    So, software update today addressing the core shutdown issue.

    I turned off Coolbook (uncheck "Coolbook Active"), rebooted, installed the update, rebooted, turned Coolbook back on and rebooted. By now, my machine was pretty warm, so I put it to sleep for a couple minutes.

    Then I ran 10 minutes of Youtube videos. My max temp was 66 degrees. My fans stayed low for the first couple of videos, then slowly crept up to 4500 RPM over the course of the third video. I think they would eventually reach max fans, but it looked like another 10 minutes or so to get there.

    Compared to before, the fans definitely came up much more slowly, so that's good. Otherwise, everything seemed to run normally for me.

    Environmentally, the ambient temperature in the room is about 75 and I have the machine on my lap (so some of the vents are blocked).

    In my opinion, the update looks good. Despite the warning in the update, Coolbook still works fine and still provides a superior heat management technique (by generating less heat in the first place). I recommend using both!

    Edit: I can't report directly if the update fixes the core shutdown problem since my machine has never experienced them.

    Coolbook works. Apple says its not recommended since they use a different style of throttling in which if Coolbook was enabled would override the Apple's settings.
