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

that is strange - I tried the Firewire kexts... I'll give it another go
As for Finder - perhaps we should just focus on finding an alternative?
Next week I'll do a clean install to see if I forgot another step. I'm very busy this week so I can't try anything. If you succeed, please tell us

ok so I got it booting - slowly working my way through frameworks to get DP1 Finder to run - painstaking! I thought maybe the DP2/DP3 Finders had 32bit code... Will try this tomorrow. I suspect the SysLogd problem may be our biggest hinderance mind.
Ultimately if the retail version is 64bit beyond the kernel this work may be moot - but I'd still like the options of a Snow Leopard/Lion DPx/Ubuntu Macbook
OK, so it looks like Apple have disallowed Core Duos because of a technical reason, and not just to force people to upgrade. Good.
Hi,
There are not significant performance differences between core duo and first core 2 duo macbooks. In fact they share the same chipset. I think it's a decision of apple to force developers to make x64 only apps.
Soon after I posted that I actually read something saying that the Finder is now 64-bit only, so that could be it.
Any summary for upgrade-to-core2duo users?
So if the Finder is indeed 64-bit only, I imagine that's not good for coreduo users.
However, what does this mean for those of us who upgraded the CPU on the motherboard from a CoreDuo to a Core2Duo? We now have a 64-bit capable machine, from the CPU standpoint - does it matter what's in the ROMs?

You'll still be limited by the logicboard's model ID not appearing in the list(s) of supported boards.
The 32-bit EFI is not an issue. The first Mac Pro has a 32-bit EFI and 64-bit Xeon CPUs that can run Lion without problems.
32-bit EFI is not a problem. So far (in DP4) 32-bit kernel is still there.
32-bit kernel will have to stay, since Apple have already announced the minimum requirements to run Lion. And there are some Mac's have made to the list with EFI-32 only, example is early 2007 Mac Pro with Xeon processor (64-bit) and EFI-32.
EDIT: Sorry I did not see Intell's reply above.
That's good. I must be behind on my reading. I read somewhere on this forum, that my first generation imac cor 2 duo couldn't run Lion, because of the 32 bit EFI.
I've also a MacMini1,1. I had removed the Core Duo and replaced by Core 2 Duo (and snow leopard run well 64 bits apps)
I'm surprised by your message.
I transfered DP4 dmg to an USB hard disk, I tried both modify or remove /System/Library/CoreServices/PlatformSupport.plist without success : after boot on the disk, installer say computer is not compatible
Ever since DP2 it was not possible to get Lion working on CD Minis with only the PlatformSupport.plist modification. It'll require something more along the lines of a modified boot.efi file to get it to work.
...and you'll need a replacement for the Finder which is a purely 64-bit app now. (and was before.)
So if you had, for example, a Core 2 Duo upgraded MacMini1,1 (which originally shipped with a Core Duo), what's the procedure for getting Lion running? Does the installation need to be done on a genuine Core 2 Duo machine and then moved, or can it be done in another way?
Currently, Lion will not boot on a MacMini1,1. Even with a C2D upgrade. It has to do with the Mini's logicboard ID not being in the list of supported boards. There are a few places this list exists. The harder/hardest of the places is currently the boot.eif file.
