    Lightroom CC freezing when using Adjustment Brush


      I recently discovered the power of the Adjustment Brush to dodge & burn my RAW photos. As I progress through a photo edit though, my Mac becomes slower and hangs with the beach ball. I upgraded my RAM from 8 to 16 GB and upgraded from a 750Gig HDD to a 1TB SSD, but it still hangs when I get into an edit. My computer is a MacBook Pro 13" (Mid-2012), Processor: 2.9 GHz Intel Core i7, Memory: 16 GB 1600 MHz DDR3, Graphics: Intel HD Graphics 4000 1536 MB. In Lightroom Preferences, under Performance, I get an error message when I click Use Graphic Processor: "Graphic Processor acceleration has been disabled due to errors". Is anyone else having this problem? It's driving me crazy. Surely I don't have to buy a new, more powerful Mac just to use the Adjustment brush properly?
