Set separation alerts in case you leave an AirTag or other item behind in Find My on Mac
In Find My, an item is an AirTag or third-party product registered to your Apple ID. You can turn on separation alerts for an item so you don’t accidentally leave it behind.
You can also set Trusted Locations, which are locations where you can leave an item without receiving an alert.
Important: Although you can view and manage separation alerts on Mac, you will only receive the alert on the device sharing your location—for example, your iPhone. See “Set separation alerts in case you leave an AirTag or other item behind” in the user guide for iPhone or iPad, or Locate an AirTag or other item in the Apple Watch User Guide.

on your Mac, click Items.In the Items list, select the item you want to set an alert for, then click the Info button

Turn on Notify When Left Behind, then follow the onscreen instructions.
If you want to add a Trusted Location, you can choose a suggested location, or click New Location, select a location on the map, then click Done.
