Another feature is Apple File System on iCloud Storage. You can use this to store documents, photos, and other data that you want to back up in the cloud. The APFS uses advanced technologies to offer faster access and more disk space. 

Apple Accessibility Features provide an array of options to customize your device and make it work better for you. You can use features like Voiceover, Zoom, AssistiveTouch, and more to be able to use your device with ease.

Apple Facial Expressions & Switches is an app designed to help people with disabilities, such as ALS, control their devices. It offers a variety of features such as face detection, eye tracking, and blink detection to help people with limited mobility or who are unable to use their hands.

The Apple Head Pointer Options are a set of preferences that allow you to change the way that the cursor moves in macOS. If you have an Apple Mouse, Trackpad, or Trackball, these can help you customize the cursor and scrolling behavior.
