If you’re willing to dig into your iMac’s data a little, there’s no reason to buy additional software to help you clean up your hard drive. All you really need is the willpower to announce, “I simply don’t need this particular item any longer.” (Sometimes, that’s tougher than it may seem.)
Consider all the stuff that you probably don’t really need:
Game demos and shareware that you no longer play (or even remember)
Movie trailers and other QuickTime video files that have long since passed into obscurity
Temporary files that you created and promptly forgot
Log files that chronicle application installations and errors
GarageBand loops and iMovie video clips you’ll never use
StuffIt and Zip archives that you downloaded and no longer covet
iTunes music, video, and movies that no longer appeal
How hard is it to clean this stuff off your drive? Easier than you might think!
You can quickly delete files.
You can remove items from your iTunes Library (especially movies, which take up several gigabytes of space each). If you’ve purchased an item from the iTunes Store, don’t forget that you can download that item again in the future for free — perhaps when you’ve added an external drive to hold some of your stuff.
You can move seldom-used files and folders to external storage (such as a USB flash drive, an external hard drive, or a DVD).
You can uninstall applications purchased from the App Store using Launchpad. From the Launchpad display, click and hold down the icon until it wiggles. If an X button appears on the icon, you can click the X to remove the application from your iMac. Again, these applications can be reinstalled at any time.
You can get rid of most of the space taken by any application (often the whole application) by deleting its application folder that was created during the installation process.
Always check the application’s README file and documentation for any special instructions before you manually delete any application’s folder! If you created any documents in that folder that you want to keep, don’t forget to move them before you trash the folder and its contents. In fact, some applications may come with their own uninstall utility, so checking the README file and documentation may save you unnecessary steps.
Removing an application or file from your hard drive usually takes two simple steps:
If you’re willing to dig into your iMac’s data a little, there’s no reason to buy additional software to help you clean up your hard drive. All you really need is the willpower to announce, “I simply don’t need this particular item any longer.” (Sometimes, that’s tougher than it.
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: Open Finder and type “disk image” in the search bar. If you’re willing to dig into your iMac’s data a little, there’s no reason to buy additional software to help you clean up your hard drive. All you really need is the willpower to announce, “I simply don’t need this particular item any longer.” (Sometimes, that’s tougher than it may seem.) Unnecessary files and unneeded. Repair a storage device in Disk Utility on Mac. Disk Utility can fix certain disk problems—for example, multiple apps quit unexpectedly, a file is corrupted, an external device doesn’t work properly, or your computer won’t start up. Disk Utility can’t detect or repair all problems that a disk may have.
Display the file or application folder in a Finder window.
Delete the file or folder with one of these steps:
Drag the icon to the Trash.
Select the icon and press ⌘+Delete.
Right-click the icon and choose Move to Trash from the contextual menu.
Select the icon and click the Delete button on the Finder toolbar (if you added one).
Truly, no big whoop.
Unlike programs in the Windows world, most OS X applications don’t need a separate, silly uninstall program (although some larger Mac applications include one for convenience).
Don’t forget to actually empty the Trash, or you’ll wonder why you aren’t regaining any hard drive space. (El Capitan works hard to store the contents of the Trash until you manually delete it, just in case you want to undelete something.) To get rid of that stuff permanently and reclaim the space, do the following:
Click the Trash icon on the Dock and hold down the button — or right-click — until the pop-up menu appears.
Choose Empty Trash.
Associated files in other folders
Some applications install files in different locations across your hard drive. (Applications in this category include the Microsoft Office suite and Adobe Creative Suite and Creative Cloud applications like Adobe Photoshop.) How can you clear out these orphan files after you delete the application folder?
The process is a little more involved than deleting a single folder, but it’s still no big whoop. Here’s the procedure:
Click the Search text box in a Finder window.
Type the name of the application in the Search text box. If you want to remove Toast Titanium, you search for every file with the word Toast in its name; therefore, you find both the application and its main folder. This trick displays files created in other folders that include your search word in their names, such as project files, PDF files, and the font files that appear in the system Fonts folder.
Optimized Storage in macOS Sierra and later* can save space by storing your content in iCloud and making it available on demand. When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically. Each file stays right where you last saved it, and downloads when you open it. Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.
* If you haven't yet upgraded to macOS Sierra or later, learn about other ways to free up storage space.
Find out how much storage is available on your Mac
Mac Disk Cleanup Utility
Choose Apple menu > About This Mac, then click Storage. Each segment of the bar is an estimate of the storage space used by a category of files. Move your pointer over each segment for more detail.
Click the Manage button to open the Storage Management window, pictured below. This button is available only in macOS Sierra or later.
Manage storage on your Mac
The Storage Management window offers recommendations for optimizing your storage. If some recommendations are already turned on, you will see fewer recommendations.
Store in iCloud
Clean Disk Mac 10.15
Click the Store in iCloud button, then choose from these options:
Desktop and Documents. Store all files from these two locations in iCloud Drive. When storage space is needed, only the files you recently opened are kept on your Mac, so that you can easily work offline. Files stored only in iCloud show a download icon , which you can double-click to download the original file. Learn more about this feature.
Photos. Store all original, full-resolution photos and videos in iCloud Photos. When storage space is needed, only space-saving (optimized) versions of photos are kept on your Mac. To download the original photo or video, just open it.
Messages. Store all messages and attachments in iCloud. When storage space is needed, only the messages and attachments you recently opened are kept on your Mac. Learn more about Messages in iCloud.
Storing files in iCloud uses the storage space in your iCloud storage plan. If you reach or exceed your iCloud storage limit, you can either buy more iCloud storage or make more iCloud storage available. iCloud storage starts at 50GB for $0.99 (USD) a month, and you can purchase additional storage directly from your Apple device. Learn more about prices in your region.
Optimize Storage
Disk Cleaner Mac
Click the Optimize button, then choose from these options.
Automatically remove watched movies and TV shows. When storage space is needed, movies or TV shows that you purchased from the iTunes Store and already watched are removed from your Mac. Click the download icon next to a movie or TV show to download it again.
Download only recent attachments. Mail automatically downloads only the attachments that you recently received. You can manually download any attachments at any time by opening the email or attachment, or saving the attachment to your Mac.
Don't automatically download attachments. Mail downloads an attachment only when you open the email or attachment, or save the attachment to your Mac.
Optimizing storage for movies, TV shows, and email attachments doesn't require iCloud storage space.
Empty Trash Automatically
Empty Trash Automatically permanently deletes files that have been in the Trash for more than 30 days. Vpn for opera mac.
Reduce Clutter
Reduce Clutter helps you to identify large files and files you might no longer need. Click the Review Files button, then choose any of the file categories in the sidebar, such as Applications, Documents, Music Creation, or Trash.
You can delete the files in some categories directly from this window. Other categories show the total storage space used by the files in each app. You can then open the app and decide whether to delete files from within it.

Other ways that macOS helps automatically save space
With macOS Sierra or later, your Mac automatically takes these additional steps to save storage space:
Detects duplicate downloads in Safari, keeping only the most recent version of the download
Reminds you to delete used app installers
Removes old fonts, languages, and dictionaries that aren't being used
Clears caches, logs, and other unnecessary data when storage space is needed
How to free up storage space manually
Even without using the Optimized Storage features of Sierra or later, you can take other steps to make more storage space available:
Music, movies, and other media can use a lot of storage space. Learn how to delete music, movies, and TV shows from your device.
Delete other files that you no longer need by moving them to the Trash, then emptying the Trash. The Downloads folder is good place to look for files that you might no longer need.
Move files to an external storage device.
Compress files.
Delete unneeded email: In the Mail app, choose Mailbox > Erase Junk Mail. If you no longer need the email in your Trash mailbox, choose Mailbox > Erase Deleted Items.

The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps might show storage categories such as Not Mounted, VM, Recovery, Other Volumes, Free, or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file frees up only the space required by any data you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.
