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 the 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.'

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.

4. Choose the Login Items tab.

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

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.

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.

Unused language localizations take up about 1 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.

Useless copies of your documents, files, and photos eat up your Mac's precious space. Therefore, if you wonder how to clean up a Mac and boost its performance, try to delete the duplicates.

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!

Rather than just leaving every file on your desktop, organize them into folders. The latest macOS does that automatically thanks to the Stacks feature. 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.

Erasing your disk: For most reasons to erase, including when reformatting a disk or selling, giving away, or trading in your Mac, you should erase your entire disk.

Erasing a volume on your disk: In other cases, such as when your disk contains multiple volumes (or partitions) and you don't want to erase them all, you can erase specific volumes on the disk.

Erasing a disk or volume permanently deletes all of its files. Before continuing, make sure that you have a backup of any files that you want to keep.

How to erase your disk

1. Start up from macOS Recovery. Then select Disk Utility from the Utilities window and click Continue.
   If you're not erasing the disk your Mac started up from, you don't need to start up from macOS Recovery: just open Disk Utility from the Utilities folder of your Applications folder.
   
2. Choose View > Show All Devices from the menu bar in Disk Utility. The sidebar now shows your disks (devices) and any containers and volumes within them. The disk your Mac started up from is at the top of the list. In this example, Apple SSD is the startup disk:
   
3. Select the disk that you want to erase. Don't see your disk?
4. Click Erase, then complete these items:
   • Name: Type the name that you want the disk to have after you erase it.
   • Format: Choose APFS or Mac OS Extended (Journaled). Disk Utility shows a compatible format by default.
   • Scheme: Choose GUID Partition Map.
5. Click Erase to begin erasing your disk and every container and volume within it. You might be asked to enter your Apple ID. Forgot your Apple ID?
6. When done, quit Disk Utility.
7. If you want your Mac to be able to start up from the disk you erased, reinstall macOS on the disk.

How to erase a volume on your disk

1. Start up from macOS Recovery. Then select Disk Utility from the Utilities window and click Continue.
   If you're not erasing the volume your Mac started up from, you don't need to start up from macOS Recovery: just open Disk Utility from the Utilities folder of your Applications folder.
2. In the sidebar of Disk Utility, select the volume that you want to erase. The volume your Mac started up from is named Macintosh HD, unless you changed its name. Don't see your volume?
3. Click Erase, then complete these items:
   • Name: Type the name that you want the volume to have after you erase it.
   • Format: Choose APFS or Mac OS Extended (Journaled). Disk Utility shows a compatible format by default.
4. If you see an Erase Volume Group button, the volume you selected is part of a volume group. In that case, you should erase the volume group. Otherwise, click Erase to erase just the selected volume. You might be asked to enter your Apple ID. Forgot your Apple ID?
   
5. When done, quit Disk Utility.
6. If you want your Mac to be able to start up from the volume you erased, reinstall macOS on that volume.

Reasons to erase

You can erase at any time, including in circumstances such as these:

• You want to permanently erase all content from your Mac and restore it to factory settings. This is one of the final steps before selling, giving away, or trading in your Mac.
• You're changing the format of a disk, such as from a PC format (FAT, ExFAT, or NTFS) to a Mac format (APFS or Mac OS Extended).
• You received a message that your disk isn't readable by this computer.
• You're trying to resolve a disk issue that Disk Utility can't repair.
• The macOS installer doesn't see your disk or can't install on it. For example, the installer might say that your disk isn't formatted correctly, isn't using a GUID partition scheme, contains a newer version of the operating system, or can't be used to start up your computer.
• The macOS installer says that you may not install to this volume because it is part of an Apple RAID.

About APFS and Mac OS Extended

Disk Utility in macOS High Sierra or later can erase using either the newer APFS (Apple File System) format or the older Mac OS Extended format, and it automatically chooses a compatible format for you.

How to choose between APFS and Mac OS Extended

Disk Utility tries to detect the type of storage and show the appropriate format in the Format menu. If it can't, it chooses Mac OS Extended, which works with all versions of macOS. If you want to change the format, answer these questions:

• Are you formatting the disk that came built into your Mac?
  If the built-in disk came APFS-formatted, Disk Utility suggests APFS. Don't change it to Mac OS Extended.
• Are you about to install macOS High Sierra or later for the first time on the disk?
  If you need to erase your disk before installing High Sierra or later for the first time on that disk, choose Mac OS Extended (Journaled). During installation, the macOS installer decides whether to automatically convert to APFS—without erasing your files.
• Are you preparing a Time Machine backup disk or bootable installer?
  Choose Mac OS Extended (Journaled) for any disk that you plan to use as a Time Machine backup disk or as a bootable installer.
• Will you be using the disk with another Mac?
  If the other Mac isn't using macOS High Sierra or later, choose Mac OS Extended (Journaled). Earlier versions of macOS don't work with APFS-formatted volumes.

How to identify the format currently in use

If you want to know which format is currently in use, use any of these methods:

• Select the volume in the Disk Utility sidebar, then check the information shown on the right. For more detail, choose File > Get Info from the Disk Utility menu bar.
• Open System Information and select Storage in the sidebar. The File System column on the right shows the format of each volume.
• Select the volume in the Finder, then choose File > Get Info from the menu bar. The Get Info window shows the Format of that volume.

If your disk or volume doesn't appear, or the erase fails

1. Shut down your Mac, then unplug all nonessential devices from your Mac.
2. If you're erasing an external drive, make sure that it's connected directly to your Mac using a cable that you know is good. Then turn the drive off and back on.
3. If your disk or volume still doesn't appear in Disk Utility, or Disk Utility reports that the erase process failed, your disk or Mac might need service. If you need help, please contact Apple Support.

• If you can't start up from macOS Recovery, you can use a different startup disk instead.
• If Disk Utility shows a Security Options button in the Erase window, you can click that button to choose between a faster (but less secure) erase and a slower (but more secure) erase.
