Just received this device and installed it - works well when my iMac DUO is running but will not wake the computer from sleep. Option box for Bluetooth is grayed out. Seems simple enough until you try to get help from DLINK. After minutes on hold, I was transferred overseas to an apathetic agent with broken English who had little to no experience with MAC Tiger. Read me FAQ's and then told me Apple had to change their program settings to work with their adapter. If this wasn't good enough - then return the product. Sorry attempt at support - won't be considering DLINK for any future equipment needs.
