Hi Vero, thanks for your reply. There's an error in Console: osascript: Performance: Please update this scripting addition to supply a value for ThreadSafe for each event handler: "/Library/ScriptingAdditions/SIMBL.osax" I have SIMBL installed because I use the SafariStand plugin which give me favicons in Safari tabs and daily download folders. Will probably in the future have to do without it.
I have setup a hotkey (F15) with the System Command "Sleep". But after upgrading to Mac OS X Yosemite 10.10.4 this no longer works. I've tried other keys with no success. Other System Commands like "Screen Saver" or "Show Trash" working as expected. Any ideas to solve this. Thanks Thomas
