I was just answering another question and was reminded of a new "feature" in Mavericks.
I used to have a number of small
Services that took no input but did something useful when tied to a keystroke. The perfect example was one to bring the Terminal to the front. Some of these required selecting a menu item in the application brought to the front such as
Bring All to Front.
Now it seems you need to grant "accessability" to every single app so that a universal keystroke will work if the Service uses the
System Events AppleScript library.
Anyone know a fix for this?
