After updating to Mavericks there seems to be an issue with my computer. When I run the script I get this message; This script utilizes the built-in graphics user interface scripting architecture of the Mac OS x which is currently disabled. Click the check box “Enable Access For Assistive Devices” in the universal access preference pane and run script again. Well, for the life of me, I can't find any check box the says “Enable Access For Assistive Devices”. Does anyone know where I can find this check box?
