      Hi guys.

      I have the most powerful iMac 5k late 2015 model you can buy and i have personally upgraded it to 64gb RAM.

      so that is the top i7 processor, 4gb graphics, 500gb SSD


      Lightroom runs like a dog.  RAM usage is fine.. anywhere from 3gb-7gb

      however CPU consistently runs up to 400-800% and my cooling fans go crazy.


      Not to mention the lag doing anything.


      what do i do?
