Yep, Mac. I've already followed those instructions. The latest OS X version, Mountain Lion, adds Gatekeeper to prevent unsigned apps from running. I had to change the setting to allow all apps to run in order to run Calibre; normally this isn't necessary, and I can just force open the app.

So, something is really broken with the Calibre app for Mac lately.
