why can't I find airdrop on my mac book pro? I upgraded to lion?

AirDrop requires a computer newer than your MacBook Pro: http://support.apple.com/kb/HT4783

As I understand it the wireless hardware is the limiting factor.

Macs that support AirDrop in OS X Lion

If your Mac is the same as, or newer than, the models listed below, then it supports AirDrop.

• MacBook Pro (Late 2008 or newer)*
• MacBook Air (Late 2010 or newer)
• MacBook (Late 2008 or newer)*
• iMac (Early 2009 or newer)
• Mac Mini (Mid 2010 or newer)
• Mac Pro (Early 2009 with AirPort Extreme card, or Mid 2010)

* The MacBook Pro (17-Inch Late 2008) and the white MacBook (Late 2008) do not support AirDrop.

Actually Airdrop is supported on Older macs, but is not visible; if you want it to be visible follow my steps:

1. Open Terminal

2. Insert the following command:

defaults write com.apple.NetworkBrowser BrowseAllInterfaces 1

3. Once complete insert the next following code: killall Finder

4. This should have fixed the issue, to test this goto Desktop>Menubar>Finder>Go>Airdrop

I hope this helped 🙂

How do I do 1. Open Terminal??

Ok you are going to go to spotlight (the magnifiying glass as top right-hand corner of display) and then type "Terminal" it should pop and the complete the instructions listed above. I hope this helped 🙂!!! Have a nice day!

Awesome!

Yes! Thanks a lot!

I have an older Macbook Pro model 3,1 running OSX 10.9.4

I too cannot find Airdrop to use with bluetooth to share files on my iPhone5

I executed the 2 TERMINAL commands you show in this post, but cannot locate airdrop using your suggestion, or using spotlight.

Any additional thoughts ?

Also, the bluetooth connection does pair my iPhone 5 with my Macbook Pro, but after a few seconds, the an error message pops up on the iPhone 5 saying there is a problem with the computer.
