    I currently trying to connect iMac late 09 in target mode to a MacBook Pro 15" but I’m not getting it detected.

    My setup uses Thunderbolt-to-Thunderbolt however this Apple document says I can use only work with Mini DisplayPort-to-Mini DisplayPort. Are those cables really different? Or am I having other problem?

    Yes they are different. You will need a Mini DisplayPort to Mini DisplayPort cable.

    You must use a miniDP to miniDP cable and not a Thunderbolt to Thunderbolt, it's different.

    With a 2009 or 2010 iMac, you must use DP cable.
    With 2011 (and +) iMac, it's Thunderbolt.

    You can use DP classic cable with mini DP adapter, it works too.
