45 minutes before I needed to leave the house for the airport I go to turn off my MBP so I can pack it. No, Apple wants to install about 7 security and related MBP updates. I of course say ok. Come back for the MBP a half hour later and it's got a gray screen with a "No" symbol and the rotating image that is rotating. I wait 10 min and come back. Same screen. I come back another 10 min later and now I need to go, I have a plane to catch. I force a reboot and it starts up to the same gray screen with No symbol. So I close the laptop and put it in my back. An hour later after getting through TSA (always a pleasure) I get to a computer table and get the laptop out. Sure enough it's still running but it's hot as hell. I have an SSD drive I think I'm ok, except it's still got the update gray screen on it. So I turn on the tether in my phone and the MBP hooks up instantly. I'm thinking I brought my install disk so I insert it and kill the computer. Problem is it's the app disk. So I boot up with the C key pressed anyway. The computer starts like normal. BTW Update now says that I have no updates to take care of. And, now the laptop is cooled way down. Any ideas on what I should do next?
