Mac and iPad share 10 cross-device features that, when properly configured, operate as a single unified system across two screens. The prerequisites are simple: matching Apple ID, active Wi-Fi and Bluetooth, Handoff enabled, and physical proximity. Get those right and Universal Control, Sidecar, universal clipboard, and real-time screenshot annotation with Apple Pencil all work without friction.
The video is worth watching in full because the author does not just list features. He shows specific workflows, including using an iPad as a Final Cut Pro viewer while keeping a research browser open simultaneously, and using Apple Pencil to annotate Mac screenshots directly on the iPad in real time via Sidecar. These are the kind of operational details that documentation skips.
The closing argument is pointed: you do not need Pro-tier hardware on either device to make this work. The ecosystem behavior is the feature, not the spec sheet. If you own a Mac and have been treating an iPad as a separate product, this video reframes the purchase case entirely.
