Thanks Imkantus.

Well I trashed the extensions.mkext, rebooted the computer and I wrote it in Terminal: "sudo kextstat | grep -i nvdarwin"

Appeared this:

" 86 0 0x47bdf000 0x6000 0x5000 com.nvdarwin (1.2.5) <17 12> "


Whats the result? Was nvdarwin loaded sucessfuly?


Thanks.

One other question.

I have Leopard 10.5.5, and in order to sucessfuly install and run the xCode(iPhone app) I need Leopard 10.5.7. Can I upgrade to 10.5.7 without a new installation of Mac OSX? Or do I need to download other CD with Mac OSX and install it again?

Thanks
