I have Lightroom 5.7 (not CC) on a Mac. The adjustment brush is not fully working. It will show up as a circle and allow me to "brush," but won't show mask overlay when the box is checked or change exposure or any other custom setting I change it to. My updates are up to date on my computer. I have closed Lightroom, restarted my computer. Suggestions?
If either density or flow is set to zero, set them to 100 and try again.
of course I have maxed them to 100 or -100 to try it. no luck. I just posted this update The adjustment brush is not responding at all (using any effect) for me. It also won't show selected mask overlay. This has been true in Lightroom 5. I thought it would magically work if I upgraded so I downloaded the free trial of the latest Lightroom CC and on my new MacBook pro no less. There is no change though. The brush still won't work. Additionaly suggestions?
