MacFuse is used by many programs, and some like I said are used to mount and browse the iPhone file system. If you have any installed then plugging in the iPhone will launch that program and in turn use MacFuse to install.Bearing in mind, I have the latest OS 10.8.2, the latest incarnation of MacFuse (and I've tried getting rid of it too which doesn't work)
When they appear - I press 'OK' and they all come back in front of any app I'm using
It only happens when I plug my iPhone in though!
It doesn't matter what program I'm running it will always do it!
