The choices for "When other devices beowse are as follows:
When Bluetooth Sharing is turned on, if you click on Bluetooth under System Preferences, you should see "On" and "Discoverable" checked and you should also see any other systems accessible by Bluetooth displayed; you will see "Not Connected" beneath other systems that are accessible via Bluetooth
When Bluetooth sharing is enabled on the system, you should see the device for which you just enabled Bluetooth sharing when you click on Bluetooth under System Settings.
After a few seconds, you should see a Pair button appear next to it.
A similar window will appear on the other system where I will need to accept the pairing request by clicking on the Yes button on that window to accept the pairing. You only have a few seconds to respond. When the systems are connected by Bluetooth, the status of the other system will show "Connected" in the Bluetooth window.
Once I'm connected, I can send a file from the second system, GSSLA15122293, in this case by double-clicking on GSOD000962737L in the list of Bluetooth devices. I will then see a Select File to Send window appear where I can select the file to transmit to the other system.
If I want to browse files on the GSOD000962737L system, I can right-click on its entry in the other system's list of Bluetooth devices and choose Browse Files on Device.
On the other system, I will be prompted as to whether I will allow browsing to the Public folder, if I have the default settings.
If I agree to allow browsing on that system, I will then see the contents
of the Public folder for the account, i.e.,
~/Public. I can drag
files and folders from that directory to a
Finder window on the other system by positioning the
Bluetooth File Exchange window and Finder window on
the screen so that I can see both. The file transfer speeds I've experienced
between the two example MacBook Pro laptops have been between 8 to 14 Kbs.
