Dim lights issue after MacOS upgrade to Big Sur (Version: 2015.5.1)

[Jonathan5D50]

Hi folks,

After I upgraded to MacOS Big Sur my L key shortcut to dim lights started giving me trouble, it darkens the entire screen as opposed to leaving the image as is. 

Has anyone experienced this before?

Version: 2015.5.1

Hi there,

Sorry that dimming the lights in Lightroom 2015.5.1 is not working after updating to macOS BigSur.

We tested this at our end and it appears to be working as expected in the Lightroom Classic v 10.1.1

We'd recommend that you update to Lightroom Classic as we have tested it on macOS Big Sur and it is compatible. Unsupported versions of Lightroom Classic were not designed or tested to work on macOS Big Sur (version 11). Older versions use 32-bit licensing components and installers and will not be able to be installed, uninstalled, or activated after upgrading to macOS Big Sur.

Thanks,
