There's a bug in the Bluetooth®-stack of OS X® 10.8/10.9 in the context of pairing a Sony® PS3 BD Remote. OS X® 10.8/10.9 will ask you to enter a PIN code when you try to connect your remote control. This problem is known by Apple®.
If you pair your Sony® PS3 BD Remote with your Mac® for the first time
Use Remote Buddy's Setup Wizard to pair your remote control
Restart your Mac® directly after the pairing was successful, while the remote is still connected.
The remote should now work without problems.
If you've already paired the Sony® PS3 BD Remote with your Mac®
10.9 only: Try entering 0000 as PIN and reboot. If you're lucky, that was all you needed to do. If this does not solve your issue, please continue with the steps that follow.
First, we'll need to remove the Link Key of your Mac® from the memory of your remote control. Since this remote control can only store one Link Key, it's as easy as pairing the remote control with another Mac®. To do so, open System Preferences > Bluetooth on another Mac® and pair your remote with it.
All steps that follow should be performed on the Mac® that you want to use your remote control with.
Remove - if it exists - the entry of your remote control at Remote Buddy > Preferences > Hardware ® Bluetooth Receiver. The entry usually is titled "BD Remote".
If existant, remove the device "BD Remote" from System Preferences > Bluetooth.
Delete the Bluetooth preferences files by entering the following in Terminal.app and hitting return (Warning: this deletes all information about all paired Bluetooth® devices):
In order to automatically activate the Bluetooth® Receiver on startup, enter the settings, choose "Hardware", then click on "Bluetooth® Receiver". Finally activate the checkbox "Search for supported remotes on startup". Remote Buddy will then automatically look for remote control paired through the "Setup Wizard" on next startup.
