Summary: This post is about how to clean up and optimize your Mac. Your Mac is running sluggish these days. The lack of storage should be blamed in most of cases. What you need to do is to find out what is taking up so much space on your Mac and clean it up. Below you will see how to speed up your Mac computer.

To optimize your iMac/Macbook, it is crucial to keep your Mac clean and make sure there is enough space left for Mac system to run applications and load pages, especially for Mac computer that has been used for years with less than 10 % memory space left.

So how do you defrag a Mac? Regularly, you would try to empty your trash, remove old disk data such as images or documents, and clear out the useless downloads, etc. to optimize your system. That is exactly the correct way to speed up a sluggish Mac. However, manually offloading files from Mac's hard disk is not efficient enough because it’s not a simple task to what is slowing down your computer. With lots of Mac cleaners available on the internet, the key of optimizing your Mac is to choose a suitable Mac cleaner.

Now you can follow the below steps to optimize Mac performance:

Step 1. Launch MacMaster. Its homepage will show the system status of your Mac, including its battery state (MacBook only), total storage, available storage, used CPU, etc., which help you better monitor the status of the Mac system and detect any abnormal CPU, storage, or battery usage. Click on the "Clean" button and you can make a quick scan and then clean out your storage space on your Mac.

Step 2. Choose "Junk Files". You can clean up your login items or system junk files, such as junk files, system logs. One of the features I like is that this Mac cleaner app will scan out and detect the data which can be completely deleted without affecting the regular use of your computer. So you don't have to worry about the important file loss. If you want to learn more about the Junk files to delete, you can head to this page: Too Many Junk Files on Mac, Can I Delete in One Click?

Step 4. After using Mac for a period of time, there must be some unneeded photos, videos, audios, documents that are still occuping Mac storage. Select "Large & Old Files" or "Duplicate Finder" to scan out large or duplicate files on your Mac. You can preview the files before deleting. Only when you are sure that a files is unneeded can you tick the file and click Clean button to delete it.

Step 5. If you need to delete an app, it is not enough to just move the app to Trash. Choose "Uninstaller" on MacMaster and it will scan out all apps and related app data on Mac system. Click Clean to completely uninstall the app and delete its related data.

Step 6. To completely find and remove files on Mac and optimize Mac performance, you can try the next option, the "Shredder". It allows you to permanently delete the files you don't want anymore. But you should make sure that these files are useless, as the Shredder feature is so powerful and even a data recovery app for Mac can't help to recover the deleted data.

There is an video guide to make things clear. But please notice that this video is created in 2017 and FonePaw has gotten the MacMaster app upgraded currently, the interface is different (it does't change a lot but its appearance, so you can still refer to this video).

Your iMac/MacBook's performance should be significantly improved after the complete clean-up. If you have other trick to optimize iMac/MacBook's performance, feel free to share with other users below.
