# If a sync failed

If you see a message that your sync failed or if nothing happens when you try to sync, check the following:

- Make sure your computer or device is turned on, properly connected (check it’s USB or Bluetooth connection), and set up to work with iSync (it should appear in the iSync window). If you’re using a Bluetooth device, make sure it’s within range of your computer. If you’re using a USB device, unplug the device from your computer, and then plug it in again and make sure it’s properly connected.

- If you’re tying to sync a phone, make sure you sync it using the Sync Devices button in the iSync window. (You cannot perform a sync using the phone’s syncing feature.)

- If you’re trying to sync a phone using the Sync Now command in the sync status menu on the right side of the menu bar, make sure iSync is open before choosing the menu item.

- In iSync, choose Window > iSync Log to see detailed information about your latest sync. If a sync fails for any reason, a window appears listing the date and the errors that occurred. This same error information, along with any changes that were made to your computers and devices, is shown in the iSync Log window.

- When syncing some Symbian OS phones, you may see a message that iSync can’t communicate with your phone. If you see such a message, open the iSync Config application on your phone and make sure the iSync Agent is running.

- On some Symbian OS phones, if the sync is interrupted, you may not have responded in time to messages on your phone asking if it’s OK for your computer to communicate with your phone (if you don’t respond after a short time, these messages disappear and the phone sync is canceled). To avoid having to respond to these messages, you can authorize your computer to communicate with your phone in your phone’s Bluetooth settings. For more information, see the documentation that came with your phone.

- If you’ve installed third-party calendar or contacts software, it may be preventing iSync from reading the contact and calendar information on your phone. Disable the third-party software before each sync. For information about disabling software on your phone, see the documentation that came with your phone.

- If you cannot sync at all or are seeing frequent error messages, you may want to reset your sync history. Resetting the sync history deletes the information in the Mac OS X synchronization database on your computer (the place where all your sync changes are stored), and returns the sync settings for your computer and devices (in iSync, on MobileMe, or any other sync client you’ve used) to their original states. To reset your sync history, choose iSync > Preferences, and then click the Reset Sync History button.

- If you’ve changed your setup or any settings, try syncing again.

If your information still does not sync, you may want to “start over” by replacing the information on your device with the information on your computer.
