I am running the latest build of Lightroom, 9.4,  (I am a Photography Plan Adobe Subscriber) and every time I try to launch Lightroom  clicking on the .lrcat file (which I have in an external USB drive), it appears to almost start bouncing about in my mac dock , the splash screen appears for a few seconds but closes and quits immediately.

 

I reinstalled the OS (High Sierra), cleaned all Adobe Apps with the Cleaner of Adobe, reinstalled the Creative Cloud Desk top app a couple of times, uninstalled and installed LRC again and again, reset LRC preferences as recommended, but nothing works and I am desparate!

 

Everything was fine till this morning. I musr admit though that I used DaisyDisk app to delete some files and I might have gone a little over zealous with it.

 

But as I mentioned, I reinstalled High Sierra, the OSon my Mac and all the Adobe apps to which I am subscribed...

 

Please help.....

By chance it there a .(DOT)lock file in the folder that contains that catalog file you are clicking on?

 

What happens if you Open LrC from the LrC icon in your Dock?

There's no .dot file in the same folder as the .lrcat file

If I try to start LRC from the icon in the dock, the same thing happens.

NOT DOT DOT ".LOCK" file!!!

 

I included the (DOT) to emphasize the DOT before the word LOCK.

 

Best of luck to you. I'm out.

Please try switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

Thank you, but...

This is rather impossible: The problem is I can't start LRC, it keeps on crashing after one or two seconds after clicking the LRC icon, so how can I disable the GPU??
