I'm getting a dreaded message after forced shutdowns that my early-2016 5K iMac "developed a problem."  I'm sending the info to Apple, but it's happening more and more, usually with more intensive apps like FCPX and Lightroom.  It's gotten to the point that it crashes with only a few minutes of hard work, makes it useless at this point.  Apple wants my credit card number if they are going to stand by their product.  
Any advice?
