Hi guys I've built a system for a friend of mine who has also had enough of windows so i'm trying to install on Tonymacs recommended build 1: CPU: Intel Core i3-2100 Motherboard: Gigabyte GA-H67M-D2-B3 Graphics: AMD Radeon HD 6670 changed for NVIDA GEFORCE 8400GS RAM: Corsair XMS3 4 GB 1333mhz DDR3 (4GB) Case: Cooler Master Elite 341 Power Supply: Corsair CX430 Optical Drive: Sony Optiarc Hard Drive: Seagate 1 TB 7200RPM Installation DVD: Mac OS X Snow Leopard 10.6.3 & DSDT downloaded from database I installed 10.6.3 with no hitches and updated to 10.6.7 with the intent of upgrading to Lion (some of you may say I must upgrade to 10.6.8 for lion but you don't have to, I have installed on my own laptop twice with this method). When I open lion it says I must have a dual core, i3, i7 ect to install so when I checked about my mac it shows up as "unknown" instead of i3. I thought maybe this would be corrected by running multibeast, selecting user dsdt and rebooting. It won't boot from disk only iboot, it still shows as unknown processor and when I checked the /extra folder my dsdt is not there. I ran multibeast and it would not copy it across so I thought i'd manualy copy it across and that would sort it. It's present but still will not boot, doesn't recognise the processor and when I just tried to update to 10.6.8 to make 100% certain, when it got to just over 3/4 it kernel panicked. Can anyone help me on this please??
