Home share between iPhone and Macbook not working
Home Sharing does not work in that direction, meaning you can only share music stored on your Mac but not music stored on an iOS device.



The only way to view your iPhone music library on a computer is to connect it with iTunes and view it. This can be done in either of two ways:


Plug the iPhone into your MacBook with a dock connector USB cable. Open iTunes and find the appropriate item in the sidebar under Devices.
Plug in the iPhone and set up iTunes Wi-Fi Sync: Select the iPhone in iTunes, and under Options you should see something that says "Sync with this iPhone over Wi-Fi." Tick that option and apply settings. Once it's finished, unplug the iPhone (without ejecting it first) and you should see it remain in the iTunes sidebar. This will let you access its music wirelessly.
