Today I spent 3 hours on the telephone trying to figure out what was wrong with my new CS6 brush cursor which was twice the size of the brush effect, resulting in poor control of the brush function with a mouse. I run a MacPro Desktop with Mountain Lion. The tech and I went though a full 2 hours of painful searching to find out that the setting of the Cursor Size Slider in Accessibility within Apple System Preferences reaches through into the CS6 application and messes up the cursor in Photoshop. This does not happen in CS3. I just changed over yesterday and I did not have this problem. The tech said he would write it up. Maybe a patch in a future software update??? At any rate, be warned, you who wear glasses and have set the system's cursor size up so that you can see it better--it fouls up your brush cursors in CS6, and it is not readily apparent what the problem might be! I post this just so the info can get out on the blogs. If you are a member of the Adobe Photoshop users group anywhere, you could help by posting for unaware persons to find with a search engine until Adobe addresses this issue, as it can be a real "head scratcher" if you just stumble into it by installing CS6 on your system under your own user name.
