Mac Disk Cleanup: Step-by-Step Tutorial
What Is Disk Cleanup on Mac
Unlike Windows, Mac doesn't have a built-in Disk Cleanup utility. But that doesn't mean you can't do a thorough disk cleanup mac style. macOS gives you several tools and locations to clean, and knowing the right order makes the process efficient and safe.
A proper disk cleanup covers six areas: Trash, Downloads, caches, old apps, large files, and system junk. Working through them in order ensures you don't miss anything and you reclaim the maximum amount of space.
Step 1: Empty the Trash
Start with the easiest win. Right-click the Trash icon in your Dock and select Empty Trash. This permanently deletes everything you have already moved to Trash. It is common to find 1 to 5 GB sitting in Trash that people forgot about.
While you are at it, some apps have their own trash or recently deleted folders. Check Photos for a Recently Deleted album, and Mail for a Trash folder in each email account. These app-level trash cans also hold onto files and take up space on your disk.
Reclaim Mac finds and removes junk files automatically.
Step 2: Clean Downloads and Desktop
Your Downloads folder accumulates files over months and years. Open Finder, go to Downloads, and press Command + 2 to switch to list view. Click the Size column header to sort by file size. Delete any .dmg, .pkg, .zip, or other installer files you no longer need.
Do the same for your Desktop. Many users pile files on the Desktop without thinking. A clean Desktop also helps your Mac perform better since macOS generates preview thumbnails for every file on it. Moving files to organized folders and deleting junk from the Desktop is an essential part of disk cleanup mac users should do regularly.
Step 3: Clear Application Caches
Open Finder, press Command + Shift + G, and type ~/Library/Caches. You will see dozens of folders named after apps and services. Each contains temporary files that can be safely deleted. Select all folder contents, move them to Trash, then empty the Trash.
Common cache folders that grow large include com.apple.Safari, com.spotify.client, com.google.Chrome, and com.apple.bird for iCloud. Some users find 3 to 8 GB in caches alone. These files are rebuilt automatically when needed, so deleting them is safe and a core part of disk cleanup mac maintenance.
Step 4: Remove Unused Applications
Open your Applications folder and review what is installed. Sort by date last opened if possible, or think about which apps you actually use. For each app you want to remove, drag it to Trash. Then go to ~/Library/Application Support and delete the matching folder for that app.
Also check ~/Library/Preferences for files named after the app and ~/Library/Caches. This three-location cleanup ensures a thorough disk cleanup mac users can trust. Each app removal might save anywhere from 50 MB to several gigabytes.
Step 5: Hunt Down Large Files
Open Finder and press Command + F. Set the search criteria to File Size is greater than 500 MB. Review each result carefully. You will often discover old virtual machine files, video recordings, database dumps, or disk images taking up massive amounts of space.
Another approach is using the Storage Management tool built into macOS. Go to About This Mac, Storage, then Manage. The Documents section has a Large Files tab that lists your biggest files sorted by size. This is one of the most effective parts of any disk cleanup mac process.
Step 6: Clear System Logs and Temporary Files
The final step targets system-level cleanup. Open Finder, go to ~/Library/Logs, and delete old log files. Also check /Library/Logs for system-wide logs. These text files are small individually but can accumulate to hundreds of megabytes.
Restart your Mac after completing all steps. Restarting clears temporary files in /tmp and /private/var, flushes memory, and lets the system rebuild only the caches it actually needs. A restart after disk cleanup mac helps your system settle into a clean state.
