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?

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,

Lightroom Classic 2015.4 version, lightroom worked before well. A month ago I reordered and since on the MacBook Pro (mac OS High Sierra 10.13.3 version). Here are some crash reports:

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'm having the same problem too. I have a 1017 Macbook pro with Catalina 10.15.5. The lightroom box flashes on the screen briefly but never opens. I tried trashing the playlists. That doesn't work.
