Apple has never released a stylus that works with Mac trackpads, even though the company has released other stylus products for its iPad and Apple Pencil. The main reason for this is because Mac trackpads are designed to work with fingers, and not stylus pens. However, some third-party companies have released stylus pens that are compatible with Mac trackpads. These third-party styluses use pressure sensitivity and simulated finger movement to replicate finger-based interactions. While it is unlikely that Apple will develop a stylus that works with its Mac trackpads, users have other options if they want to use a stylus with their Mac.
