I have an Early 2011 MacBook Pro that has been working fine, until a few days ago. I tried to run a system update,that includes the following updates: iPhoto Update 9.2.1 HP Printer Software Update 2.8 MacBook Pro EFI Firmware update 2.3 I runs the update installs the updates and then hangs when it get sot "Moving Items into Place..". It just sits there, and does nothing. I then have to force quit the installer, and restart the machine, at this point it reboots as normal, but rolls it back to before the updates were installed. If I try to update again, same thing happens. One thing that I have noticed since attempting this install, is that my iPhoto no longer works. WHen I try to launch it, it tells me this"iPhoto cannot be opened because of a problem." I do have my iPhoto Library on an external drive. BUt the drive was plugged in during the updates. Can anyone help me to get my machine updateable again. Please help!
