GearBox Helper is what is known as an Application Agent. This is a program that runs independently for each logged user on a Mac OS X system and enables each user to have their own individual preferences for GearBox so that if another user changes, for example, the footswitch settings of the UX2, when you log in, your settings will not have changed. The only time it’s active is when the system detects a UX2 connected to the system, in which case it loads the correct preferences for the logged user and then goes back to sleep, so it’s not unnecessarily tying up any system resources.
