    OSX Yosemite lightroom crashes and shuts down computer

    KerinFors Level 1

      I have lightroom 5 on both a 2012 MacBook Pro laptop and very new iMac.  Since upgrading to Yosemite, each of my laptop and iMac have crashed now when using Lightroom.  When I say crash, both computers have both suddenly shut down and restarted.  I've never had either computer crash like this before.  On each occasion, I was not doing anything in particular in Lightroom, just browsing through photos in the catalog (thought I admit it is a very large catalog of around 30,000 images. Just wondering if anyone else has experienced this, or know what might be causing it?
