Greetings all! I'm in the process of upgrading my early 2008 Macbook Pro to one of the new models. The new models have replaced the DVI output with a Thunderbolt connector. Since I have an older Apple Cinema display that connects by DVI, I'll need to buy a Thunderbolt to DVI adapter. However, I also use my computer to give presentations, which involves hooking it up to a VGA cable. I have been using Apple's DVI to VGA adapter for that purpose. So then, here's the question: would I be able to chain display adapters (Thunderbolt to DVI adapter, then linked to my old DVI to VGA adapter)? Or will I need to purchase a Thunderbolt to VGA adapter? Thank you for the advice!
