Choosing the best Mac mouse for you will depend on a number of factors Firstly, you'll need one that's compatible with your device's ports, whether that be USB-A or USB-C. Alternatively if you have a modern MacBook that's short on ports, you may prefer a wireless mouse.
Also think about the size and shape of mouse you want, and whether you need any special features, such as a scroll wheel or extra buttons that can be programmed for specific tasks. Finally, consider how much you wish to spend, as the price of mice can vary wildly depending on how sophisticated you want your mouse to be.
