    Does Mini DisplayPort adapter work in Thunderbolt Port?
    I understand that the Thunderbolt is backwards compatible and therefore works in the older versions of the MacBook that have the Mini DisplayPort.

    I read somewhere that you cannot use a Mini DisplayPort adapter in the Thunderbolt port, is this true? And if it is true - how have people been transferring video/audio to the newest MacBook Pro model the past few months (with the Thunderbolt cable only just being released?)

    Thanks

    Patently false.

    Specs:
    15" MBP '06 2.33 C2D 4GB 10.7; 13" MBA '11 1.8 i7 4GB 10.10; 21" iMac '13 2.9 i5 8GB 10.10; 5s & 5c
    The Thunderbolt port on a Mac is backwards compatible with mdp.

    You are not going to connect a device that requires Thunderbolt to an older mdp and expect it to get Thunderbolt speeds. As to whether it will work at all - probably - but, I have not checked that out and don't really care as I'm not going to spend $50 for the TB cable on a Mac that does not have TB when I can buy mdp cables all day long at less than $10.

    The older mdp has not somehow become magically TB capable.
    Even though Apple likes to throw that term around.

    OK thanks but the main thing to confirm is that MDP do work in the Thunderbolt port?

    Well sort of
    I went through the trouble to buy both cables, including a new macbook air with thunderbolt to get the right combinations of options. All the results are posted here: Thunderbold and MiniDisplay Mac Compatibility 101 Mike95 Blog Hopefully this saves lots of people the compatibility griefs and alleviates the doubts of others. Thanks

    2nd that - nice job.

    Just answered the question everyone has about the new Thunderbolt Cinema Displays.
    They do not work with a MDP out. Must have a video card that outputs via Thunderbolt and a Thunderbolt cable.
