Bit Issue - Step-like grades after new MacOS installation .

[Dr. Nikita G. Olenin]

There are strange 16-bit-like grades in Develop mode in Lightroom appeared after MacOS Sierra was installed. There wasn't that issue before. In Library mode that's all ok.

Maybe somebody met this problem and has a solution?

Grazie!

Could be a problem with your monitor profile. Select another profile (any profile will do) just to check if that makes it disappear.
