I don't know why.
- My entire iTunes Library is on my Mac mini
- I've entered the same Apple ID in iTunes' Home Sharing on both computers
- My iPhone and iPad can use Home Sharing from my Mac mini's iTunes
- I open iTunes on my MBA and Home Sharing does not appear in the left sidebar
- I tried removing and re-entering my Home Sharing credentials on my MBA. This did not help.
I've searched around for a solution but found nothing. Does anyone have any experience or suggestions?
