    LR CC 2015 5.7.1 running very slow on new iMac 5K


      Every LR CC I've used runs slow. When I use any editing tools, skip through history, try to select and apply presets, it's all slow and almost non responsive.

      Spinning wheel spins for a long time trying to render any command.


      Got a new fully loaded iMac 5K retina so can't see this as a hardware issue at all.


      Catalogue 320 RAW images (25Mb each file)

      Camera RAW cache set to Max 50Gb


      Processor 4 GHz Intel Core i7

      Memory 32 GB 1600 MHz DDR3

      Graphics AMD Radeon R9 M295X 4096 MB

      Storage 3TB Fusion Drive


      Can anyone please help?
