PS 20.0.2, Bridge 9.0.2.219, ACR 11.0.112


MacOS Mojave 10.14.3, with Radeon Pro 750 graphics card (27in iMac late 2017 model)




When I open my raw files from Bridge> Open in CameraRaw > the Adjustment brush is not visible.


When I open my raw files from Bridge> Open > then the brush is visible


How can I correct this so the brush works when Open in CameraRaw?


(It used to work fine until the latest round of Adobe CC and Mac OS updates)


*And here's the kicker, it's not consistent. Sometimes it does work. And sometimes the brush will quit working after having worked .


But I can't find a pattern to the erratic behaviour!!


As I understand it, the first option opens it directly in Camera Raw, and the second opens the file via Photoshop's CameraRaw filter.


I have tried to turn 'Use Graphics Processor' on and off in the Camera Raw prefs and In PS Prefs>Performance.


I've also changed (tried check & un-check) other settings in PS>Prefs to try and increase performance and solve the problem.


I did find these links but still haven't found the answer -

Any suggestions appreciated (& thanks to this who may have tried to help last time I posted this.)


Thank you
