After upgrading to MacOS Mojave 14.0 and also the latest Lightroom Classic CC 8.0 (Build 1193777, Camera Raw 11.0), Lightroom is very slow on my MacPro 2015 computer.
MacintoshHD drive has 600GB of free disk space, restarted the computer and only running lightroom with most of the 32GB of ram free, tried disabling graphics processor within preferences also.
When I start Lightroom I notice my folder free is grey and there is scan going on every time that slows down the startup, then after that startup process is done, moving from one photo to another or doing simple menu selections or edits has a lag of a few seconds with the occasional spinning beach ball appearing.
As a last resort, I reformatted my MacintoshHD drive, reinstalled Mojave and then install all of my apps from scratch and Lightroom is still slow, it make no difference whatsoever to the poor performance.
Prior to the Mojave upgrade, Lightroom was fast so the issue is with some sort of incompatibility with Lightroom Classic CC on Mojave. My other apps are running fast on Mojave.
Any suggestions?
