My Mac has WiFi connectivity, but I can't sync to my iPhone or iPod Touch.
There may be cases where you need to create a "Computer to Computer" WiFi network between your Macintosh and your iPhone. It could be that your Mac has WiFi capability, but you're not currently using it. Or, you might be using a public WiFi connection that will not allow the iPhone to see your Macintosh. You can get around this by creating a computer-to-computer network. To do this, follow these steps...
1. Open the System Preferences window on your Macintosh, click on Network, and select "AirPort" from the list on the left.
2. Click on the "Network Name" popup menu and select "Create Network."
3. Enter a name in the "Create a Computer-to-Computer network" window that appears. Then click OK.
4. You should see your new network name selected in the Network Name popup menu. The AirPort item on the left should have a green dot and say "Connected."
5. Close the Network Preferences window and launch Reunion on your Macintosh.
6. Open the Settings window on your iPhone and select Wifi.
7. You should see your new network listed under "Choose a Network." Select it and press the Home button near the bottom of your iPhone.
Reunion for Macintosh will now be able to sync with Reunion on your iPhone.
