For Handoff to work on both devices, Guillermo needs to turn on Wi-Fi, Bluetooth, and sign in with the same Apple ID on his Mac and iPad. Handoff is a feature that allows users to start something on one device and then complete it on another. For example, Guillermo can start working on a Keynote presentation on his Mac and then continue annotating it on his iPad. To use Handoff, both devices must be on the same Wi-Fi network, have Bluetooth turned on, and be signed in with the same iCloud account. These are the prerequisites for Handoff to work. Turning on iCloud Drive or AirPlay is not necessary for Handoff. iCloud Drive is a cloud storage service that syncs files across devices, but it is not required for Handoff. AirPlay is a feature that streams audio and video from one device to another, but it is not related to Handoff.  References :  Use Handoff to transfer Keynote presentations - Apple Support ,  How to Set Up and Use Handoff on Your iPhone and iPad - How-To Geek
