Answer to: Why does my iMac shutdown halfway through loading on startup?Dan, I finally got my Firewire Cable from monoprice. I connected my iMac to my MBP and turned on the iMac and held down T. I finally got it to boot into to Target Disk Mode after about 5 tries. I was able to erase my boot disk in disk utility and install Yosemite back on to it. My iMac now boots up in about 10 seconds and is running great. I will install Temperature Gauge Pro to monitor and hopefully prevent any future issues. Thank you so much for the help!
