MacBook1,1 processor upgrade.

While this is technically possible, yours being a Core Duo machine doing that upgrade would require the replacement of the entire logic board.

Better and more economical to upgrade to a newer MacBook like the 2009 and 2010 Unibodies. These are upgradeable beyond Snow Leopard and can be had for $200 - $310 depending on the internals, condition etc. Plus they look nice.

Other choices would be the later MBPros, say 2009 and beyond.

I am afraid as Spudnuty said it will require a new motherboard to get all of the correct chips for the new processer. Since new motherboards never fit into old cases, you are either stuck with what you have or you upgrade to a new MacBook. But you are not going to be able to have your cake and eat also.

"if I could fit a newer motherboard into my MacBook, would it be unstable"

No it would be stable.

"would it still recognize the Model ID (MacBook1,1) and such?"

No, it's like doing a brain transplant. The body would be the same ( Uhh, actually only 15% the same on later examination!) but the brain would know it was different. See because you changed the brain (CPU) it knows it's different (Core 2 Duo capable of running 64 bits) vrs the old brain (Core Duo limited to 32 bit).

So in order to change the logic board from the early Core Duo to the Late 2006 Core 2 Duo the following items would have to be changed (Not a complete list.)

Battery, RAM, RAM door, Lower case, logic board ( of course), heat sink, DC in board, fan, top case, display,.....Uh it would have been a shorter list to list what was the same. You could keep the back of the display case with the Apple logo on it but just about 85% of the rest of the computer would be new parts.

See, that was a big jump to go from the Core Duo to the Core 2 Duo and that happened in the course of 6 months or so.

So I totally understand your attachment to your MacBook. I picked up an old Bondi Blue iMac that was going for donation to a kindergarden. The first iMac ever one made and this older guy had had it for 7 years. He asked to have a few moments with his iMac and he sat with his arm around it for 5 minutes while I waited.

When those iMacs went into the kindergarden the kids kissed and hugged them. You don't see that kind of love with Dell!

I still have my MacIntosh SE 30 and my IIfx sitting in my closet. I've hauled them from Chicago to Idaho to Portland over the last 25 years. So yes I understand.

Especially with the early iMacs. There were mods back then replacing the CRT with and LCD and putting an Intel Mini in place of the lower case.

I I would like to update past Mac OS X 10.6.8 Snow Leopard but a 64-bit processor is required. is there any way to do this?

No, a Mackbook 1.1 will not be able to operate any newer OSX than Snow Leopard. All of your thoughts regarding hardware changes on this unit are for naught. A newer MBP will be required to run Lion or any newer OSX.

Ciao.

A Macbook 1.1 will accept up to 2 GB RAM with the following specifications: 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM. The best sources for Mac compatible RAM are OWC and Crucial.

The storage can be increased by installing a larger SATA HDD or SSD. Up to 2 TB storage is the current limit but that may change.

in practice you can not fit a newer motherboard, so the question is moot.

What Spudnutty says is basically right. The 2006 and early 2009 macbook are physical the same.The memory is different. The plugs in the logic board are the same. and the ram door is the same. Many of the parts interchange. The dc in is different, though they physically fit as is the battery cable. I have had both apart. What I do not remember is,while the logic boards are the same size and shape, the screw mounts may or may not be in the same place. The keyboard and top cover assembly are the same and can be interchanged. As also the battery. It's a lot of work. I bought a 2010 macbook that works good and only needed a bottom cover for $150.00. So it would be easier to go that way then to try and change the logic board on your 2006.

What part of no don't you understand?

If and only If you could do this,you would spend enough money that you could have bought a newer one. There are also 50 or more screws that have to go back in the right place also. Make a mistake and you brick the whole thing.

Purchase one and see if it fits. Please report your results to us so that we also can profit from your experience.
