I wouldn't compare it to dropping support of a P4. I would compare it to dropping support for 32-bit processors in general. P4 is a processor, not a platform :p

But I see your point though. I think we should wait and see what Apple is planning. Nothing official has been announced regarding PPC support.

Intel Core Duo is 32bit. G5s are 64bit. They're dropping the PPC platform.

Cara - so you work for Apple? When did you get a job there? I can remember you from way back in the early days of Neowin.

2 years, 2 months. : winks :

As for dropping PPC, as I've said before, keep in mind that even the last G5's are now reaching EOL (3 year AppleCare will be up be Jan of 2010 at the last of them) so it's about time to let PPC go and move forward. :) Yes, the G5's are awesome chips but they are now several generations old, you can't build the future while dragging the boat anchor of old technology behind you. Innovation comes at a price.

I think you missed my point.

Coding for the 64-bit platform is very different than the 32-bit platform, same as coding for the PPC compared to the x86 platform.

Dropping PPC support for OS X will be as big as dropping 32-bit support for Windows. The P4s are really outdated, PPC processors are not.

i think it's a smart move to drop the PPC line (just like Windows 7 SHOULD be 64bit only....but it won't)

now too bad they can't move to 64bit only (since the first intel mac were 32bit :pinch: )

Well I would also assume it's because of the existing drivers 32-bit drivers. Wikipedia explains this well:

Because device drivers in operating systems with monolithic kernels, and in many operating systems with hybrid kernels, execute within the operating system kernel, it is possible to run the kernel as a 32-bit process while still supporting 64-bit user processes. This provides the memory and performance benefits of 64-bit for users without breaking binary compatibility with existing 32-bit device drivers, at the cost of some additional overhead within the kernel. This is the mechanism by which Mac OS X enables 64-bit processes while still supporting 32-bit device drivers.

That's how Leopard just ships in just one version, but has full support for both 32/64-bit drivers and applications out of the box.

Proof in the pudding:

As you can see there, the Xcode universal binary supports 4 architectures right there (32-bit PPC, 64-bit PPC, 32-bit x86, 64-bit x86). But interestingly enough, Xcode is only one of the few x86_64 Apple applications in Leopard. Others include Chess (lol?), AU Lab, Quartz Composer:

I'm predicting that lots more first party applications from Apple will now contain both the i386 and x86_64 binaries in Snow Leopard.

Take it as you will, but that Orchardspy.com site says the following:

While Snow Leopard is said to be fully 64-bit, as the screenshots show it will work on 32-bit (Core Solo and Core Duo) Intel processors. It will not be compatible with PowerPC, although Orchard Spy has learned that Apple is at this point continuing to churn out builds for PowerPC?but only internally.i>

So who really knows at this point until Apple says so themselves.

What about a 32-bit PPC build?

Not to my knowledge. I believe they are phasing out the G4 series, it was started with Leopard being 867mhz+, I think that 10.6 will have no support for non-Intel 32-bit when it ships.

As long as it doesn't get split 32-bit/64-bit like Windows does, because that's one big pain in the butt.

Wouldn't make much sense to release a separate 32-bit/64-bit version of Snow Leopard as it'd be a step backward from Leopard, which supports both 32-bit/64-bit in the same release.

It was sarcasm. :p

Apple has no intentions of releasing 32bit and 64bit versions of OS X, all versions going forward will be 64bit with 32bit emulation for Intel Core Duo and Core Solo processors. I do not know if the final decision has been made regarding 32bit PPC.

Emulation? Like Rosetta? I'm not seeing that.

I would think they would be running it natively through the 32bit kernel like they are now which can still take advantage of 64-bit applications and processes. I wouldn't think they would only support just one archicture (x86_64) so soon--that would break compatibility all the existing 32-bit drivers. (like how it is on Windows)

The Activity Monitor screenshot shows it right here where the 64-bit and 32-bit processes are running side by side, where I would assume through the 32-bit XNU kernel:

giga, all good points which I'm going to try to get answers from the dev team on without raising too many flags that I'm asking. : winks :

Edit: Keep in mind those are Intel 32bit processes, I think they are only pulling PPC 32bit support...

Obsolete MY ASS. I hope that's a misprint or they change that requirement real soon. My G5 Quad is anything but $3500 worth of "obsolete" and there are a lot of people (not to mention institutions - libraries, schools, other organizations with limited budgets for IT resources) that are still running PPC-based systems for purposes that DO NOT NECESSITATE upgrading hardware.

This G5 may well be the last Mac I ever buy if they seriously are going to remove PPC support altogether. Leopard runs on goddamn G4s, and one year later they want to remove the entire architecture?

F**k you, Jobs. You and your "forward thinking goals" can blow me. At least I know Linux will always be an option.

Easy there killer. No one is forcing you to upgrade, besides Snow Leopard has no new features, 10.7 will be when you should bitch. Your acting like OS X is suddenly going to fail, Leopard is very good and so is Tiger. Quit throwing a hissy fit because you can't get the latest software.

If they drop PPC support (can't see why they would, binary size has little to do with install size), then it does screw over PPC users.

Sure leopard will still work, apps that require 10.6 won't. Leopard is great and all but you can't do everything with the base install, you need 3rd party applications for that.

Remember back when Apple killed Classic with 10.5...even for PPC users who technically could still run it... This was done for the greater good and to drive the transition to OS X... Killing 32bit PPC drives those old users to get onboard with Intel or a 64bit G5..

Classic was for software only, and what do you mean by driving people to use OS X?.

I'm not going to spend $1,000+ for a new computer just because they don't want to support my current one (for no other reason than not wanting to support my current one)

Edit: If there's a technical reason for dropping PPC, then fine, so far I haven't heard a valid technical reason (all the reasons I've heard haven't been valid and a majority make no sense)

Which system do you have if I might ask? :)

Classic was the previous generations environment that was dragged along for quite some time, Apple decided to push the last few people using Classic to adopt OS X Coding and Applications by eliminating the option of using Classic. I have G4's but even I have to admit they are all very old and have had a killer life cycle.

They've just announced it, and it already has some new feature.

What makes you think they aren't gonna have larger new features by the time it is released?

    • A roguelike and a 4X strategy game are free to claim on the Epic Games Store by Pulasthi Ariyasinghe The final leg of the Epic Games Store's mystery giveaways promotion just landed, and it brought along two more games to keep. Last week's Lonestar and Calico giveaways have now been replaced with copies of Rogue Waters and Songs of Conquest to claim for PC gamers. As always, the game is yours to add permanently to your Epic Games Store library within the next seven days. Diving into the games, Songs of Conquest is developed by Lavapotion. This is a turn-based 4X strategy experience that has players making tough decisions and participating in tactical combat while also managing their kingdom. "Songs of Conquest is a turn-based strategy game inspired by 90s classics. Lead powerful magicians called Wielders and venture to lands unknown," explains the developer. "Wage battles against armies that dare oppose you, hunt for powerful artifacts and expand your territory. The world is ripe for the taking – seize it." Meanwhile, Rogue Waters comes from developer Ice Code Games. This rogue-lite experience has you taking the role of Captain Cutter as he commands his ship and crew through procedurally generated encounters. You'll be recruiting and training crew, use sea creatures, and battle with other ships and pirates. "Set sail as Captain Cutter, a pirate caught in a deadly struggle for power and vengeance," adds the developer. "Navigate dangerous waters, unleash mythical sea creatures, and outwit enemies as you chase legendary treasure and confront dark secrets." The newly available Rogue Waters and Songs of Conquest giveaways on the Epic Games Store are set to run until June 11, giving PC gamers seven days to claim the latest offer. Once this closes out, a new freebie will take its place on the same day, which is slated to be Warhammer 40K Speed Freeks. Don't forget that mobile gamers can check out the Epic Game Store's weekly giveaways on Android and iOS to grab a freebie there as well.
    • Still using Classic Outlook? Microsoft highlights 15 reasons to switch to New Outlook by Usama Jawad As many of you may know, Microsoft has been trying to get customers to ditch Classic Outlook in favor of New Outlook for quite some time now. To that end, it has added numerous capabilities to the latter, including PST features, and it is working on several more, such as a unified inbox. However, customer response has been a bit lukewarm so far, with many considering the New Outlook to be "hot garbage". Now, Microsoft has highlighted 15 features that users can leverage in New Outlook in yet another attempt to get customers to migrate. Although not all of the 15 capabilities are exclusive to New Outlook, in fact, most of them are available in Classic Outlook as well. But Microsoft hopes that this combination of familiar and fresh features will be able to attract existing users as well as new ones. For ease of readability, we have summarized the 15 features below: Pin an email: This makes it easier to track important emails Snooze an email: You can temporarily snooze an email thread for a specific time frame until it becomes relevant again. This can be very useful in scenarios where you don't feel like actively following a thread or simply want to follow up on a later date Add multiple categories at the same time: You can assign multiple categories to an email through a single, simplified interface Sweep: As the name implies, you can define automated move processes on your inbox to declutter it, rather than cleaning it up manually Schedule send: Does exactly what it says on the tin, and can be useful when accommodating recipients in different timezones Simplified folder sharing: The sharing process has been simplified so permissions are automatically applied on parent folders Follow a meeting: This is an RSVP option that lets people know that you won't be able to join the meeting but would still like to access a recap Save calendar views: You can save different views for the calendar based on different workflows Improved meeting tracking: Organizers have more controls in viewing meeting responses, such as the ability to sort and download them. Typically useful when there is a large audience Meeting recap: The Outlook Calendar surfaces a meeting recap with recordings, transcripts, and shared files Filtered views: Allows you to declutter your Calendar so that it's easier to scan and schedule Change a recurring event: Users can modify future events of a series of meetings while preserving the configuration of previous ones Rename your email account: This labeling makes it easier to identify multiple accounts in Outlook Modern themes: Exactly what the name says, plus Dark Mode Keyboard shortcuts: This facilitates flexible user behavior as customers can choose between Outlook for Windows shortcuts, Outlook for the web, or turn them off completely There you have it. It's a decent list, but it remains to be seen if it will move the needle in a meaningful way for users who are attached to Classic Outlook. Again, a lot of the aforementioned features are already available in Outlook Classic, but for some, native functionality is not present, and people typically resort to workarounds. Microsoft will be hoping that it's primarily those capabilities that get people to finally switch.
