    Lightroom is making my iMac shut down!


      I'm having a major problem with my IMac just randomly switching off and I have narrowed it down to only happening when I am in Lightroom. It was happening in Lightroom 4 and last week I upgraded to Lightroom 5 and its still happening. My Mac will not turn on again until I unplug it and wait for around 20 seconds. I've deleated all my downloaded presets, just in case it was them but its still happening! Please help as I can't get my work completed!!
