  • The May 2019 Lightroom updates are now available. There's a brand new slider called Texture, available across the whole family of apps. Lightroom Classic includes a new tool called Flat Field Correction. Lightroom (cloud-based service) has lots of big improvements including cloud trash, invitation-only web galleries, improved chromatic aberration removal and more. The Missing FAQ and Edit Like a Pro eBooks are already updated for the changes. You'll also notice the CC's have disappeared off the end of the names, so we've updated the forum names to match.

Welcome to the forum.
In the Help menu is a submenu item called "System Info..." Can you copy and paste that into a reply here?
The ideas that I'd like to explore are:
  • Not enough RAM
  • Not enough free space on the primary drive for LR temporary files.
  • GPU acceleration turned on and the GPU driver is out of date or unsupported.
  • Failing memory banks.
Did you successfully run LR with Lightroom Classic CC v8.0 or earlier?
Have you considered update the OS to Mojave (10.14)?
