  • Macbook pro shutdown hangups.

    My Macbook is intermittently hanging upon shutdown. Anyone got any clues?. (1 year old. Still runs rings around my PC laptop friends.) Didn't see any red flags in the logs.

    Have you run Onyx or any other maintenance utility lately? May not help, but it wouldn't hurt, and it's a basic troubleshooting step in these situations.

      That depends on when it is hanging. What does the screen look like when it hangs?

        Actually the screen is blue with the busy icon running. (And, no, I didn't mistake a PC for a Mac.) For an OS that shuts down quickly, this is very unusual.

          Mine takes a random amount of time to shut down. Sometimes it's almost immediate and sometimes it takes 30 seconds or more. I suppose it's trying to write some temporary files and such things.

          If that's the case, then you might have a corrupt file somewhere. Do you have Diskwarrior?? I'd start with Repair Permissions first as it might be a simple registry type thang..

          Keep us informed..!

            Here is what is supposed to happen when you choose shutdown or restart.

            The loginwindow process logs out the user, tells the kernel to quit remaining system processes, and then force-quits processes that don't respond to the initial quit. After this, quit launchd and shutdown the system. If you chose to restart, then at this point the startup process is invoked.

            If you are getting to a blue screen with the spinning gear icon, my guess is that the kernel is waiting for processes to quit and they aren't quitting, at which point it is supposed to force-quit those processes. if they don't respond to a force-quit, then you could hang at this point. The next time you get one of these hangs, look in system.log for when you force-restarted your Mac for any clues. It's difficult to describe what these clues will look like, but something might jump out at you, i.e. an entry that says "we are hanging here."

              Found an auto run program for HP's all in one printer that I have on the network. You can't really use the scanning feature without attaching it to the machine, but printing from all computers is fine on the network. It's looking like the HP software may have been the culprit.

                I've finally decided that resetting safari before closing it fixes the problem. Makes me suspicious that somebody has a script that is doing something that I don't want done on their website. Guess I'll have to give up porn.

                  That does sounds odd. Resetting Safari should reset virtually everything but maybe there is some crap going on in the modern Mac system that we're unaware of

                  Hociman seems quite 'deep system level' with a load of his comments so maybe he knows...

                  p.s. Download the latest version of Flash' for OSX. Jobs publicly/recently said it was the number one cause of OSX crashes and considering your issue may be Safari related, it's worth a go flushing it out and getting the latest version on board. Probs worth running Firefox for a bit and seeing if the issue is the same. If so then i'd be tempted to point my finger towards Flash..

                    Try updating Flash and using Firefox instead of Safari and see if the problem persists.

                      Resetting Safari isn't really doing it. So far the only thing that's working is logging off and then shutting down. So I still don't know what the problem is. May just rebuild the OS.

                        Just so I am clear, if you choose Shut Down... from the Apple menu while logged in, you get a hang at the blue screen with the spinning gear, but if you choose Log Out from the Apple menu, then click the Shut Down button at the login window, you don't get a hang on shut down?

                          All I can say is that the problem is intermittent. It hangs sometimes no matter how I shut down. When it's in the dock, I have to remove it to force a mechanical shutdown. One time, I didn't quite get it shut down and put it in my laptop case. It got pretty warm. (And the battery was still reading over 80 % after rebooting it.) The whole thing is a nuisance if you ask me.

                            Have you tried another OS X user account? If the problem persists across user accounts, it is a system-wide problem. If the problem does not occur with another user account, then there is something going on with the affected account.

                              For what it's worth. They just released 10.6.8 so it might be worth updating and seeing if that fixes anything. 10.7 is out very shortly and is going to be cheap and it could fix your problem..
