Your MacBook Air has a fixed amount of space available to use for your apps, files, pictures, and everything else that is generally accumulated over the lifespan of a typical computer owner. So when you find that you are running out of space for the files and programs that you actually want and need, you might start looking for ways to delete the junk files from your MacBook Air that you aren’t using and can safely remove.
The best and easiest way to remove these junk files is with the help of a program called CleanMyMac from MacPaw. You can visit their website to learn more about the CleanMyMac program and see everything that it is capable of doing on your MacBook Air so that you can start reclaiming your storage space from the junk files that are needlessly using that space.
How to Remove Junk Files from Your MacBook Air
Once you have downloaded and installed CleanMyMac on your MacBook Air, it’s time to start using it to delete all of the unnecessary files from your computer. The MacBook Air used in the images below is running OS X Version 10.9.5.
Step 2: Click the Scan button at the bottom of the screen. Note that it can take several minutes for CleanMyMac to find all of the junk files on your computer. The scan that I did on my MacBook Air found over 7 GB of “junk”, which is a significant percentage of my 128 GB hard drive.
Step 3: Click the Clean button. You may need to enter your MacBook password to give the program permission to delete some files. You might also need to quit some open programs. You will be prompted to do so if this is required.
Once the cleaner is finished running, you will have deleted all of the “junk” files from your MacBook Air. However, there may be another place where you can delete some additional unnecessary files. You may have accumulated some programs on your MacBook that you aren’t using anymore. While you can uninstall applications without CleanMyMac, they might leave behind some files. Continue below to see how you can use the CleanMyMac uninstaller to completely uninstall a program from your MacBook Air.
