I just finished installing 10.6.7 on my nephew's 530. I used the info and guides from here and myhack. It took a few attempts as I've never used any Mac ever. So, installing a VM on my desktop first was interesting too.
My biggest issue was getting ahead of myself. I was allowing 10.6.8 to install. This would cause boot and touchpad issues. Then I read some forum posts.
All in all, not the worst experience I've ever had installing an OS. But, I guess installing an OS where it doesn't belong shouldn't be easy.
Thanks to everyone involved in making this possible.
