Lightroom Classic ver. 12.2.1 does not open on Mac mini M2 Pro

Report · Mar 22, 2023

Lightroom Classic ver. 12.2.1 does not open on my Mac mini M2 Pro - It was working today but would not sync all my photos (I experience this issue virtually every time I return from photo shoots) from Lightroom CC. When it wouldn't sync, I closed the application and then tried launching it again. It went through the motions of opening but did not complete it. I tried a couple of times and then deleted the app, turned the computer off and then back on and the reloaded it. Lightroom Classic still doens't launch. Does any one have a fix for this iss

I called Apple Tech support today and explained the issue. He had me go the Activity Monitor. Then under CPU I found Lightroom Classis was running, but not responding. I clicked on it and then chose the "Force Quit" option. I then chose "Disc" and looked for "Lightroom Classic" there but it wasn't. If it had been I would have clicked on it and "Force Quit" it there too. I then shut down the Activity Monitor. Then successfully launched Lightroom Classic.

Note, this is just a work around. The issue is not fixed but this gets around it. Hopefully Adobe is monitoring this chat and will take a look at what's the issue with LRC 12.2.1. I also need them to figure out why LRC doesn't sync with the cloud.

I'm having a similar problem. The Lightroom splash screen appears and then the Lightroom application stops responding. On another thread, I saw a link to this page: https://helpx.adobe.com/lightroom-classic/kb/lightroom-not-launching-after-splash-screen.html

On the page, it says to update to the lastest Mac OS and also try renaming the SLCache and SLStore files. I updated my OS, but that didn't solve the problem. Now I want to try the second solution, but I can't find those SL... files in the location stated on that page (System Library/Application Support/Adobe). Does anyone know where to find those files in Mac OS 13.3.1?
