Hello, everyone! Ever since the most recent security update (as of June 4, 2011), my iMac (2.8 Ghz Intel core i7) freezes on a blue screen during start up when I have my USB peripherals plugged in, as well as my Firewire Time Machine drive. The only way I can get the iMac to successfully start is by unplugging everything, starting the computer, and then plugging the USB and Firewire externals in. Has this happened to anyone else, and how can I resolve it?





iMac 27" Intel core i7, Mac OS X (10.6.4), 8 Gb RAM
