How to use Lightroom Classic with Monterey 12.7.6, the application don't open

Hi, ​@Whimsical_member5efe, you’ll have to find a copy of LRC 13 to 13.5. Those are the last versions of LRC that can work with Monterey. Sadly, I have no clue as to where you could access that version.

I’m going to assume that your current Mac is updated as far as it can go. At this point, I’d suggest you see if you can find a used Mac that will not be new, but can use a more recent OS and thereby provide access to a current LRC.

Sorry, that’s the best advice I can provide.
