Mac OS X 10.6 to drop PowerPC support?

While everyone focuses on the iPhone next update, a new rumor posits that Apple will already have a new version of Mac OS X available for testing in early form at WWDC, with its actual launch appearing as early as next year's Macworld event.

Similar to Mac OS X 10.1, however, the release would more closely resemble a maintenance release than a complete overhaul. The primary change would be a complete transition to an Intel-only, 64-bit platform that drops PowerPC support, pushing developers to code only for the x86 architecture at the heart of all Macs released from 2006 onwards.

Expectedly, Apple has refrained from discussing any of its post-Leopard plans to date. The company has nonetheless dropped early signs that it may be preparing for the new release, with reports of a small 10.6 reference surfacing in the latest build of the iPhone's software development kit.

I doubt it. And it definitely won't be 64-bit only since the first gen Intel macs only had a Core Duo which was a 32-bit chip.
#1.1 PsykX on 04 Jun 2008 - 14:44
Why do you doubt it? If I had a PowerPC, I'd seriously upgrade for this version, which will come out in like 2 years. PowerPC is getting quite old in fact.

Now, of course it will support 32-bit, but maybe it will be more focused on 64-bit (I never understood the 64-bit part in Leopard actually).

I don't know where people get all this info about 10.6 though. Just because it's written "10.6" in two places now, they say it will only be a maintenance release rather than an overhaul. Care to explain?

It's not Neowin's fault for this article, but I really don't like it.
#1.2 Lasker on 04 Jun 2008 - 14:44
I agree too, but not one knows exactly the Apple plans for 10.6 until the release of the first beta.
#1.3 Julius Caro on 04 Jun 2008 - 14:59
I dont really understand how the 64-bit on the macs work either. I've read that the kernel is 32bit, even though there's 64-bit code support?
#1.4 MrA on 04 Jun 2008 - 15:04
I doubt it because of several reasons:
1. There's still a significant user base of PPC macs.
2. The last PPC mac to ship was the xserve G5 in late 06. That was only 2 years ago. It's too soon to kill support for it. Doing so would **** of a lot of users.
3. Historically, the requirements of OSX releases haven't jumped significantly. Killing PPC support would represent a huge (and unnessesary) jump in system requirements.
4. The effort involved in maintaining a second architecture isn't as high as some people may think. A clean code base makes it easy to maintain multiple architectures. Look at Linux and *BSD. Having to support multiple architectures helps to promotes a clean code base.
#1.5 bluarash on 04 Jun 2008 - 15:06
It won't be 64bit only. The entire first run of production machines (iMac and Mac Books) were Core Duo. Neither Microsoft or Apple is going to be exclusively 64bit (for at least a decade) due to software and hardware compatibility (drivers). I can not speak for Apple... I don't think anyone can besides Apple, but I would be hard pressed to believe they plan to end support for the Power PC (though in truth it has been suggested before even 10.5 was released). They supported the G3 for a number of years (after it was dated... though that was the same architecture).

If I had to guess, I would assume that Apple will offer a 64bit kernel in the 10.6 release and will offer PPC support as well, but will make significant changes to their developer tools to make a shift over to being Intel exclusive.

Historically, Apple has regularily ****'d their users everytime they want to do a major upgrade or save some money.
As for the effort involved, I think Apple is aiming for 0 effort, so 'not much' would be way too much for them.

Apple probably won't make their first 64-bit OS be 64-bit only =P

Don't forget Apple makes most of it's money from selling hardware. Surely they get some money from sales of OSX but don't for a second think it's their biggest cash cow. Apple is a hardware company first and foremost If they can kill off PowerPC and have some people upgrade to their latest Core 2 Quad Desktops instead you think they would say no? Uhuh.. that's what i thought

In fact, Apple always did nice and smooth transitions from what I've seen so far. They always worked hard to make these transitions as smooth as possible. Now I am thinking about the PowerPC to Intel transition specifically, but also Carbon to Cocoa. They had to do this "extra work" to get things compatible you know, like create this whole Rosetta emulator to support older apps, etc. etc.

Also, in two years, you PowerMac or whatever it was called will probably
1. be old
2. be 25% as fast as what we see now on the market
3. won't be able to handle these new heavy applications with all the new sexy graphics and everything

The only good thing maybe will be your memory.

Would users of the current Leopard get a free upgrade?

Do you had a free upgrade from Tiger? NOT
#2.2 PsykX on 04 Jun 2008 - 14:45
Never. It's a .x release, so it's like 130 bucks.
Now, I know you're shocked because Leopard went out at the end of October, but this 10.6 thing is really not happening right now, trust me. They didn't even finish patching Leopard, so it'd be stupid to release another version.
#2.3 Galley on 04 Jun 2008 - 14:58
If it doesn't add any significant features, then it may be free. 10.1 was a free upgrade.
#2.4 sphbecker on 04 Jun 2008 - 15:24
10.1 was free because 10.0 was a POS.
#2.5 hapbt on 04 Jun 2008 - 15:51
feel the apple love!
gotta love paying for your open source OS upgrades on your overpriced hardware that already included the price of the OS!
#2.6 PsykX on 05 Jun 2008 - 02:35
Who told you Mac OS was open source?

Is Mac OS really that expensive in this market? Compare with Windows yourself. And compare apples and apples, meaning the ultimate vista versus the ulti... errr, wait, there is just one OS X.

I agree that Macs are quite expensive, but it's been told a lot of times. Take that whole package in a Mac, separate every single component/feature that a Mac include, and compare with a PC with the exact same configuration and the exact same components/features. You'll see that Macs are actually quite well priced, but then again you have to add a little price just for the design (as you would do with a PC, if you want a killer case)
#2.7 sphbecker on 05 Jun 2008 - 14:45
Mac OS's kernel is based on an open source project, but the bulk of the package is closed source.

If you want to compare the cost of OS X to the cost of Windows you need to also consider the life-span of each version. OS X and XP came out about the same time. Sense then Windows users have had to pay for one upgrade and Mac users 4 (not including this upcoming release). Granted, the XP/Vista interim was a few years longer than normal, but historically MS operating systems stay current about twice as long as Apple's.
#2.8 eilegz on 05 Jun 2008 - 18:12

#3 vetneufuse on 04 Jun 2008 - 14:45
I wish they would drop PPC support... PPC on a mac is a dieing breed especially with the much better hardware they how now, and the fact you can natively run x86 and x64 based OS's ontop of it without emulation... but anyways how could they go 64-bit only? their first CPU's where 32-bit only when they took the Core line... they didn't have 64bit instruction sets in them originally, that came in the form of Core2

I hope they don't but it wouldn't surprise me if they dropped support and [typically] expected people to put more money down.
#5.1 PsykX on 04 Jun 2008 - 14:55
But when you know your computer is more than 3 years old, and you can get a killer design and a new computer that is like twice or thrice as fast... I don't know. I mean, yeah it sucks for PowerPC users but it has to happen someday.

PowerPC? Ha ha ha... Mac users are so [insert colorful adjective here] about upgrading there couldn't be many PPCs out in the wild anymore. And the ones that are will have to make do without the newest service pack for OS X.

Just like "classic", Apple gave their cult customers time to transition and then ended support for Classic. In much the same way, they could announce and end of support for PPC, give customers a chance to transition, then, drop support from OS X. Not a huge deal.

I think it would make sense for them to drop it. 10.6 should launch around the end of 2009 (along with windows7). by then, most PowerPC macs will be around 5 years old.

Now, if they were to drop intel 32-bit, then i would be ****ed. My macbook would only be three years old by then and just barely out of apple care support.
#7.1 bobbba on 04 Jun 2008 - 17:21
OS X 10.6 rumored to hit alpha next week and be released January 09. source

Apple have stated that they are aiming for 12-18months for OS X releases.

#7.2 sphbecker on 04 Jun 2008 - 20:28
most PowerPC macs will be around 5 years old.


The first Intel Mac was sold in 2006 but it wasn't until August of 2006 before the entire product line was available with Intel processors. If this new OS without PPC support comes in early 2009 as bobbba stated then someone with a ~2.5 year old PowerMac would not be able to install it.
(1 reply) #8 Chicane-UK on 04 Jun 2008 - 15:49
I can't see 10.6 happening any time soon. Leopard really has only just come out. Needs to be two years minimum IMHO. Tiger ran for over two years - but admittedly previous versions came out very quickly. Wonder if Apple will go back to that sort of release schedule?

Would stand to reason they might discuss it at this WWDC but even then I doubt it.
#8.1 acies on 04 Jun 2008 - 16:21
Why does it NEED to be 2 years minimum?? As the article says it wouldn't be a big overhaul.

#9 jamesyfx on 04 Jun 2008 - 16:28
Well they don't make computers with PowerPC's anymore. Makes sense to me.

If you wanna use 10.6, get better hardware. That's the message, basically.
#10 +CelticWhisper on 04 Jun 2008 - 16:36
I'd sure as hell be done buying Apple products if they did. My G5 Quad is only 2 years old and considering that a 7-year-old G4 can boot Leopard, it would be a really heinous move for them to axe PPC support.
(3 replies) #11 z0phi3l on 04 Jun 2008 - 16:41
If Apple pulls it off, which I hope they do, MS will copy them soon after, and yes 32bit needs to hurry up and die, 64bit is the now and future and people on both sides need to get with it and face reality, that will also force the hardware manufacturers to finally get off their collective asses and implement proper 64bit support like they should have been doing for a few years now.
#11.1 +CelticWhisper on 04 Jun 2008 - 16:44
I wouldn't mind them dropping support for 32-bit PPC and maybe, MAYBE 32-bit Intel. But if they're forcing 64-bit support, then they should keep 64-bit PPC around for the PMG5s, iMac G5s, and XSG5s out there that are running a 64-bit arch.

They can't drop 32-bit PPC support without dropping 64-bit PPC support, since they have no 64-bit PPC support (just PAE-hacks to make it sort of kind of allow 64-bit addressing). There is no 64-bit Mac kernel, no 64-bit Finder or other apps. They just have some "64-bit aware" libraries that they claim means they support 64-bit.

Interesting. I should learn more about how Apple codes their OS. I must have assumed it was something similar to the universal binaries for application software wherein you could have 32-bit code and 64-bit code in one package. Dunno why I thought they could get away with that in a kernel, though.

If that's the case, maybe they'll go the Vista route and have a PPC/i386 version of 10.6 alongside a PPC970/x86_64 version.

Hmm. Which Macs are you trying to run it on? My G5 Quad was the highest-end PPC Mac they had before the Intel switch but I've seen some older PPC Macs running 10.5 alright. Not sure if maybe there are some model-specific quirks or some such that are causing a slowdown, but of course your mileage may vary.

Are these iMacs, Power Mac towers, notebooks...?

It really wouldn't be that much of a reach for Apple to force non-Intel users to have to upgrade when they get around to OS 10.6. That's been their pattern throughout the evolution of OS X and they never seem to have a problem dropping users of older equipment as they advance the OS. Yeah, it'll probably be in 2009, but I wouldn't be surprised at all.

I had a couple of beige G3 boxes that got left behind when they went to OS 10.2 (Jaguar) and my 600 mhz G3-based iBook and my G4 (400 mhz AGP Graphics based) were able to run 10.4 (Tiger) without any issues. Leopard won't run on my iBook at all and I'd have to replace the processor and upgrade the memory in order to run 10.5 (Leopard) on the old G4 box. Heck, you can't even run Classic apps under OS 10.5 (especially since the OS 9 apps were never meant to run on intel-based hardware).

I could justify buying an iMac, but that's the pattern that Apple expects it's users to go along with. Every few years you'll have to buy new hardware in order to go to a new version of the OS.

Nobody seems to take Apple to task when they make these kind of moves - their users tend to just nod and accept the fact that they're gonna get screwed from time to time. That's the price we pay for being Mac fanboys.

The same thing happened to the old Motorola-based Mac users years ago. Now after years of having Apple sing the praises of the PowerPC chips over Intel (until they made the switch and discovered 2-4 times performance improvements) it's not gonna be that much of a shock when they drop the PPC-based Macs as well.

#18.1 dp123 on 05 Jun 2008 - 08:49
A sane post so I'll post my comment in reply:

Something to consider: this could also be a ploy to move more developers firmly to 64-bit Cocoa -- sometimes they (cough-Adobe-cough-Microsoft) can be reticent. Have a nearly 64-bit clean, Cocoa-only OSX early in 2009. Release it only on new gear -- maybe even maintain Leopard as an downgrade option since that's become popular ;-) -- damn, that would be a funny bit of photocopying, and maintain 10.5 for older hardware through the year or until the next release. If it shows a great deal of improvement, many users and many developers will embrace it. Those dependent on older hardware or apps will stick with their existing gear and won't have much to complain about if there's little feature disparity besides performance improvements.

However the timing and pricing works out (this is still a rumor however accurate it is), this has always been planned and foreseeable. 68000 procs > PPC > x86 ... Classic > Carbon > Cocoa.

As you (and I) know... we've lived through it, all of it was quite manageable if you didn't get hysterical.
#18.2 ikyouCrow on 06 Jun 2008 - 13:04
this is exactly what i was thinking when i saw the headline. i wonder what took them so long?

Apple has a long standing tradition of forcing upgrades as a way of saving themselves extra trouble. look how quickly after the first "transition" they dropped support for 68K systems.

and PowerPC... anyone else here remembers the "propaganda" surrounding the technical superiority of the PowerPC architecture? then to have Apple switch and notice huge performance gains? i'm sure if you found an archive of the old Apple site, they probably even used the same processors for the comparisons.

expect similar propaganda for Intel processors and how much power consumption they save and how much cheaper they are and how many chainsaws they can juggle.

it was inevitable; finally just happened.

I'd say the PowerPC Macs probably couldn't run the latest version of OS X anyways. Why continue supporting them?

Meanwhile, you can still boot Windows XP SP3 with an old Pentium 60 Mhz CPU.
Not very fast, mind you, but it will actually run. Hell, you can underclock it to 8 Mhz and enjou a 10-minute boot time. :lol:
#20.1 eAi on 05 Jun 2008 - 07:10
Well, if you'd say that you'd be wrong. PPCs from many years ago can still run Leopard, and often it'll run faster than whatever OS they came with, in my experience.

Quite. Leopard runs better and faster on a Dual 2.5, 2.7 and Quad 2.5 than what Tiger did. I can even say this for my Dual 2.7. I can't see any reason why it would not be the same for the Dual 2.0 and 2.3 models.
#20.3 ikyouCrow on 06 Jun 2008 - 18:05
not entirely true.

a buddy of mine runs Leopard on his G4 PowerBook and it's pretty peppy.

Apple just wants to get a break from PPC support; if they can phase them out, they won't have to bother with keeping PPC stuff in Xcode.
#21 Julius Caro on 05 Jun 2008 - 08:34
They should recall all the 'Core' (as opposed to Core2) "mactels" and go 64-bit only
