Mac OS X Carbon will not be 64bit in Leopard. "At last year's keynote, Apple had claimed that both Carbon and Cocoa would be 64-bit, adding to the 64-bit fundamentals that Tiger had laid. However, according to the latest on Apple's website, Leopard's 64-bit frameworks will include the POSIX and math libraries found in Tiger, Cocoa, Quartz, OpenGL, and X11 GUI framework. In addition, Apple confirms that Carbon will not be 64-bit on the Carbon Developer mailing list." In addition, the readme file included with Leopard's developer preview says G3 support will be dropped from Leopard.

How is not having ZFS by default dropping features? AFAIK Apple simply never mentionned anything publicly about ZFS. All I heard about ZFS on Leopard was from external sources.

Also really... running a G3 on Tiger is already a pain. I don't want to know what it's like with Leopard.

If you want to use your old machine for a server then there's always a good linux distribution suited for it.

Not true.

1.) There are 900MHz G3 iBooks out there.
2.) Tiger on a G3 is as fast as Panther on a G3 which is MUCH faster than 10.2 on a G3, which was the preinstalled OS on those iBooks. So if you claim that running Tiger on these machines is a pain, you'll have to argue that using these machines was an even bigger pain when they were brand-new.

Apple has only so much it can support.
Keeping older hardware supported
1. Means you can't effectively use the features of the newer hardware
2. You strain your development/support teams beyond what is possible.

I feel Tiger slow on my iBook G4 800... much slower than XP on a 800 MHz Pentium III. I don't believe they can make Leopard faster than Tiger in any appreciable way, so I'm not going to upgrade this machine.

Back in the days, there were a lot of people who wanted to switch back to OS9 exactly for this reason!

If I could mod you straight up to 5, I would. Heck, if I could mod you way beyond 5, I would.

You nailed it.

OTOH, Thom (or Jeremy, I dunno, but it's still Thom's job to dig deeper into the story!) *so* cherry-picked the email in that thread that he found news-worthy.

Check these out (both by the very same Eric Schlegel):

There's hardly a lack of care for the current developer situation. Specially when there are sessions *dedicated* to the subject on WWDC itself!

Mass hysteria seems to abound, though.

Anyway, I still pretty much doubt that Leopard can't be shoehorned into quite a number of G3's at all.

My Performa 6360, running 9.2.2, can attest this. Manual ResEdit intervention was necessary, but it works like a charm.

Same as my iMac Rev D, running the very latest release of Tiger. XPostFacto to the rescue.

But we'll know the *real deal* in due time.

(Sidenote: who in a right mindset would run Vista, or even XP, on a processor that tops at 900MHz (and those are few and far between), especially processors lacking any kind of SIMD extensions? Not to mention how most G3 motherboards can't support more than 640MB of RAM. Really, wake up and smell the coffee. And those rare, fastest-ever-produced G3s were discontinued in 2003. 4 years already!

Now, how about unreasonable expectations that Apple itself will continue supporting machines after they EOLd? Try Ubuntu PPC for a change! Or Xubuntu if you machine is lacking RAM and a larger hard disk.)

Anyway, my souped-up iMac 333 won't cry missing out on Leopard until I'm pretty sure XPostFacto won't do its magic; and it's not like it feels any zippy on Tiger already.

And it will take a couple years for Leopard-exclusive apps to become the norm. Until then, Apple will continue releasing security updates for Tiger, as it currently does for Panther.

So really, what's the big deal? You can't run the glitz already. A hardware failure might be on the verge of happening (specially the HDs, those tend to fail quite frequently!).

What about saving some money or getting yourself an el-cheapo G4 on eBay?

XP Pro runs quite well on my Dell Dimension 4100 (933Mhz PIII, 512MB RAM).

XP came out when 600Mhz PIII's were the norm, and it ran decently once SP1 came out.

You do realise however that Pentium IIIs have SSE extensions, in addition to MMX, right? And how much RAM do these motherboards support, again?

Re-read my post, please.
