Apple has released
Bluetooth Firmware Updater v1.0.2, designed to update the internal Bluetooth modules on PowerBooks and Power Macs. It’s also designed to work with external DBT-120 USB modules made by D-Link Inc. (revision B2 or later).
The update provides improvements in the update installation process, according to Apple, along with better performance when the Mac wakes from sleep and support for additional keycommands during startup.
What’s more, the firmware update improves connectivity between Macs and the recently introduced Apple Wireless Keyboard and Mouse, both of which use Bluetooth to communicate with their host Macs.
Apple notes that this firmware update is not applicable for Macs using other Bluetooth modules besides the built-in one included on some Apple hardware and D-Link Inc.’s DBT-120 rev. B or later.
System requirements call for the supported hardware as described above, Mac OS X v10.2.6 or later; Mac OS X Bluetooth v1.3 or later software.
