Not sure if it's due to the Wacom Pen and Tablet I have plugged into my MacBook Pro, but the history and brushes (eraser etc.) are very laggy and un responsive until going up to the top menu bar to select Undo etc.
Overall PS CS6 is fairly unresponsive in some features, was wondering if anyone noticed these bugs?
Yes, MacOS 10.10 currently has a lot of problems with tablets and trackpads, but mice seem unaffected.
Wacom may have a driver update to solve it, but some people report that downgrading the driver works better.
Please let Apple know what you are experiencing, so they can get any additional information they need to solve the bugs introduced in MacOS 10.10.
New Wacom drivers that have been released fix the brush lag issue, however still haven't herd back from Apple on CS6 top menu's being delayed/laggy after reporting the bug.
