When ever I turn off my iMac (AL mid-2007 running 10.5) it seems like it hangs during shutdown... It takes about 60 seconds to shutdown and after about 30 seconds it starts to show. It looks like this, except it still shows my wallpaper... (This is just an image I found on the web). I am not sure why it is taking so long to shutdown lately... I don't remember it taking nearly this long in the past... Here is a photo of everything that is running during shutdown and it still does it. (I usually try to close out of apps before shutting down). What do you think?
