After updating OS X it is sometimes necessary to trash the prefs. Start by quitting Lightroom. Launch Finder and on the menu bar click “Go” whilst holding down the Optn(Alt) key and choose Library. Open the Preferences folder and trash the two plist files relating to LR6 (see image below)
Then re-launch Lightroom.
N.B. Apple hides the user Library until the Alt key is depressed.
You may also want to make sure you are on version 6.7
Thanks for the guidance. I could only find the second file (Lightroom6.plist), which I have deleted. However I still can't open LR. Any other suggestions?
The only other suggestion is to re-install.
- In Finder go to Applications >> Utilities >> Adobe Installers and uninstall Adobe Lightroom.
- Download LR6.0 from the link below and validate with your serial number
- Download the LR6.7 patch
Again thanks for the suggestion. I'll try this (tomorrow) and see what happens.
