Itunes never stop updating podcasts
Since i Tunes 12, there has been a “feature” that acts as a bug to us.
One of which is old and hasn't been updated in a couple of weeks, and one of which is current.
When you uninstalled i Tunes, did you remove all Apple programs?
i Tunes, Bonjour, Apple Mobile Device Service, i Pod Helper, Quicktime there are a couple more too. Typically a greyed out episode in i Tunes means that the episode was not downloaded properly. In my personal opinion, there is no need for virus scanners.
In addition to releasing software updates across i OS, Mac, and watch OS, Apple today has released an update to i Tunes.
The update brings i Tunes to version 12.4 and includes the design tweaks that were initially rumored earlier this month.
