Title says it. Gigabyte P55A-UD3 mobo, i5-760 2.8Ghz, 4GB Kingston DDR3-1333Mhz,
Nvidia 8400GS,
WDC WD3200AVJS-63B6A0 partitioned GPT, 60G Mint Linux, 200G Users, 60G MacOS 10.6.8,
I've been using a naughty bootloader, with dsts, intending to move to MyHack.

Snow Leopard went in fine first go, has run fine for years (?). I chucked Ubuntu off the *nix volume because I got tired of it breaking drivers at upgrades. I agreed with those who said Lion was Apple's Vista. Now I would like to try 10.8 on a separate volume, not a direct upgrade yet. But the Appstore tells me,

We could not complete your purchase
We could not complete your purchase. OS X
Mountain Lion is not compatible with this computer.

System profiler tells me I have a MacPro 3,1 I used Champlist to assign plausible bootrom and s/nr values, extract attached. I read somewhere that amongst the ML install requirement is a need for S/L/E/AppleSMC.kext version at least 4. My "real" version is 3.1.0d5, but I do have /Extra/Extensions/FakeSMC.kext v.4.2.0. Now looking too deep I get confused, see the SystemProfiler extract which says SMC Version(system): 1.25f4. Alrighty, do ioreg -l -w0 |grep SMC and the result is attached.

The AppStore appears to d/l and run the installer Preflight check before letting you buy. Conveniently it leaves a copy at
/Users/~/Library/Application Support/AppStore/<9figure-index>/preflight.pfpkg
The "Distribution" xml script extracted is also attached here, zipped.
Have I fallen off the edge of the upgrade cycle? Is there something simple stupid I've missed?

You cannot run the native installer to upgrade your mac. I have the same mobo and almost identical hardware.

What you need to do is buy the ML installer from app store then use a 3rd party tool to convert it to a USB drive installer or DVD based installer.

I use the USB tool, installed the update just fine and once I got past some reboot issues was able to install my kexts and DSDT. ML is running great, much better than SL ever ran on my system.

I'm not using Software Update. I open the AppStore.app and navigate to the Mountain Lion page. Then when I click on buy, it barfs. Looking thru their support pages it may be possible it doesn't like my 1Mbit/s link, Apple's servers can't manitain a connection for 8 hours?

Rather than spend hours trouble shooting a system that you plan to replace as soon as you succeed, can you get access to a real mac to buy and download it on, then copy the installer app to a usb and copy it to your computer and go from there? 1mb/s would be slow for LAN, but a 1mb/s internet connection would be fine, take you an hour to DL ML
