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.

Method 1: Try iTunes to Locate and Delete Duplicate Content

iTunes is actually a great helper on Mac. In this case, you can resort to iTunes as to find out and remove duplicate data. iTunes has a built-in feature which is for deleting duplicate songs and videos in your iTunes library. However, it's only available for contents in iTunes.

Step 1. Launch the latest version of "iTunes" on your Mac.

Note: If prompted to update iTunes, please do as prompted.

Step 2. Click "Library" option on the interface and go to "Songs" option on the left panel.

Step 3. Select "File" from the menu at the top column.

Step 4. Choose "Library" from the pull-down menu and click "Show Duplicate Items".

Note that iTunes will show you a sorted list of duplicates next to each other. You can go through the list and check out which ones you might wish to get deleted.

Step 5. Check out the duplicates and get it deleted.

Method 2: One-click Clean Music Files on MacBook Air/Pro

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 long time to scan duplicates. Then, please highlight the desired items and delete them.

Apart from iTunes, it's also recommended to try professional Mac cleaner as FonePaw MacMaster. It supports to clean up all duplicate files stored in your MacBook Air/Pro and features more than that. Why not give it a shot via a click of the button below.
