For most people, a keyboard and either a mouse or trackpad is plenty to control a Mac. But people using certain apps, such as music and photo editors, benefit from more granular control. That’s where Palette ($99+), from the company of the same name, comes into play. A modular series of physical controls, it allows you to customize a unique work flow.
There are four different kinds of controls in the Palette system: a power module with a color display, a button, a dial, and a slider. The first gets plugged into your Mac via USB, and from there, the others can be arranged however you like. They simply click together, while a free app recognizes their position and allows you to set functions. The base package gives you each control in aluminum, and you can move up to more expensive packages with more modules and premium materials.
