See your podcasts on all your devices
You can see your podcast subscriptions, stations, and current play position on your Mac, iPhone, iPad, and iPod touch when you sign in with the same Apple ID on each device.
On your Mac: In the Podcasts app , choose Podcasts > Preferences, click Advanced, then make sure “Sync subscriptions across devices” is selected.
On your iPhone, iPad, or iPod touch: Go to Settings > Podcasts, then turn on Sync Podcasts.
If you have an iPod classic, iPod nano, or iPod shuffle, you have to sync your device with your Mac to add podcasts and other content to it. See Sync podcasts between your Mac and iPhone or iPad.
