Adobe has discovered the compatibility issues listed below with running Lightroom Classic and Lightroom CC (and earlier) with macOS 10.14 Mojave.
Adobe strongly recommends that customers update to the current release prior to updating to macOS 10.14 Mojave. Older versions of Lightroom Classic and Lightroom CC were not designed, nor extensively tested to run on macOS Mojave. Additionally, we strongly recommend that customers do their own testing on a non-production partition to ensure that new operating systems work with their current hardware and drivers (printing, etc). You may wish to remain on an older version of the OS that is compatible with prior versions of our software.
If you do encounter issues not already documented, feel free to report them on our feedback site.
