I cannot pair my A1255 Alumnimum wireless keyboard to my macbook pro running 10.7.3. The keyboard is found in my bluetooth settings, but wont pair with it. The indicator light on the keyboard continues to do a blink-blink indicating it is ready to be paired. 

MacBook Pro (13-inch Mid 2010), Mac OS X (10.7.3)

    Try a couple of things (in order, quit if one fixes the problem).


    Reset the PRAM and SMC


    Delete the KB from the system, restart, and then see if it pairs.


    Trash a preference file ( and restart.

    You indicated the KB was paired with your brother's computer.  Bluetooth devices may only be connected with one thing at a time.  I have never had the problem, but it should have been unpaired/deleted from the other computer.

    This is an area that I have not had first hand experience and/or problems, so I am fishing a bit. This is some general stuff that might help...



    Unfortunately, I have no "brilliant" thoughts. 


    If you are near an Apple store, you could take it in to have them test it.

    With 10.7.3, there are two ways to pair a keyboard :

    1/ Keyboard Menu

    2/ Bluetooth Menu

    Did you try both ? Does it work with the 2nd one ?

    1.  Removed the already paired keyboard in the bluetooth menu list

    2.  Powered off my ipad (which i had previously paired this keyboard to

    3.  used the bluetooth menu to pair with the (generate new passcode option)


    worked as soon as i powered off my ipad (it was in my laptop bag)

    any luck with this issue anyone I just got found a a1255 at a garage sale but it keeps blinking and does not pair even when it is detected and that mac tell me to enter the pin

    Here's how I solved the same problem described. Believe it or not, you must enter a paircode/passcode on the keyboard so  the connection will be allowed. Here's how:


    1) Put your mouse on the Bluetooth menu bar (top of my AirBook),

    2) Right click to bring up the Bluetooth menu,

    3) Move down to "Set Up Bluetooth Device...",

    4) A wizard will pop up and the keyboard should be listed,

    5) Select the wireless keyboard,

    6) Your Mac should then display a passcode that you should type in -(mine was seven digits, not the normal "0000" used for Bluetooth devices such as a hands free headset). DO THIS USING the wireless keyboard that you're trying to connect (NOT your iPad or Mac),

    7) Press enter.


    This procedure should work, and I don't know why this paircode step does not appear when trying to pair the keyboard using the Keyboard section of System Preferences.......


    Hope this helps,

    Well DUH ... The pin code does show, however whatever I enter on the wireless keyboard.. it seems either all keys or the return key is not working, cuz no matter what i type on the wireless keyboard, it still says cannot pair after 20 30 seconds or so....

    I just successfully paired my A1255 with my computer.


    I couldn't get it to pair with the passcode (passcode options, in the setup bluetooth device menu) set to '0000' or auto-generated (auto-generated made an 8 digit code).


    I remembered that I had to use a 4 digit code with my iPhone in my car, so I figured maybe it was a device limitation, and that the zero's messed it up too.


    I changed passcode to 1234 in the bluetooth settings.. and then I was able to enter the code on the keyboard and it paired. Good luck!
