Lightroom Classic 9.x and Lightroom Classic 8.4.1 work with macOS 10.15 (Catalina) but have these known compatibility issues. You may want to remain on your current version of macOS until these issues have been resolved.
Adobe strongly recommends 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, and so forth).
If you do encounter issues not already documented here, feel free to report them on our feedback site.
No, older versions of Lightroom Classic were neither designed nor tested to work on macOS Catalina. They are not supported in any way for use on macOS Catalina.
Adobe does not recommend that customers using old versions of Lightroom Classic upgrade to macOS Catalina.
Older versions use 32-bit licensing components and installers. Therefore, they cannot be installed and activated after upgrading to macOS Catalina. Although upgrading to macOS Catalina with an older version already installed on your computer may allow the app to function in some capacity, you will not be able to reinstall or activate the app after the macOS upgrade.
Before upgrading to macOS Catalina, you may uninstall the older versions as the uninstaller will not work after upgrading. If you have already upgraded to macOS Catalina, you can use the Creative Cloud Cleaner Tool to uninstall older versions.
Adobe has discovered the compatibility issues listed below with running Lightroom Classic 8.4.1 or later with macOS 10.15 (Catalina).
When you try to import photos in Lightroom Classic, you get one of the following issues:
- Unable to import images from external drive.
- Unable to detect card/camera.
- No progress bar.
You might face these issues if Lightroom Classic does not have permission to access the removable drives. To resolve this issue, navigate to System Preferences > Security and Privacy and make sure that Lightroom Classic has required permissions to access files and folders.
Lightroom is not able to detect Nikon cameras when the camera is turned ON after invoking the Start Tether Capture command.
First, make sure the camera is turned ON. Then, select File > Tethered Capture > Start Tether Capture.
We are working with Nikon to correct this problem.
The Lens Profile Creator is currently 32-bit, but we are investigating updating it to be a 64-bit utility.
