Hi all, I have a MacBook, Late 2006, White, 2GB RAM, running OS X Lion. I was wondering whether I could use this as a second monitor for my iMac 27" Late 2012? If so, how would I go about the configuration and setup? I would also need it to function as an independent notebook as well, if I were to disconnect it (wired or wirelessly) and use it separately. Thanks in advance.
