    I have a 27' Thunderbolt display connected to a 12' Macbook Pro (Late 2011). This display was working perfectly before I downloaded El Capitan and now the display goes black after a few minutes of use. Does anyone know why this is happening? I have read threads about this happening a lot with orders OS's but there isn't and fixes.

    Thanks

    I got my second screen to turn on again by changing screen savers. I'm seeing a problem with the second screen not wanting to turn on after Energy Saver turns off the screens.

    It seems only to happen with the Thunderbolt display. I have my laptop connected to my TV right now with no issues. I should've pointed out that the display goes black and turns back on. Does it every few minutes.

    Oddly enough, it may be the cable between the display and your mac. I had a similar issue after a point release in Yosemite, so I figured it was a software issue. I eventually read somewhere that the integrated thunderbolt/magsafe cable can be problematic, and to try a different thunderbolt cable.

    No issues since I've done that.

    YMMV, but worth a shot.

    Did you ever find a fix for this? Mine is weird: ever since "upgrading" to el capitan my thunderbolt display is just . . . temperamental. It'll work in the mornings, but not in the afternoons. Weird. Frustrating.

    Try this.

    Unplug the power for 10 second to your display then turn it back on.

    Then go to System Preferences, Energy Saver, choose the “Turn Display off after:” to “Never”.

    It is not the power problem or the cable problem of the firmware issue!!!

    Good Luck
