Hi there ghafaa,
The article linked below provides tips that’ll resolve most issues like the one you described, where you aren’t to AirDrop because your MacBook Pro doesn’t see any devices nearby.
Using AirDrop with OS X Lion, Mountain Lion or Mavericks - Apple Support
If you don't see nearby users in AirDrop
When you select AirDrop, OS X looks for other Macs that are close by and also using AirDrop. If you don't see someone in the AirDrop window:
- Make sure Wi-Fi is turned on at both computers. Although you don't have to connect to a specific network, Wi-Fi needs to be turned on to transmit and receive files wirelessly.
- Make sure that the recipient has selected AirDrop in the Finder. If you don't see this option in the Finder, refer to the Additional Information section of this article to make sure the computer is compatible with AirDrop.
- Try moving the computers closer to each other. AirDrop is designed to work within a range of approximately 30 feet (9 meters). If you need to send a file to someone further away, consider using File Sharing, iCloud or email instead.
Cheers,
-Jason
