I have been hearing that 10.7 will only be supported on Mac Pro 2009 models and up.

Would be interesting if that is the case, probably has to do with the 64bit EFI
 
I'd expect at least a Core2Duo and up support, 2GB Memory ...

For some of the newest features, we may see some CPU and/or GPU limits.

Typically this has been filters and such, but we may seem them push a bit outside that box.

Basically the 64-bits will be 64-bit capable CPUs, likely not EFI, like it is now. We will just see them ejecting some Intel CPUs with this next batch and limiting the GPUs.
 
And your source is? Only 2006-2007 Mac Pro has 32-bit EFI so IF 10.7 has only 64-bit kernel, then it should work on 2008 Mac Pro as well.

Mac Pro 2009 and up would mean that pretty much all non iX Macs wouldn't support it and that sounds ridiculous because Apple still sells computers with C2Ds.

Probably not any more when 10.7 will be finally available (certainly not before the end of 2011).

True but it would still be ridiculous. Less than a year-old computer that cost over 1000$ but it does not support the latest OS :rolleyes:

Can't see it happening
 
I don't think they would leave the C2D owners out of the upgrade. Now, I can see certain features not being enabled for performance reasons.
 
Not a chance.

10.7 will support everything C2D and up, I put money on it.

Lets not forget the current MBA and 13" MBP and MB are all C2D.

Simples.

PS: It doesn't matter the EFI is 32-bit, Apple can change that if required...
 
Better not be....

If it does turn out to be true, then Mr. Jobs will leave work one day only to find my 2008 Mac Pro penetrating the windshield of his car.......

You've got to love at the amount of bollox already being posted about an OS, we don't even know the name of, let alone any specific features.
 
Has Apple ever actually placed processor speed restrictions in the system requirements? I know they put requirements on RAM and processor architecture, but I've never heard of them saying "that processor won't cut it."

Apple wouldn't do that because they want people to buy new Macs.

Mac OS X v10.5 Leopard requires:

A Mac computer with an Intel, PowerPC G5, or Power PC G4 (867 MHz or faster) processor

Whatever.

I guarantee you 10.7 will *not* require 64-bit EFI.

The general public would not understand why W7 x64 could run but 10.7 can't.

I agree with that. Just noted that I doubt that Apple would update the EFI to 64-bit on four-year-old machine.

Besides, 64-bit kernel is quite useless for most people but it would require some drivers to be rewritten (I think) so I can't see Apple doing that. Also, it would sound stupid if Apple again advertised their new OS as 64-bit... I guess we'll know in few hours :p

Where because apple isn't talking, in fact very little information has been leaked, including the name of 10.7. People have "Assumed" the name is lion but its just that an assumption. Likewise the requirements for 10.7 is just pure speculation.

Apple has generally done a great job at supporting legacy hardware, look at how long it took them to drop PPC frameworks and go straight to intel.

I don't what the minimum requirements for 10.7 will be, but apple knows and that means we may hear (and we may not) it later today.

It is not about "it should work" on the hardware. 10.6 could have worked on the about 3 year old (when 10.6 went into developer release) G5's too. It is about whether Apple puts the machine into the QA regression test set for the release and subsequent updates. If 10.7 "betas" are not tested on 2008 models then it will not be released for it. ( it might work with some hacking, but it won't be supported).

It may boil down to numbers. There may be not enough 2008 models to make it worth the extra expense. Additionally, the release date for 10.7 may move the 2008 models on to the "too old" pile.

Apple kills off support for older machines. 10.7 will probably release around Q4 2011 or Q1 2012. At the latter point, a 2008 machine is minimally 4 years old. Is that machine even being supported by Apple anymore? Even with Applecare you are out of the window. If on a 3 year depreciation schedule, then at 4 years you are past zero. On a 5 year schedule, you only have a year left.. ( should be far more worried about migrating to new box than installing a brand-spanking-new OS. Need a stable current system more than a new one. ). 2007 is definitely out of the range Apple will support just on age not hardware capabilities. The more the 10.7 release slides into 2012, the 2008 machines will be just as "too old". (the MP release date in 2008 was Jan 2008. That means 10.7 need only slide one month into 2008 before all the 2008 models are "too old". Somewhat likely the "stable enough for production" version 10.7.2 won't even be out by then even if did release in then. Definitely would be "too old" for all the subsequent dot releases. You can't just look at the release date. Apple isn't going to stop supporting a model with the 'dot' updates. Once on board at the beginning supported till releases 10.8. that is another two years. ).

You can see where Apple is moving to a model where users get one, maybe two Mac OS X upgrades before they drop support. That's because Mac OS X is on a 4-5 cycle for those two updates if measure "first release" (on first) to "stable release update" (on second). Apple openly said a couple years ago they were going to slow down the pace of Mac OS X updates to a somewhat slower pace. 2+ years is likely what they are going to settle into.


Mac Pro 2009 and up would mean that pretty much all non iX Macs wouldn't support it and that sounds ridiculous because Apple still sells computers with C2Ds.

No, they could just cut Mac Pro 2008s and leave the a large body of C2D in. All they have to do is cut the opaque misdirection pointing at CPUs when this is really about cutting off old hardware system platforms. Apple is trying to use CPUs to date the platform (hence the xxxMHz sometimes. ) which is imprecise.


The 2008's would get security updates via 10.6. They will be in "extended life support". However, at end of 10.7's period as lead release, it would be around 2013-14 and the machines are 5-6 years old. That's a long time in "computer years". Users are free to keep using machines that old, but the primary purpose should be to look in the rear-view mirror running "2011 and previous" era software. 10.6 will run the vast majority of those just fine.

And what would be the point to do that since 2008 Mac Pro is faster than any Core 2 Duo that Apple has used? Yes, Apple could drop support if they wanted but I can't see why would they do that for 2008 Mac Pros.

Maybe you should try to summarize your point a little. You wrote a wall of text but at least I don't understand its meaning.
 
Apple did not update Mac Pro EFI to support new GPU's.

They will not update EFI to support new OS either.

2010 Mac Pro already started booting default to 64bit.


My bet is that 10.7 will req 64bit EFI and that will not let you install it on a 2006, 2007 Mac Pro.

You can shout "that will never happen!!! apple is teh good guys!!!" all you want, Apple doesnt give a **** about stuff they are no longer selling and this has proven in the past.


I doubt we will know any more after this Keynote, it's unlikely Steve would say "Oh and hey! We are dropping support for old machines!". This keynote is about showing of features, not issues.

Well that's a load of BS. The whole point of 10.6 was to remove PPC binary and make the OS more efficient for the future on Intel machines.

Apples support for older machines has generally lasted 5 or 7 years. A G4 that originally came with 9.0.1 was supported all the way through until 10.4. That was a lifespan of 7 years.

Your 'magical' theory makes no sense on any level. Hellhammer is spot on. What is the point of your long post.

You think Apple will drop support for machines because of it's age, regardless of the fact it is faster and more powerful then 95% of Macs sold?

Well you don't know anything. 2008 Mac Pro comes with 64bit EFI. Do your research first.
