Lightroom Not Opening on Mac

[AngelsTravels]

All of the sudden Lightroom on my Mac does not open. I get the "Adobe Lightroom Quit Unexpectedly" message....It's not even opening. I have the latest update 4.0 from the app store. Is this happening to anyone else? How can I fix this? Mac Os High Sierra 10.13.6

Yes I'm having the same exact issue. It was working the other day and now it's not opening. I have the same OS and latest update. Have you found a solution to this yet?

Same Issue. Mac OS Sierra 10.13.6 and lightroom wont open. I see that the latest update (Version 4.0) is not compatible with High Sierra; however, Adobe recognizes this so wont let me download Version 4.0, it automatically downloads the latest compatible Version for your OS which is 3.4. Still wont open. I even backed up my computer, cleared the HD, and did a factory reset, re-dowloaded everything and still not working. If someone finds a solution please share.

Figured it out. I deleted Lightroom from my computer, opened Creative Cloud, and dowloaded verision 3.4 and it is now working. I think for some reason version 4.0 was getting downloaded automatically and saying it was compatable even tho it wasnt.

So I have deleted lightroom from my computer and am trying to download in from creative cloud. I went online and got the lightroom intstaller, but the lightroom installer window is just a plane white window. What do I do now?

Version 4.0 going forward are no longer compatible with 10.13.

I'm in the same boat and will

need to upgrade my Mac £££:https://helpx.adobe.com/lightroom-cc/system-requirements.html

I was having the same problem. I logged into Creative Cloud and then allowed it to update. Now Lightroom is opening again!

I am having this issue with Mac OS Monterey 12.0.1.  Creative Cloud says my lightroom is up to date, but I cannot open Lightroom
