How to Clean MacBook Files

By Michael Jones

If you bought your MacBook new, it came with a CD that allows you to format the system and get rid of unwanted files. If you don't have the CD, you'll have to delete the unwanted files manually. If you're looking to sell your MacBook, or have to return it to its owner, it's probably wise to get rid of everything that you installed on the system. This could be a time-consuming process, but it's certainly worth it. It can increase the speed and performance of your MacBook.

How to Clean MacBook Files

Step 1

Back up any files that you want saved. This can be done in a number of ways. Probably the easiest way is to first insert a USB flash drive into the USB port on your Mac. Then click and drag the files you want to back up to the folder of your flash drive.

Step 2

Go into the Applications folder and highlight all the programs you want to delete. Press the "Apple(Cmd)" button + Delete. This will send all highlighted items to the trash.

Step 3

Go to your Trash Can and empty its contents. This will get rid of your files.

Step 4

Open Safari and go to the preferences. Delete all cookies and temporary files.

Step 5

Open the Applications folder and go to the program called Keychain Access. This program will allow you to delete all the passwords you have saved. Make sure not to delete the computer log in, if there is one.

Step 6

Double click the hard disk icon, open up the Users folder, and open the folder with your name. Go through all the folders and manually delete the contents that you no longer want.
