Have an Apple, Mac, or iOS tech question? We’ve got the answer. In this week’s Ask, we’ll let you know how to prevent your iPhone from automatically downloading recently purchased music when you connect it to your Mac.
I have a problem where when I connect my iPhone to my MacBook Pro, the phone has all of my recent iTunes purchases loaded onto it. These songs are not a part of the cloud as far as I can tell: I have all of those options disabled. I can delete them from my device, but as soon as a plug the phone back in, they re-appear.
It sounds like your iPhone is set to automatically sync music from iTunes when connected to your Mac. Fortunately, this is a very easy fix that will only take a few minutes.
To begin, plug your iPhone in, then open iTunes. Inside of iTunes, select your device from the Devices area from below the “Now Playing” area. Once the device is selected, click on the Summary section under Settings, and uncheck “Automatically sync when this iPhone is connected.” This will prevent any automatic syncing between your iPhone and your Mac.
To really be on the safe side, click on the Music settings from the sidebar for your device. In this area, you will see a Checkbox to enable or disable Music syncing. Ensure this option is unchecked, then click the “Apply” button, then click “Sync” to transfer the new settings to your iPhone.
Be sure to uncheck “Sync Music” under the music settings for your iPhone.
