Running OS X 10.10 & Photoshop CC 2015 Legit license on official Apple Unibody MacBook hardware. Nothing is pirated or on a hackintosh.
Problem occurred after both OS X & Adobe Creative Cloud updated. My entire work area (everything between rulers & scroll bars) is black. I know it's not just the canvas bounds. As I have zoomed out to the point the image should be nearly invisible & everything is still black. The color picker tool & swatches panel also falter.
Tried each Drawing Mode setting, disabling use of graphics card, multiple memory usage allowances, moving the cache/scratch to SSD, tried each image mode setting & bit depth. Also manually did a system wide driver(kext) update. No difference has been made, doesn't matter what settings are used.
After trying everything else I can think of I uninstalled all 3rd party utilities & drivers. Slowly introducing them back into the system. I believe the problem is linked with the driver for my tablet.
Uninstalling the driver resolves the graphics issue, reinstalling restores. So great right, just uninstall the driver & use Apple's stock tablet driver. Unfortunately I lose use of the shortcut keys on the tablet edge, pressure sensitivity settings & proper multi-display support. Though the stock driver for OS X may work. It's not as functional as the official Monoprice driver which used to work in Photoshop & still does in all other software.
What I would like to know is how common a problem this is. I've found some scattered information around the internet about mouse/pointer drivers causing black screen issues. Mostly for Windows/Direct X & not OS X mind you. At any rate none of the "fixes" mentioned work for my tablet & setup.
For the time being I've contacted Monoprice & gone back to stock Apple driver for Photoshop & reinstall when texturing inside of Blender. I would greatly appreciate if anyone had any insight they could share.
If there is simply nothing left to do. Are there any recommendations for a different tablet? One that is known to work still.
