Transferring data from old mac to new using migration assistant

If you were using Wi-Fi, please stop it by restarting the computer. Then connect the Time Machine backup from the old computer to the new computer using a USB cable and then launch Migration Assistant on the new Mac. Why do it this way, simple it works 100% of the time!!!!!!!!!!!

You only need an adapter, you can find them on Amazon for about $9 or you can visit your local Best Buy and get one.

Are you transferring over Wi-Fi?
