I'm running a Mac with the newest OS X Mountain Lion.
I didn't have this problem before, but then I needed to enable the root user. Since then (just assuming, because it could be caused by something else) I can't download any content from the Android SDK Manager. It fails with a message (Permission denied). I'm able to do the update from the root user. That's kinda problematic. What can I do about it?
I had to delete eclipse, download it again and install all content all over on my standard account. Then it worked
