Also note that there are third party ways of booting a Mac Pro 1,1 into EFI64, so this is hardly the end of the road.
 
Just a reminder that, at some point, my 2008 model will not receive updates.

I don't really have any limits on it right now except for no USB 3 support, which no Mac natively has anyway.

SSD makes booting fast. 14GB RAM means that RAM is not a limitation. Still faster than my 2010 MBP.
 

Dude, you said 64bit EFI, not the same thing as 64bit kernel, not by a longshot.

Eventually everything becomes obsolete, sure, however unless Apple makes some significant architecture changes to OS X, I can't see how a Mac Pro 3,1 won't be supported for a long time, and I am talking about a future version of OS X being blocked from installation. I mean I suppose they could do it with plist's if they wanted, but I mean from a hardware perspective. The Mac Pro 3,1 was the first Mac Pro to have 64bit EFI and as long as that is continued into the future, it should be supported.
 
I read the thread. Much of it is beyond my understanding, but in any case it seems to be about booting into a 64-bit kernel on the Mac Pro 1,1 (as the thread titles states). It does not provide any sort of solution for 64-bit EFI on Mac Pro 1,1 as you claim.

The 64 bit kernel is the part required for Mountain Lion.

Basically it's emulating 64 bit EFI to get the 64 bit kernel to boot.

Perhaps, but as far as I know, there is no way to boot a Mac Pro 1,1 or 2,1 into 64bit EFI, which was clearly what you stated. If I am wrong, please prove it so.

Uh, I just did. You load on an EFI program capable of extending EFI32 with EFI64 capabilities.

Which is what I just linked to.

EFI is extensible with an API. Anything missing you can add on yourself. It's not going to get you EFI64 on the board, but you can add back in the same functions. Like booting K64. Which is what you need for Mountain Lion and is why everyone is complaining to begin with.

This Mountain Lion thing is hardly the end of the world.
 
This article doesn't say anything at all specifically about the MP 1,1 so are you assuming my omission the 1,1 will be supported?

This article has a more detailed list of supported Mac's and clearly states that only the Mac Pro 2008 going forward will support Mountain Lion.

No I am not assuming anything, I just referenced it because it was contradicting what you were saying. I don't really care that much either way, its just a bummer that our machines became outdated over night; even though by some benchmarks they are faster than some newer machines.

Has anyone tried to install the Developer Preview on a 1,1?

More worried about iOS + OS X marriage made in hell and possible end of the creative world.

People with 1,1's have had the ability to upgrade to 4 major OS's. All with differing implementations of 64-bit ' ness. Just buy a new motherboard once in a while. Stop complaining, you more than got your money's worth. Most people update HW every 3-4 years is they want to stay with the latest and greatest OS. I can run whatever I want and choose to run 10.6. Because it is superior. Why always with the newest and it isn't even out yet and it is even more painfully iOS?
 
My 2,1 has a modded 5870 in it (though an Apple one would work), on Snow Leopard. I've been planning on getting an SSD for Lion.

The thing that gives me hope, is that using the Hackintosh communities bootloader, EFI32 machines like mine can be set to boot the 64-bit Kernel. At that point, my 2,1 should be fine. Of course, going that extra level might be a little ridiculous, and it was for Lion- there was no REAL need to do it except to get that 64-bit kernel.

Now that ML may block off EFI32 via a 64-bit kernel requirement, perhaps they'll be a better, more Mac-focused (as compared to Hackintosh) solution to streamline us into ML support.

Now I know how all those old machine owners felt in the days of XPostFacto.
 
Your Mac pro is slower than my Macbook Pro.

6 years in computer years is about double the average life expectancy. You had a good run, let it go.

Or live with Lion/Snow Leopard...

It's still heaps faster than the slowest supported iMacs, MBs and MBPs. Makes no sense. My 1,1 3.0GHz is faster than the latest base Mac Mini.

Six years is just an arbitrary number. It's like saying to a 101-year old that he's waaay over the 82-year average life expectancy. He had a good run but he's not getting support anymore regardless of his health or condition.

No, its not. Most extended warranties are 3 years. 6 years is DOUBLE that.

Find another hardware manufacturer that provides extended support for desktop computers in excess of 3 years and get back to me on that.

Dude, calm down. Machines newer than the 2006 Mac Pro were dropped with Lion.
 
re: Video

To be honest, I'd be *very* surprised if many 2006 Mac Pro owners still use one of those ATI X1900 cards?! Mine burnt up years ago, and I understand pretty much all the "revision A" versions of those had issues drawing lines through the display when you upgraded to any version of OS X newer than Tiger -- even if they were still functioning properly/as intended.

Even when people were able to exchange one of those under Apple extended warranties, I believe Apple sometimes substituted an nVidia 8800GT.

Those cards had a poor cooling design and the original heatsinks got all clogged up with dust, causing them to overheat and cook to death.



Buried in one of the ML discussion thread was a post that the desupport is driven by age and graphics as primary drivers. Included in the list of problematical graphics was the ATI Radeon X1900 , which shipped with the 2006 Mac pros. In part, this is because AMD has desupported the cards.

It is not simpily 64-bitness. There are iMacs with Core2 (supports 64-bits) that are disappearing too.

I'm calmed down, just disgruntled. I can afford to throw down 3-4 grand on a new one, it just seems silly when this machine is so easily capable still.

It does not have the ability to run 64-bit EFI as mentioned many times. 64-bit "capable" has been part of the processors since G5. 64-bit has never been fully implemented by default end to end until 10.8. There was always some sorts of 32-bit emulation. Apps can run 64-bit on a 32-bit kernel and visa versa. It is a continuation put in place since IBM G5's. Plenty Intel Mac's can't officially run 64-bite kernel in 10.6 or 10.7 which is no big deal as there is a 32-bit kernel still. It is now gone.
 
Switch to any flavor of Linux that has software you can use to keep on going. You would be surprised on what free and paid software that's available on Linux. One of the reasons I switched. Personally use ubuntu and enjoying it.
 
This is why i am glad i managed to get a '09 Mac Pro, It is sad to see that they are dropping so many Mac's from this update though!

*Luckily my '08 MacBook Pro can still run it! Another year still left for it!




For a 6 year old computer, the 1,1 Mac Pro has done VERY good job! After 6 years... it kinda is time to upgrade. You can still get a fair bit for a 1,1 on eBay though.
