. They have not been paying attention to market trends, And they have not paid attention to product announcements. Stupid, stupid, stupid.

Apr 03, 08 - 10:33 am Comment from: almux

@ Take 'em over
Well Adobe is a heavy and old machine wich would cost a big lot of money for what it realy worth.
There are younger, swifter and much more innovative teams around the world to work with.
If anything must be rewriten in Cocoa... let new brains put it together and things will go smoother for Apple.
Thats my guess...

Apr 03, 08 - 10:34 am Comment from: ChrissyOne

MDN, your take is right on, and when this came up last year, and it seemed to be big news to the developers that Carbon was basically EOL'd, I was completely shocked at what I was hearing.
I knew, and I thought everyone else did as well, that Carbon was not long for this world, and I never imagined that there would be a 64 bit version, even years ago when OS X was new. It never crossed my mind.
But Steve's announcement last year was evidently Big News to everyone else, and there was quite a big scene about it. It seemed like the news came out of nowhere but they should have bloody known.

{sigh}

Oh well. I only really use Lightroom any more anyhow.

-c

P.S. Oh, and yes, this has absolutely NOTHING to do with Flash on the iPhone. I promise.

Apr 03, 08 - 10:36 am Comment from: Macs King

I've been pissed at Adobe for years. Recently, their support people in India ran me all around. It took 3.5 hours and mulitiple phone calls to get my CS version of Photoshop "authorized".

The first Adobe support person told me I must update that my software was too old. I asked for his name and I. D. number. He asked "why do you want that". I told him "so I can tell Adobe in USA the name of the person who said I can't install the $700 software I paid for".

Eventually I got authorized. At one time, I maintained licenses to all Adobe software products. Now we're down to Photoshop only.

I am hoping developers will add effects and text to Aperture. Then I can kiss off Adobe for good.

I had been considering updating to the premium Web bundle, but after the runaround with the India support guys, I decided to rethink the plan. I DON'T NEED TO AUTHOR FLASH!

Apr 03, 08 - 10:36 am Comment from: Radius

I am going to be trying out Pixelmator, thanks to this article. $59 for a Photoshop Elements replacement custom made for OS X? That is worth at least a try. Plus, I would like to support these guys.

Apr 03, 08 - 10:37 am Comment from: ron

Adobe is a mud hut. Apple should rain on them or buy them.

Apr 03, 08 - 10:41 am Comment from: DLMeyer

I've been told that Windows-64 does not run Windows-32 apps natively - one of the reasons Win-64 sells fewer seats than OSX. So ... what market are they going for? My guess is this will be their 64-bit Public Beta that the users will be paying full price for. They want to make sure their code is at least "good enough for Windows" before they unload it on the rest of us. I expect we'll all see an interesting story unfold here - either the Win-64 market will step up to embrace CS4 or Adobe will shift gears and get CS5 ready much earlier than expected.
MDN: yeah, this version was better than the one I passed along.

Apr 03, 08 - 10:42 am Comment from: Buster

Screw Adobe. Elements sucks and I haven't upgraded beyond CS2. I don't need 64-bit but I feel for the people that do.

Apr 03, 08 - 10:42 am Comment from: Follower

Can anyone verify what Nack says about Final Cut Pro (which, tangentially, I just saw during the end credits was used to edit No Country for Old Men) still being Carbon-based? Is it likely that the pro-est of Apple's Pro apps is still using what peragrin termed "OS 9 technology" ...?

Apr 03, 08 - 10:46 am Comment from: ChrissyOne

@ Macs King

I feel your pain. I can also tell you that the support situation is getting fixed.

Apr 03, 08 - 10:51 am Comment from: Turbo

Does anyone know: Does Pixelmator do animation (like ImageReady) as well?

Apr 03, 08 - 10:55 am Comment from: mr_matalino

and to think that there have been calls for Apple to buy Adobe for years...

a junk company who doesn't know what their customer base uses...

Apr 03, 08 - 11:06 am Comment from: Jordan

Online graphics?! What online graphics? MDN could use Microsoft Paint to create the few puney graphics on this site.

Go Photoshop! And Lightroom! And Flash!

Apr 03, 08 - 11:09 am Comment from: Adobe ExPat

Apple should do a hostile takeover of Adobe. Then kill Flash on all platforms. Then kill Premiere on all platforms. Then kill Photoshop on Windoze platform. That would free up enough resources to get a Mac version of Photoshop written in Cocoa ahead of schedule. Problem solved.

Apr 03, 08 - 11:09 am Comment from: Cubert

I tried the Pixelmator demo and it was buggy as hell. It does some things in a way that seems counterintuitive to me - or maybe I am just used to the Photoshop way.

Apr 03, 08 - 11:10 am Comment from: Rob

Quark went through the same thing. They also thought Apple was dead. They had a commanding lead in DTP, over 90%. When it took them over 3 years to come out with a OS X version, they lost almost 45% in less than 2 years. I'm almost glad this is happening. It will give competitors a leg up and create more competition to Adobe's Microfoftian tactics.

Apr 03, 08 - 11:15 am Comment from: Cubert

@DanielP,

"I'm sure no one here would be impressed if Microsoft tried to force everyone to shift to their new Office file format"

Uhhhhh......that is happening. Look in the news.

Adobe sucks.

I'll never spend another dime of my money on their shiite.

Apr 03, 08 - 11:23 am Comment from: Jubei

If a developer doesn't want to fully support a platform, then the writing is on the wall. Excuses given is lie. Since they were given enough time and early notices to move their development tools to properly support the Mac. They didn't. So kids, Adobe is sleeping with the enemy and that enemy will swallow them, chew them up for all their worth, then spit them out. They'll come back to Mac users and beg us to buy their crap. No thanks. I hope by then, either Apple develops a better app or does an entire creative suite. Adobe creative suite is a joke. They are milking customers with several versions like Vista.

Apr 03, 08 - 11:24 am Comment from: Cubert

@marco,
"When my Windoze friends see how quick and easy it is to save & email something as a PDF their jaws drop."

Mine too. Their only option is to print it out or copy and paste the whole thing onto another document. Sometimes saving as a HTML file doesn't work because it is a secure site, but, saving as a PDF always works and is easy as hell. I keep all of them in a web receipts folder and then delete them when they are irrelevant any more.

Apr 03, 08 - 11:32 am Comment from: effwerd

I can understand why they're so slow, rigor mortis makes moving difficult. It takes a while for the undead to get adjusted.

Apr 03, 08 - 11:45 am Comment from: ndelc

Frankly, I don't really care if they get the Mac version out in 64bit at the same time as the Windows version, except in principle. I'd be happy if they'd just fix the numerous bugs in the CS3 suite apps. If I hadn't paid so much for it, I'd go back to CS2. I mean, what is PSCS3 doing when the beachball spins for several minutes for no apparent reason a few times each day? It makes no sense. I call it a coffee break, but it's so annoying! And really, could it be that difficult to fix InDesign so that it remembers that I want my default measurement to be inches? Come on! I used to love Adobe, and I want to love Adobe again, but they're not making it easy.
