Hi everyone, I hope you can help. I'm currently running Windows 7 with MBR disk and have 1 unallocated partition ready for a Mac installation. Could you help me about general step I need to do to install 10.6.3 without messing up my current configuration I'm using it for work so I can't reinstall Windows. I have a 16GB USB drive, a retail image of 10.6.3. What kext should I use and where I can download it. I've read your post on #1 before but now it's replace with something else. My laptop is K40IN with T4200 CPU and 3GB of RAM. Hope someone can help.
