Try rolling back your ACPIPlatform.kext to the one from 10.8

Funny thing, I was trying it to make a hackintosh for a startup I am working at and they just got macbook pro

But, I think I will still give the last two replies a shot.

Will confirm when done successfully/unsuccessfully.

Thanks for the reply. This actually looks like a flow I have not tried. Will give this a try.

Btw, I think I will be following the same Probook installer options as listed above. I hope it goes fine.

Will let you know once I try.

You might want to double check your Probook Installer v6 settings... Because you say you have a 4530s and you say you selected the 4730s DSDT. That won't work.
