How to Clean Mac Hard Drive Manually

If you never performed an automatic or manual system cleaning — it means that your Mac has been collecting unnecessary files and clutter for years. You can quickly clean up your Mac with these easy steps.

1. Clean up cache

You’ve probably heard “Remove your cache” as a web browser troubleshooting tip. In fact, your Mac stores a lot of information in files called caches, allowing fast access to that data and reducing the need to get it from the original source again. Unfortunately, those files take a lot of space on your Mac, and instead of speeding things up, they slow your computer down. Therefore, if you want to give your system a boost, clean your Mac from the cache files.

There are two ways to do that: you can delete them manually or use a MacBook cleaner like CleanMyMac X to do the job for you. Of course, the second way is an easy and fast one. However, if you decide to clean up the cache manually, check out a comprehensive guide on “How to Clear Cache on a Mac.”

2. Uninstall apps you don’t use

The applications you’ve installed on your Mac take up space, of course. And over time when your Mac becomes full of different apps, it may start running slowly. How to clean MacBook? In the first place, you need to remove the apps you no longer use or need. To do this, right-click on the app you want to remove and choose Move to Bin.

You may be surprised to find out that sending an app to the Trash will not uninstall it completely because the app leftovers still remain on your Mac taking up a lot of storage. So, if you want to be a responsible Mac user, you need to uninstall applications the right way. Here’s a step-by-step guide on “How to Uninstall Apps on a Mac.”

Extra step: Trim down your login items

Login items are applications that run automatically upon startup. Nowadays, every second app tries to become as prominent as possible and get into your Login Items. First of all, you may not even know what they are (not all of them appear in the Dock). Secondly, such apps consume memory. That's enough reason to get rid of extra login items you don't need.

  1. Open System Preferences.
  2. Go to Users & Groups.
  3. Choose your nickname on the left.
  4. Choose the Login Items tab.
  5. Check startup programs you want to remove.
  6. Press the “–” sign below.

You’re done.

3. Clean out useless duplicates

Computer

Identical photos, music tracks you’ve added one time too many, saved and re-saved PDF files… all of that sits on your Mac and gobbles up storage. The storage that could be used for better purposes.

So how do you quickly weed them out? The fastest way is to use Gemini 2: The Duplicate Cleaner.

  • Download and launch the app
  • Click “Scan for Duplicates”, and watch as it quickly fetches them from different corners of your Mac.
  • Once the scan is done, hit Review Results and check which copies you want to remove.
  • Click Smart Cleanup to delete everything you’ve selected.

That's it. Now your Mac should be completely duplicate-free.

4. Empty the Trash

Even though you’ve deleted the files, they reside in your Trash bin taking up a lot of storage on your Mac. They are just waiting to be removed completely. If you want your precious hard drive space back, you need to empty the Trash.

Here’s how to clean your MacBook from the trash:

  1. Click and hold on the Trash can icon in the Dock.
  2. Click Empty and then Empty Trash.

The process is quite simple, right? There is even a more effortless way to clear Trash. CleanMyMac X scans your Mac for junk and lets you remove all trashed files. To do that, launch CleanMyMac X and press Scan. When the scan is completed, click Review Details to see what exactly CleanMyMac X has found.

I’ve already cleaned Bin a couple of weeks before, but over some time, almost a gigabyte of trashed files has accumulated. Now, I can simply click Back to Summary and then Run to clean Trash and system junk.

5. Reduce clutter

Apple has already thought about the clutter that can be generated on the Macs and provided a possible solution. Here’s how to reduce clutter on your Mac:

  1. Go to the Apple menu.
  2. Choose About This Mac and then Storage. Here you can see how much free space is left on your computer.
  3. Then click Manage.

Here’re some recommendations for saving space on your Mac. You can choose Review Files to examine apps, documents, and other files that are stored on your Mac.

You can choose any file in every category (Applications, Bin, Documents, etc.) and click Delete to remove it and optimize space. Look through other recommendations and make the necessary changes to use your Mac’s space more efficiently.

6. Delete large and old files

It has always been a rule of thumb among computer geeks, that you should keep a minimum of 15-20% of free space on your main hard drive. This is just a rough estimation, but the more free space you have, the faster your Mac works. A computer magazine once performed a test on this, which concluded that the difference in speed can reach as much as 35%. If you work with heavy graphics or video rendering, even more free space is recommended.

How to have more free space? Delete large and old files.

The first way is totally manual and requires you to find them one by one, while for the second way, you just need to make two clicks and CleanMyMac X will do the job for you.

How to clean up Mac with CleanMyMac X:

  1. Download CleanMyMac X (a link to a free edition of the app)
  2. Launch the program.
  3. Go to the Large and Old Files section on the menu.
  4. Click Scan.
  5. Review the details, select what to clean, and then click Clean.

That’s it!

7. Remove old iOS backups

Having your files backed up is a wonderful thing. But over time your Mac becomes overloaded with old backups that take gigabytes of storage on your hard drive. That’s why you should consider removing the old iOS backups you no longer need.

Each backup remains stored on your computer and is accessible via iTunes. To delete the old backups, you need to do the following:

  1. Choose the Apple menu and then select About This Mac.
  2. Go to the Storage tab and click Manage.
  3. Here, choose iOS Files.
  4. Select the backup you want to remove and click Delete.
  5. Confirm and you’re done!

That’s it! The backup files are gone from your Mac forever.

8. Wipe out Language files

Unused language localizations take up about1 GB of storage space. Mac applications come with language files for every language they support. It allows starting using the app in that language immediately. Cool, right? Not always. Just consider: when was the last time you used the app in Bengali or Korean? Since you don’t speak those languages, such files just waste space on your Mac. You need to remove the unnecessary language files and clean MacBook from that clutter.

How to delete the language files? Go to Finder > Applications, then right-click the app which language files you want to remove and choose Show Package Contents. Open the Resources folder and then find folders ending with “.lproj.” Every folder contains language files for one particular language. Note that for every app you should manually find and select the files to remove. But there is an automatic way to delete the language files that will save you tons of time — CleanMyMac X. Just download the application (for free) and it will do the job for you.

9. Delete old DMGs

Disk images (DMGs) often take up valuable space on your Mac. Here’s how to perform a Mac cleanup and get rid of those files:

  1. Open Finder and type “.dmg” in the search bar.
  2. Then delete all files that have .dmg extensions. Don’t forget to remove them from Trash as well.

CleanMyMac X allows you to locate and delete DMGs quicker. With its System Junk module you can remove unused disk image with a single click of a button:

Just press Clean and it’s done!

10. Sort your Downloads folder

Do you also download things and never get rid of them? Then, your Downloads folder probably needs a good old sort out. If you’re too scared to face that enormous pile of files, here’s a quick trick: sort all your downloaded items by date added. Then, scroll till the end of the folder, and you’ll see the dusty files that have been there for a while. Command-click to highlight multiple files and send them to the Trash.

11. Tidy up your desktop

Many people use Desktop as their primary destination for files. But this could be tricky because your OS treats every file on a desktop as an active window. When items on your desktop are too many, Finder gets substantially slower. This leads us to the most compelling advice in this article — cleaning up desktop does miracles!

How To Clean Your Mac Computer For Free

Rather than just leaving every file on your desktop, organize them into folders. The latest macOS does that automatically thanks to the Stacks feature: right-click your Desktop and choose Use Stacks. Now all your files are grouped and you can delete them with a click. You can also use Google Drive, Dropbox, or any external storage device to save your files and keep your desktop tidy.

12. Clean your Mac’s keyboard

Our last but not least advice is to wipe your Mac’s keyboard. As you use your keyboard daily, it quickly gets dirty. Moreover, all those crumbs may live under the keys forever!

If you were wondering how to clean Mac’s keyboard, there are no special rules here. You can try blowing the dust and other particles out of your keyboard once in a while. Disinfecting wipes and alcohol-based sprays may also prove useful. Just choose the piece of fabric and wipe the keys gently to make them clean and shiny!

All in all, be careful with your system files. Don’t delete things you’re not sure about. If you are not completely confident that you can manage the task by yourself, better use a dedicated utility like CleanMyMac X to get a fresh and clean Mac in just two clicks. Here's the video describing quick tips to clean up your Mac:

Happy cleaning!

Just like any day-to-day item, your Mac needs a good cleaning once in a while. Getting rid of all the unnecessary files will help your Mac return to its factory excellence and speed up to match your needs. However, you might find yourself clueless as to where to start your Mac clean up: what can be deleted and what should be left on drive? Don’t worry. You might be a little bit lost right now but, as usual, we have some bulletproof tips and tools to help you clean your Mac and speed it up.

4 steps to Mac cleanup

The good news is that in four (or even less) steps you can get a cleaner Mac and boost your Mac’s performance.

If your Mac is out of storage space or starts running slow, you’re up for a cleaning game. And you don’t have to do it alone. We’ve prepared the smartest memory-boosting hacks and practices to speed of your Mac safely. Time for an easy Mac cleanup!

Disk Cleanup On Mac

Clean up your Mac’s Desktop

This might seem like an obvious step to take, but you’d be surprised how many Mac users believe the Desktop is the perfect place to store files and docs, handy and always on tap. However, that’s a rookie mistake. Fortunately, you can fix it. That’s why you should clean your Mac starting from the Desktop before you go any deeper. Be honest, can you even see your desktop background clearly now or is it obscured because of the icon-riddled mess?

The fact is, that the Finder treats any folder or file on your desktop as a window. A couple of items on the desktop cause no problem, but if the clutter persists, your Finder will soon slow down and get on your nerves. So better sort it all out to separate folders and let us quickly take you to number two.

Free up your Mac’s hard drive

When it comes to storage, there are items you know about (like your photos and videos) and many hidden entities (like cache files, logs, and app junk). These deep-seated junk files may start off small, but over time they will begin to weigh your Mac down.

Tip: According to one test conducted by MacWorld, nearly full hard drives perform 17.5% slower than the cleaner ones. That’s why it’s so important to refresh your hard drive every now and then. Your system will convert the newly-released free space into virtual memory to ensure your apps are running smoothly. Otherwise, if you’re low on space, your Mac will slow down.

One folder you should regularly clean up for a faster Mac is the Downloads folder. This is where junk piles up little by little, resulting in a total mess. For a complete Mac clean up, make sure to also ditch any unnecessary widgets or apps. Wait, but you think you might need them one day? Truth is, if you haven’t used them so far, you won’t use them in the future. So gather all your courage and hit Delete.

If your Mac is still running slow, then it could be due to old hardware. A new SSD or more RAM is the easiest way to boost your hardware performance without having to spend too much.

How do I know what to delete?

What’s really annoying is that some massive folders on your Mac remain invisible. Each app or website visit leaves behind its own archive of data, which keeps growing over time. To hack this, you can use CleanMyMac X app by MacPaw. It uncovers large redundant files you can delete. And this application is notarized by Apple.

  • broken downloads

  • remains of old apps

  • outdated cache

It found 5.81 GB on our computer, but it may detect even more on your Mac.


Take control of startup and login items

When your Mac boots up, the macOS will launch various startup items. Some you do need, but nearly half of them can be safely switched off. Otherwise, they’ll sit in the background using up your system resources and slowing your Mac down.

To remove startup and login items manually, go to System Preferences > Users & Groups and click on your username. Next up, click on “Login Items” and select all the apps you don’t need running at startup. Then click the “-” button below and you’re done. By disabling the startup programs, you’ll have a speedier Mac next time you boot up.

Repair disk permissions

Disk permissions act like doorkeepers preventing third-party apps from meddling with your system. But disk permissions can get broken, which limits your Mac ability to find the right files.

If you’re on El Capitan or older OS X versions, you can repair disk permissions using the following command in the Terminal window:

sudo /usr/libexec/repair_packages --verify --standard-pkgs /

It will now check the validity of your disk permissions. If you get anything saying “permissions differ”, then you can fix it with this command:

sudo /usr/libexec/repair_packages --repair --standard-pkgs -- volume /

If you are a mere mortal, uneasy with using Terminal, a Mac cleaning utility like CleanMyMac X, can do a better, risk-free job. A single click in Maintenance > Repair Disk Permissions solves it without fuss. With your disk permissions fixed and verified you can enjoy a smoother overall Mac experience.

Delete System Junk and browser cache

System Junk can account for significant amount of disk space. It’s a broad term that describes temporary files created by your OS itself and all your apps. Since we mostly use our Macs to go online, the internet-related junk takes up the most space.

Find hidden files on your drive

Such files could be crucial system components and thus protected from accidental deletion. Quite often, however, you’ll encounter remains of old apps, invisible adware, and extensions.

There is a shortcut key combination to reveal the unseen files.

Remove old backups (and Time Machine backups)

There are several layers of backups built in your macOS. Local Time Machine snapshots, iOS, and iCloud backups, etc. If we’re talking about a clean Mac, that’s free from old baggage, you should look into removing them too.

Delete the iCloud backups stored on your Mac

Open System Preferences > iCloud.

Click Manage... at the bottom the pane.

iCloud photos will probably occupy the most space. If you’re ready to say goodbye to them, click Delete.

Build the map of your storage

Any computer is ultimately a tree of folders. What if you could draw the map of all folders you have on your Mac and see how large these folders are?

Apparently, there is an ultra simple way to do it. Some applications like Daisy Disk or CleanMyMac will build such “folder tree” for you and it’s really fascinating to look at.

For example, this is the Space Lens tool from CleanMyMac X:

Download Free Version
The blue bubbles stand represent my folders big and small. You can dive into each folder exploring your drive in a completely new way, much more informative than using the Finder. You can find your long lost folders and locate your biggest space wasters.
