Apple ThunderboltEarlier this month, I bought a new MacBook Pro, the one with the new thunderbolt port which is 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0. It also works with the Apple LED Cinema Display, which I have.

Or so they say.

For some reason, I and others with my configuration, are reporting in a Apple Help Forum that our displays flicker and go black every now and then for a second or two.

The flickering and blackouts happen initially a lot when you first plug in the display to the MacBook. Then over time, it slows down and towards the end of the day it either doesn’t happen or I do not notice it anymore. But when I notice it, it is annoying.

As I said, there are others with my configuration reporting the same issue at the Apple Help Forum.

Apple Display

They have an Apple Display connected to their new MacBooks over the new Thunderbolt port. If you have this issue also, submit it via the Apple Bug Report form, cause as of now, no fix is in the works.

I certainly hope it is a software fix…

Here is a video of me capturing the issue twice:

    I have the same problem. When I upgraded my 13 inch MB to a 15 inch MBP, from day one it never worked with my 24 inch led cinema display.

    Months later, same problem. I see they released one firmware update for Thunderbolt, but that did nothing to address this problem. My guess at this point is that its hardware related so they are choosing to ignore the problem.

    Just when I was convinced Apple makes the best stuff…I never had this problem with Dell. Never. So pissed off.

    I’m glad you were able to capture this. I’ve had this maybe 5-6 times as well since August 2011. What worse in my case, it happens with the Promise Thunderbolt Pegasus Raid as well. In that case, it means not only flicker to the connected display, but also a filesystem disconnect and (luckily not yet) potential data loss.
