I have already read the Apple Support documents to the TDM, but this doesn't adress my questions: 1. if i connect my Macbook Pro Retina to my iMac via Thunderbolt, will the iMac run under full power, or is there only the Display running? Might be a question for power consumption. 2. Bootcamp isn't working with TDM, but will Windows show up via Parallels in TDM? 3. for which reason do you use TDM, and not only run your iMac, because you have to run two computers at the same time?
