Keep Podcasts on Mac, not on iPhone
I like to keep a lot of podcasts backed up on my Mac, not on my iPhone. I used to just subscribe on the Mac, then sync through iTunes.
Now, it seems that the podcasts I want on the Mac get subscribed to on my iPhone and I don't have room for them. So when I turn off the subscription on the iPhone, it gets turned off on my Mac.
I have lost the ability to listen to several of the podcasts that are available for two weeks only, because this downloading has stopped on my Mac.
How do I download Podcasts to the Mac only, and not download them to the iPhone?
