Mac OS X Lion *does* run on Core Duos/Core Solos.

Typical of Apple to kill off support for perfectly capable systems.

This is Apple. This is what Apple does. Everyone knows this by now.

Have any older systems?

Ever check the Mac OS X 10.3 System Requirements? (http://support.apple.com/kb/HT2176)

Requirement for G3 systems: "built-in USB ports"
I had some nice G3 systems with maxed out RAM. Even though I could easily add a USB card to the system, Mac OS X 10.3 refused to install because the system didn't have *onboard* USB ports.

Ever look at the Mac OS X 10.4 System Requirements? (http://support.apple.com/kb/ht1514)

"Built-in FireWire".
That's right. Turbo-charged systems with a ton of RAM, more than capable of running the OS would be blocked from upgrading because they didn't have *onboard* FireWire.

XPostFacto (http://en.wikipedia.org/wiki/XPostFacto) is what I used to install Mac OS X on systems that Apple seemed to remove support for (with no good reason).

Apple dropping support for 32-bit Intel isn't a big thing. There are probably a LOT more people with PowerPC systems still angry over Apple dropping support for that. Personally, I work with tens of thousands of dollars of Apple server hardware, all stuck at 10.5 because they came with the most expensive, best G5 chips in them.

There isn't any solder holding them on. The earlier ones have a P socket and can take up to a Core 2 Duo, just like the early Intell Mac Mini's.

Dude, you don't know what your talking about. First off, it's "Intel". Second, the only Intel Macs with socketed processors were the Intel Minis, Xserve and Mac Pro. Everything else is soldered.

I most certainly do know what I'm talking about. All Intell iMac's have socketed CPUs. Futhermore, the 2009 and later Mini's are soldered to the board and are not upgradable. Please research before spouting misinformation next time. Here are some threads/links (with pics):

Intell with two L's? Its a reference to my user name.

It should be the twist of a flat head screw to unlock the processor from the socket. That is after the teardown before you reach that point.

Okay, fine. The iMac is socketed. But the MacBook and MacBook Pro aren't. You have been implying they are.

The Mac mini was socketed up until the current version. If we are talking about upgrading a Core Duo machine to Core 2 Duo, it is going to be a Mac mini or iMac.

You are looking at replacing the entire logic board for a notebook. Where is the implication again?

Oh, you edited your post. I believe it originally said

You later added the "i".

That "i" was there from the beginning. You are trying you hardest to win this argument by falsifying things. What about the edit at 4:22AM you might ask? That's my signature. Look around its on all my posts.
 
I guess I might have made a mistake.

I'm not even about this anymore. I'm wondering why I even care as none of this pertains to me. What I originally opened up my browser for was too look for a new GPU for a hackintosh, not to be on MR.

Whatevs
 
...indeed this is less lame than the likes of "built in USB and built in Firewire", but unnecessary nonetheless.
 
I just read the first and last pages of the thread, but can the Lion GM be installed on Core Duo machines? I know Apple made it tougher this time around than with Leopard... Leopard had an 867 MHz G4 requirement, and all I had to do to get it on an 800 MHz eMac was install on an external drive and CarbonCopyCloner the drive over to the eMac. None of this .plist stuff... oh well...

No, it will refuse to boot. The minimum is a Core 2 Duo.
 
Hello,
I'm just curious to known if we have all exactly the same DMG file

(in the past, I see that there is a "signature" on each DMG of a package)

can you compare the crc32, md5 or sha1
(you can use crc32 command from terminal)


My info for InstallESD.dmg from Lion GM:

size:
3743009943

crc32 :
e2223190

md5:
b5d3753c62bfb69866e94dca9336a44a

sha1:
e05c4c7c43b210d0b8fc265c609f4dd70617ff86
 
It's not deemed to be a user-serviceable part, and as a consequence you're voiding your warranty by replacing it. Sucks, but that's how these things work.

WTF does the warranty have to do with anything? He wasn't asking for Apple to fix his machine. :rolleyes:
 
So, I just bought a 1.86ghz Intel core duo iMac. If I upgrade the ram to 2gb and the cpu to a t7600 Intel processor will I be able to run Lion without a problem? or will I need to do something special? I am talking about the final release not the early betas.

And is it at all possible to run the Golden master on my Current specs on the iMac of 1.86ghz Intel core duo, 1.5gb of ram, and 128mb radeon x1600?

Thanks
