Hoping someone can advise or help. I updated to OS X Mavericks today, and when it started up for the first time on the MacBook Pro Retina, it kept throwing up a window listing all apps and above it the question 'where is Spotify.app?', then the option to choose or cancel. However, pressing Cancel only did so for a few seconds and the window appeared again and again. I discovered that when I stopped Geektool running, the problem ceased and Mac operation returned to normal. I've never had Spotify installed or used it, as far as I know! Is there a problem with Geektool or a script? I miss using Geektool, so if anyone can explain what's happening and offer a solution, I'd be grateful. Thanks.
