Apple sold PowerPC Macs within the last 2-3 years.

I've purchased more Macs than probably the demi-gods here have.

The list... LCIII, Quadra 605, Performa 6500, Powermac 6100, Powermac 8600, Powermac 8500, Powermac 9500, Powermac 9600, Powermac 7500, Powermac G4 sawtooth, 2 Powermac G4 Digital Audios, Powermac G4 Quicksilver, Powermac G4 MDD, and several Powermac G5s, along with 1 Intel Mac.
I'm sure I've forgotten a few along the way too. LOL

You?

Btw, Its not like I'm asking Apple to support 10 yr old machines, just ones 2-4 years old.

Apple previously supported Macs with operating system upgrades for 6-7 years!
And some of Snow Leopard's new features aren't even supported on many INTEL Macs!

So, you were buying a new Power Mac (not Powermac) every few models. What happened? Using the trends here, you should have several Mac Pro models by now. A really dedicated Mac fan.

I hear you though. But nobody twisted your arm into buying lots of PPC-based Mac models. I do not remember Steve Jobs promising to support your purchases for any length of time to coerce you into buying them.
 
If the leaked seed notes are any indication of what machines are "capable" of running the 64-bit kernel, there will be a new level of craziness around here.

There are no Mac mini or MacBook models on this list.

For the iMac and MacBook Pro, the models before 2008 are not listed.

I'm not going to touch the Mac Pro issues with a twenty foot pole.

On the 10A432 notes it only states 'capable' versus 'default' with the XServe range, so I am wondering whether Apple decided to stick with 32bit kernel across the range for all computers and only enabled it on their server.
 
Well I installed it. I figured it would be doing a fresh installation, but it actually went right overtop of Leopard. Went off without a hitch, though. Upon the first restart, it warned me that Rosetta would need to be installed for something that had to do with Nike+. Decided not to go against it.

Anyway, is there any reason I should go back and do a totally fresh installation of the OS? Are there any actual benefits? Or is that more of a mental thing for most people?
 
how should i install the new snow leopard seed?

i have a 1TB hdd with 2 partitions 500gb each. one is a TM partition other is for video files...can i create a new partition via disk utility and mount the SL there and boot from that? then i can restore it via the other time machine partition?

and once finished i can delete the SL install partition and all will be back to normal?
 
And why couldn't apple have given us 66 bits?

That would be 64 bits with a 'shave and a haircut' thrown in for free. A definite goodwill gesture to those of us still running Panther on our Enigma machines.
 
So not the GM

I work for Apple in London & i can confirm that build 10a432 is not the Golden Master it has just been given to select devs to test a few expert issues. 10A433 is on it's way (for server at least) and with uncomplete features like no prefs for quicktime and no default 64-bit for capable machines (i mean that not even the extensions are 64-bit by default). The installation has been polished and is being tested by the chosen devs. As i have heard there will be 1 or 2 more builds before it gets to golden master. There is still a bit of testing going on with the new bootcamp drivers but other than that it's basically there. i hope this corrects a few things, i'm not sure how pretty much the entire internet has got this wrong but none the less mistakes happen. :apple:

Yes mate that will work.
 
This should help

So how would one go about making 64-bit the default??

The 64-bit kernel can be tested on the following configurations:

Machine
Model name
K64 status



Early 2008 Mac Pro

MacPro3,1
Capable

Early 2008 Xserve

Xserve2,1
Default

MacBook Pro 15/17

MacBookPro4,1
Capable

iMac

iMac8,1
Capable

UniBody MacBook Pro 15

MacBookPro5,1
Capable

UniBody MacBook Pro 17

MacBookPro5,2
Capable

Mac Pro

MacPro4,1
Capable

iMac

iMac9,1
Capable

Early 2009 Xserve

Xserve3,1
Default

Using this seed*and one of the K64-capable machines listed above, simply boot the Mac with the '6' and '4' keys held down to use the 64-bit kernel. Observe that*uname -v*reports*RELEASE_X86_64. *Machines listed as "Default" and all Server installs will run K64 automatically when loaded with*10A402.

You can also set*arch=x86_64*in your*boot-args*NVRAM variable, using*nvram(8). When you're done, you can remove the boot-arg, or if you can no longer boot into an OS to unset it, hold command-option-P-R to zap NVRAM.

If you just want one partition to boot x86_64, edit the file /Library/Preferences/SystemConfiguration/com.apple.Boot.plist and add*arch=x86_64*to the kernel flags.

If some functionality is not working and you must revert to using the 32-bit kernel, you can either reboot with the '3' and '2' keys held down or set*arch=i386*in your boot-args.

Thanks for letting us know. Do you also know something about an early release? as John Gruber mentioned on his blog it could be available as early as August 28th.
 
Buzz!!

In a 64-bit Operating system, the memory technologies used can dramatically increase the addressable memory.

Ok on the addressable memory bit, individual applications can use more than 4GiB of RAM (even with 32-bit, the system can have more than 4 GiB, but an application is limited).

This has a performance benefit. With a 32-bit kernel, the kernel runs in its own max 4 GiB "container", and applications each have their own "container". When an application needs to talk to the kernel, the CPU has to switch between containers and this takes time. It can be a noticeable hit if apps frequently need the kernel (for example, to do IO).

With 64-bit kernel, an application "container" is huge, and the kernel "container" can appear (be "aliased") into a protected part of the application "container". Since the kernel and app are in the same "container", there's no "container switch" overhead.


It can also process strings 64-bits long instead of 32-bits long per cycle.

Not really, x86 32-bit can already deal with 64-bit data ("double" floating point) and 128-bit data (SSE registers).

The only new thing is that 64-bit integer operations can be issued in one cycle. 32-bit CPUs can do 64-bit integer operations, but it takes slightly longer due to the need to use two instructions.


(There may be more but I dont care)

One big "more" is that x64 has twice as many registers (very, very fast memory) as x86, so the compiler can optimize a program so that it doesn't need to use slower cache/main memory as much.

Who is John Gruber when he's not at home?

I'm more inclined to believe that the date, 28 August are when Apple will take orders and around that time will be when it'll go gold. I can't see Apple at this stage, still labelling 10A432 as a pre-release, no official statement to developers that it is GM, and more importantly, the isolation of a huge number of customers through limiting 64bit default to only their server range - it doesn't make any sense.

I'd say that Apple is waiting to get all their ducks in a row before releasing it; when Snow Leopard is released, all the vendors have either 64bit extensions available, updates for their applications or ready to announce native versions of their applications for Snow Leopard.

i have a 2009 mac mini and im pretty damn positive that it is fully SL 64-bit capable..kernel and all. It also has the 9400m nvidia graphics so it will do GCD as well...
i read on apples own site that the mini is fully compatible with 64 bit.
not sure why it isnt on the list there

Not saying what he hasn't heard is true or false but I don't think it is accurate. I do believe this is the gold master. There simply isn't enough time to go through another build, test that build, then go gold, press discs, package, ship to stores/users in a little more than a month. I don't believe Amazon would be allowed to take pre-orders unless a date was firm.

Now, this could be out there for devs to test and expect an update on the day of release. That would make more sense.
 
What's it matter if it's GM or not? If it works well, it works, right?

If another version comes out, can't you just install it on top of this one or just software update it? I'm not seeing the big deal.

once again, the 2009 mini should be on that list

I don't think the driver is final yet from Intel. At least under RC.

The RC driver from Intel definitely has "pre-release WDDM 1.1" in its ID string.

BTW, I've never had a BSOD from the driver. Just random pixel noise that is fixed by refreshing or minimizing/restoring the window in question.
