G'day Paul,
Without going into specifics, I believe you should pay attention to the following:
1. Hand control is not needed. Disconnect it, and make sure the mount is started without the HC present. The pointing data/tracking/motorcontrol/etc will be handled by SkySafari. Skysafari and the Wifi dongle will tell the mount everything it needs to know.
2. Make sure the current location, time and Timezone is set in Skysafari. This is easiest with your iPad, as it has a GPS and time data made available to skysafari. Presuming the MacBook has no GPS available, this must be done manually.
3. Manually move the scope to a known object, centre in the eyepiece, and then select the same object in SkySafari, then click "Align".
4. Repeat this a few times, with objects well separated throughout the sky, and you will have a good goto basis.
5. Look at "Slewing and Aligning":

6. Be excellent to Yourself.
