Good evening. I have a question for you all. Recetnly, my iMac 27" i7 has begun hanging in the most bizarre fashion. It usually seems to happen when I wake the computer from sleep or screen saver, but that isn't always the case. What will happen is that when I get to the computer, Mail will show symbology that indicates it is not connected to the Internet or Safari, upon booting, will not open a webpage (it sits on a white screen rather than delivering an error). I'll go to quit one of the offending programs, and it will not quit and beach balls instead. I then right click on the dock to trigger a force quit, and the force quit does nothing and the dock beachballs. I try to restart/shut down, and nothing happens. Thus I am forced to hard restart. Conversely, I am sometimes able to get an offending program to force quit, but the rest of the computer (anything I click locks up) beachballs leaving me to hard restart. I find when this happens, my first instinct is to click system prefs and go to networking, where when I click networking, it locks up. Then I have to hard restart Finally, there are times when it does respond to a restart request. It will go through the restart process up to the blue screen at the end, where the little spinning doohickey will appear and stay there indefinitely, forcing me to hard restart. It didn't seem to happen before I got my iPad but happens about every other day now. At first it seemed to happen after I had my iPad charge from my computer, but now it seems to happen regardless. One time it hung while syncing with my iPhone and required me to restore it since the phone got messed up. I've done everything I can think to do to get to the source of the problem and I can't figure it out. I've looked through logs and didn't see problems (granted, I don't know if I'm looking at correct logs or if I'm looking for the right events). I have repaired permissions, and that seemed to help but not fix the problem. I bridge my iPad to my computer through Internet connection sharing, since I have an Ethernet internet connection. I created Automator work flows to turn it on and off (and AirPort) as I never leave it on when not using it. Does anyone have any bright ideas?
