De-duplicate Music Files in MacBook Air/Pro

By Emily Watson, Friday, Mar. 17, 2017

MacBook Air/Pro are of genius design. It's remarkably thin and light. Portable as it is, it's powerful at the same time. That's how Mac captures hearts of over millions of users. With the time goes by, it shows a less desirable performance gradually. Though Mac is running a system which is able to keep the device clean and secure, it is wearing out in some ways.

The directly perceivable signs are the increasingly smaller storage as well as the increasingly slower performance rate. We might intentionally or inadvertently create some useless contents like duplicates, especially music files in MacBook Air/Pro. In order to speed up Mac, you should clean up your Mac. So, how to clean redundant songs? Any ideas? No? Why not scroll down and read on.

Part 1: Intentional Duplicates vs. Accidental Duplicates

Normally speaking, there are two kinds of duplicate items, of which respectively are intentional duplicates and accidental duplicates. We can simply tell the difference between the two terms from their names.

We usually create intentional duplicates at times like:

  • Update iPhone/iPad/iPod with iTunes on MacBook.

  • Make multiple backups for iOS devices or Mac.

  • Copy important files as a backup or for remedy.

  •  ...

As for accidental duplicates, we create them without knowledge most of the time. For instance, as a big fan of music, I like listening to songs as if I was swimming in the pool of melody lit up with touching lyrics. Undoubtedly, I've downloaded and stored a large number of music files from sources, which are so many that I might download a same song over times. That's how my MacBook Air is running out of storage.

Part 2: Duplicate Items Might Cause Problems

Countless drops make an ocean. Though a song might not in an attention-catching size, what happens if there are hundreds of or thousands of songs? Duplicate files can lead to issues that you certainly cannot take your eyes off.

  • Deplete massive storage on MacBook.

  • Slow down the performance of your Mac.

  • Shrink the lifetime of MacBook Air/Pro.

  • Bother the user.

Actually, if iTunes is the only source where you purchase and download music files. Lucky to you. It's a cakewalk to remove duplicate songs via iTunes. Note that this method only works for deleting those from iTunes Store. Launch iTunes and click "Library" > "Songs" on the interface. Next, select "File" from the top toolbar and head to "Library" > "Show Duplicate Items". It might take a while to scan duplicates. Then, please highlight the desired items and delete them.
