Set up Bluetooth sharing on Mac
Use Bluetooth Sharing settings to control how your Mac handles files exchanged between Bluetooth devices (for example, an Android phone). See Share files between your Mac and Bluetooth devices.
Tip: You can share files between your Mac, iOS devices, and iPadOS devices using AirDrop, Handoff, or iCloud.
On your Mac, choose Apple menu > System Settings, click General in the sidebar, then click Sharing on the right. (You may need to scroll down.)
Turn on Bluetooth Sharing, then click the Info button on the right.
Set the following options:
When receiving items: Choose Accept and Save to save all items sent to your Mac; choose Accept and Open to open the items; or choose “Ask What to Do” to decide what to do each time a file is sent. If you don’t want to accept any items sent to your Mac, choose Never Allow.
Folder for accepted items: Choose the folder in which you want to store accepted files. The default folder is the Downloads folder. Choose Other to select a different folder.
When other devices browse: Choose Always Allow to let devices browse your Mac, or choose Ask What to Do to manually decide what to do each time a device tries to browse your Mac. If you don’t want other devices to browse your Mac, choose Never Allow.
Folder others can browse: Choose the folder on your Mac that other devices can browse. The default folder is the Public folder. Choose Other to select a different folder.
