MacPilot is one of the many utilities crowding the market for managing low-level Mac OS X parameters. What sets MacPilot apart from the competition is its expanding library of hidden settings of third-party applications.

Like *censored*tail, TinkerTool or Onyx, MacPilot, can change low-level Mac OS X settings to customise your OS X experience. It does this through an interface from which the developers are working hard to remove the clutter, hardly surprising given the sprawl of options.

MacPilot also continues to expand its ability to change hidden settings in a large number of third-party applications. This helpfully removes the need to mosey into the terminal to type arcane 'defaults write' commands.

MacPilot is not cheap, but then it also isn't for everybody: you have to know what you're doing when you're fooling around with OS X's innards. MacPilot executes well on its premise. I have used *censored*tail and TinkerTool before, but MacPilot does it for me.
