HI, running OSX 10.58. Several times in the last few days, when I shut down via control option apple plus Eject it seems like a normal shutdown. Then there is a restart with no boot cycle, just a dark monitor and more fan noise than I've ever heard from my mac. It's a 2 gigahertz motorola dualie. I know what the noise level is if the processors both go to work on something, This is much louder but does not sound like anything is wrong [ with the fans] other than mac thinks its processors are about to ignite..

Sound familiar to anyone? I've been shutting it down this way for years. When the above behavior is in play I have to hold the start button in till it quits. Key commands do not work.

Kinda spooky.
