Mountain Lion supports the Mid 2007 17-inch MacBook Pro. Does anyone know why Mavericks drops this support and starts with the Late 2007? Wikipedia says they're both identified as MacBookPro3,1. The only differences appear to be an option for a 2.6GHz CPU and slightly faster/larger hard drive options.
Has anyone actually tried Mavericks on a Mid 2007 17-inch?
The earlier machine supported a max RAM of 3GB, the later machine 4GB.
This suggests that the Northbridge and memory controller changed.
Also different GPU (NVIDIA GeForce 8600M GT instead of the ATI Mobility Radeon X1600)
- It may be that Mavericks requires 4GB (though my guess is that that's not it; Apple was selling 2GB MBAs until recently).
- It may be that Apple just doesn't want the OS having to bother with the older chipset (more likely).
- It may be that the issue is the GPU. X1600 was not supposed to be supported as part of ML, and if it was that appears to be luck on your part. (most likely)

well my imac has intel core 2 due 64 bit processor and 2007 MacBooks have that as well, so why not? 2007 imac with ssd runs pretty much close to my 2012 mba. as long as i don't encode videos or do heavy stuff anyway. so finally apple being NON-apple trying to sell more iphones 5 just for airdrop capability.
Airdrop requires specific WiFi HW to work because it operates even without a base station present --- that's kinda the point, that it works anywhere.
Airdrop on Macs is exactly the same --- it doesn't work on all Macs, only newer ones which have the appropriate WiFi HW.

I have a 3,1 MacBook (late 2007) and I can see I have 64 bit EFI:
$ ioreg -l -p IODeviceTree | grep firmware-abi
| | "firmware-abi" = <"EFI64">
So... Am I missing something? I've never tried to boot it with 64 bits, though, but I think I can... I'm using Lion right now, and I hate it. Hate it. I'm going back to SL if I can't get Mavericks to work.
What do you think? Should I be able to run Mavericks despite apple's official "support"? I think Mavericks would run just as smoonth as SL on this machine...
That's has Intel GMA X3100 graphics.
The cleanup of Mountain Lion officially dropped machines without UEFI-64 and with older graphics cards. People have hacked ML to run on these machines.
This may or may not mean you could do the same with 10.9. However with each new rev Apple is going to be more aggressive in using HW features guaranteed by the HW specs, without testing for bad compatibility. They may well, for example, just naturally use throughout the UI some OpenGL features which are not supported. The GMA X3100 only supports up to OpenGL 2.0.

I question their definition of "support". Example: my late 2010 MBA is supported by Mountain Lion, but not one of the key new features: Air Play. Buried in the technical notes, it explains that it can not be supported on my machine due to the graphics processor. A 3rd party program (AirParrot) works just fine mirroring my desktop and audio to my aTV.
So while Mavericks may "support" my MBA, I'll be shocked if AirPlay materializes. How knows what other little features are to be left out?
For crying out loud. None of this is secret. AirPlay requires SandyBridge or later because it is using SB to encode the video.
No-one is claiming there aren't other ways to do it. But Apple isn't interested in wasting engineer time figuring out three ways to do the same thing. They choose one way, the way that makes sense going forward, and use the rest of the time for other purposes.
What are you complaining about? You have an alternative, and Apple has ALWAYS been this way --- it's not like this is anything new. You will be able to use large parts of the new stuff in 10.9 --- but you'd rather be unhappy about the 5% of new stuff that you can't use?
