All- Have been the owner of a macbook from June/July 2008 17inch bought new from apple store. I ran update like 2 weeks ago, it hung I powered off. Had to, it was going nowhere, when this happened every shutdown after this does not fully complete. Basically its starts to shutdown backscreen goes grey and then there is the dial thing that spin over and over. I left for a few hours no go. The only way to shutdown is holding the button. No other issues but this, it happens if I am logged in or wife under her account. I went to applications fix permissions, fix disk. Some permissions were fixed however didnt resolve it. When I did fix disk it said it is ok. I ran the updates friday and was unsuccessful. It downloads install but gets stuck initializing SMC never completes even with core. Any suggestions? I really dont want to reinstall everything. It takes forever and nothing is wrong here. Well other than the shutdown issue.
