It is far too easy to fill the Mac menu bar with clutter. This can be a problem on modern MacBooks, which have a notch in the middle of the menu bar for the webcam—install too many apps and you'll run out of space. This, and a universal dislike of clutter, is why there are plenty of apps to clean up your menu bar out there, but those apps also can cause problems. Some apps won't launch consistently if you enable them, for one thing, and they're also yet another piece of software constantly running on your device.
