How do I sinc my samsung hd 8910 to my apple mac

If you are trying to connect using bluetooth you can browse the phone. Go to system preferences and then click on bluetooth at the bottom right of this window
underneath the plus sign is "show Bluetooth status in the menu bar", click on this and it will make it easier to connect to your phone the next time you want to connect. Now click on the plus sign (+) this will bring up the Bluetooth Setup Assistant. click on continue select mobile phone. The blue tooth will start scanning (please ensure that your blue tooth is switched on your phone and ensure that it is discoverable). Hope this helps.
