I have paid my creative cloud membership and photoshop opens perfectly on my computer. Lightroom Classic however is not opening, it sends a lot of crash reports. Where is the problem?

Try trashing the LR saved prefs and re-booting. 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 and any other .plist files relating to LR6 (see image below). It is also worth cleaning up any plist files relating to prior versions such as LR5 etc.

Then re-boot your Mac and re-launch Lightroom.

N.B. Apple hides the user Library until the Alt key is depressed.

Are you sure you are running LR Classic? Do you have a subscription or perpetual license?

This did not work for me. Sadly, I'm in the middle of a huge photo shoot with many deadlines. Any other advice? When I try to open LR, I get a quick view of the opening page and then it disappears.

I've got the same issue and these plist files are nowhere to find in the preference folder. I upgraded from a Macbook Air to Macbook Pro (MacOS Monterey). When I open Lightroom CC it says "Adobe Lightroom Classic CC quit unexpectedly." Any updates to solve this problem?

To delete the preference file - use Method 1 in linked Adobe Help document

I had this issue. What worked for me was to trash the preferences as specified in this thread. But I had to create a new catalogue. Then I imported the photos from a backup of the old catalogue. The issue seems to have been the catalog I was using. Even though I back it up everytime I quit, have it check for integrity, etc.

I too have the Problem that Lightroom Classic won't launch. The Startup screen comes on, then goes away, then nothing. I have trashed the preferences files and reboot. But this didn't change anything. Any more possibilities for solutions?

I also have exactly the same problem.

I'm using Macbook pro 2016.

How can we tell if you don't give any more details, like the version of MacOS X you are using, the version of Lightroom Classic, whether Lightroom Classic did run before or never did, any error dialogs you get? Saving a crash report and posting a link to it might also help the technical people on this forum to suggest a cause.

Hi Johan,
