With authorization, you can use Bluetooth File Exchange to browse the Public folder on the device, retrieve files from the device, and transmit files to the device when your Mac is linked to a Bluetooth® enabled device, like a phone. However, you can easy transfer files between Macs or between a Mac and another Bluetooth-enabled device using the following steps:

Enable Bluetooth:

Make sure Bluetooth is turned on for both your Mac and the device you want to send files to.

Pair Devices:

Ensure that your Mac is paired with the other Bluetooth device. You may need to go to “System Preferences” > “Bluetooth” and pair the devices if they are not already paired.

Use AirDrop (Mac-to-Mac):

If you’re transferring files between Macs and both are running macOS Lion (10.7) or later, you can use AirDrop.
Open a Finder window and click on “AirDrop” in the sidebar.
Make sure AirDrop is set to “Everyone” or “Contacts Only” in the AirDrop window.
Drag and drop the file onto the icon of the Mac you want to send it to.
Bluetooth File Exchange (Mac-to-Device):

On your Mac, go to “Applications” > “Utilities” > “Bluetooth File Exchange.”
Choose “Send File” or “Send Folder” from the “File” menu.
Select the file or folder you want to send.
Choose the Bluetooth device you want to send the file to.
