For the tone curve fine adjustment, try holding down the Alt/Option key as you drag a curve point.
The brush size adjustment could more likely be a preference in the touch-pad setup, as it would for a mouse scroll wheel.
Same issue, even on version 6.7 and official release of MacOS Sierra...
Same issue here on my system (Sierra, latest official release). Tried to reinstall creative cloud, lightroom, drivers and so on. Still the same problem!
There is an other thread active here, with the same theme.
show me pls.
I'm having the same issue with curves now that I've upgraded to macOS Sierra. Anyone find a resolution yet?
nope dont think so 😕
Also experiencing this... I tweak the curve pretty much every shot... so this is a big deal for me. This frustrates, especially considering Adobe gave Sierra a green light at launch.
Same problems with the tone linear curve adjustment. Moving the corner points with any kind of accuracy is an exercise is frustration. Also, the color sliders don't work correctly when using the color cursor selector. The thing is, Camera Raw 9.7 and Photoshop work OK, no problems with those. Come on Adobe, I and others have paid our annual fee. Fix this.
Lightroom 2015.7, Camera Raw 9.7, Photoshop 2015.5 and Sierra
I was having a tone curve issue with LR 6.5 or 6.6 on El Capitan but updating to 6.7 fixed it. Still on El Capitan though.
Same problem with the tone linear Curve adjustment in Lightroom 6.7 on macOS Sierra. Adobe must to lunch an update.
There is no solution yet??? Adobe come on.. learn from Capture one
I can confirm the problem. macOS Sierra and using Tone Curve is almost impossible, very frustrating...
Same with brush sizes.
Waiting for Adobe to see this problem and solve 😕
Facing the same issue on the tone curve whereby its hard to control the points freely, ever since i updated to Mac OS sierra 10.12.1 and Lightroom CC 2015.7. Hoping to see this problem solve as soon as possible
I can confirm the same Issues. Adobe please fix it!!
Also have this problem it is frustrating.
stilll no solution...thats sick
Same issue here. Hope this gets fixed soon.
Not being able to use Tone Curve in LR 2017 on Sierra is so annoying I want to throw my workstation through the window. Please guys, check your updates more carefully. We depend on you with our professional lives.
p.s. Have a great day!
I can confirm, having the same issue with Sierra. This has been going on for a while and I'm sick of it.
Same thing here. Infuriating to say the least. Running MacOS 10.12.1 on Early 2013 MacBook Pro Retina. Please help Adobe...
I'm a little surprised that at this point there are only 22 replies to this. Makes me wonder how widespread this issue is and if there isn't something specific to our having encountered it.
I totally agree. Makes me wonder if a person just needs to do a fresh install or something? Or maybe a prefs dump? Those are such simple troubleshoots, however no one has suggested that at all. Very curious...
