Can You Delete ~/Library/Caches on Mac? Safe Cleanup Steps
Yes, You Can Safely Delete Files Inside ~/Library/Caches
Everyday Mac users frequently uncover tens of gigabytes trapped inside a hidden folder called ~/Library/Caches and hesitate, worried that emptying it will break macOS, erase family photos, or delete login passwords.
Here is the definitive reassurance from our engineering team: It is completely safe to delete the contents of ~/Library/Caches, provided the associated apps are closed. Your Mac will not crash, your personal documents remain untouched, and closed applications will automatically rebuild fresh, lightweight cache files as needed.
What Is ~/Library/Caches and Why Does It Exist?
To understand why your Mac accumulates gigabytes of cache data, it helps to understand the difference between active memory and permanent storage.
Your physical desk where your current open projects, browser tabs, and documents stay spread out so you can reach them in a split second without getting up.
Your massive storage cabinet where macOS and applications archive permanent files, documents, and temporary helper scratchpads for later retrieval.
Your ~/Library/Caches folder is essentially a digital scratchpad located on your SSD. When you stream music on Spotify, scroll through high-resolution channels on Discord, or edit photos, apps download artwork, sound clips, and web scripts. Instead of re-downloading those identical assets over your internet connection five minutes later, apps save a copy inside ~/Library/Caches.
The Three Different Cache Locations on macOS
There are three separate cache folders on modern Macs. Knowing which one you are viewing is crucial for safety:
- User Caches (
~/Library/Caches): Located in your personal user home folder. Safe to clear. This is where 95% of disk bloat lives. - System Caches (
/Library/Caches): Located at the root of the hard drive for shared computer resources. Rarely exceeds 2GB. Leave alone unless troubleshooting system daemons. - Core OS Caches (
/System/Library/Caches): Sealed on Apple's read-only Signed System Volume. macOS protects this area behind digital security glass. You cannot delete this, and you never need to.
Is It Safe to Delete? Apple's Two-Vault Security Architecture
The biggest fear Mac owners experience when browsing through Finder is: "What if I delete something essential and my Mac refuses to boot?"
Modern macOS uses Apple's robust Two-Vault System:
| Vault Section | What It Contains | System Protection Level | Safe to Clean? |
|---|---|---|---|
| System Vault (SSV) | macOS kernel, system drivers, default applications | Cryptographically Sealed | Protected by Apple |
| Data Vault (Your Home) | Personal files, user preferences, temporary caches | User Permissions | 100% Safe to Clean |
Since macOS Big Sur through modern macOS releases, Apple stores the entire core operating system on a dedicated, cryptographically sealed volume called the Signed System Volume (SSV). Even with administrator privileges, third-party software and user actions cannot modify or damage the core operating system files.
Your ~/Library/Caches folder sits entirely inside your personal Data Vault. Deleting items here cannot stop your Mac from starting up, cannot delete system frameworks, and cannot harm your computer.
What Actually Happens When You Delete ~/Library/Caches?
When you clear user caches, here is the exact sequence of events that occurs on your Mac:
When you reopen Spotify or Chrome, the app notices its temporary cache is missing. It takes 1 to 2 extra seconds to pull fresh thumbnails or web icons, then returns to full speed.
If an app was crashing or displaying blank windows due to a damaged cache file, clearing the folder forces the app to write a clean, uncorrupted copy.
All deleted cache blocks immediately transition to free space on your APFS drive, relieving startup disk full warnings and freeing room for macOS updates.
Your login credentials, account passwords, and preferences remain perfectly intact because they are stored in macOS Keychain and Application Support, not Caches.
The Biggest Offenders: Why ~/Library/Caches Balloons in Size
In everyday testing by our team, we regularly encounter Macs where ~/Library/Caches consumes 40GB to 80GB of storage. If macOS and apps were designed to clean up after themselves, this folder would rarely exceed 5GB.
The culprit is usually one of these common apps that fail to set reasonable cache limits:
- Spotify (
~/Library/Caches/com.spotify.client): Often balloons to 15GB to 30GB. Spotify caches virtually every streamed song snippet locally, even if you never listen to that album again. - Slack and Discord (
com.tinyspeck.slackmacgap/com.hnc.Discord): These Electron-based tools retain gigabytes of shared images, animated emojis, and embedded videos from months ago. - Google Chrome and Arc (
com.google.Chrome): Stores hundreds of thousands of microscopic web page fragments and cached banner assets that quickly aggregate into 10GB+. - Adobe Creative Cloud: Leaves massive scratch buffers and temporary font previews even after you finish client projects.
- Uninstalled Applications: When you drag old software to the Trash, macOS leaves behind its old cache folder in
~/Library/Cachesforever. Learn more in our guide on why dragging apps to Trash leaves leftover files.
How to Clean ~/Library/Caches Safely: Two Approaches
Method 1: The Manual Finder Method (Free, No Software Required)
You do not need to install anything to inspect and clean your user cache. Follow these exact steps to do it safely:
- Quit your running applications: Press Command + Q on any open browser, music player, or creative software so they are not actively writing to their cache files.
- Open Finder: Click anywhere on your desktop to activate Finder.
- Open Go to Folder: Press Command + Shift + G (or click Go → Go to Folder… in the menu bar).
- Enter the exact path: Type
~/Library/Cachesand press Return. - Inspect the subfolders: You will see folders named after applications, such as
com.spotify.clientorGoogle. - Delete files inside, not the parent folder: Select the contents of the bloated app cache folder, right-click, and select Move to Trash.
- Empty your Trash: Files in the Trash still take up space on your Mac. Empty the Trash to reclaim the gigabytes.
# Check the total size of your User Caches without deleting anything
du -sh ~/Library/Caches 2>/dev/null

du -sh ~/Library/Caches/* 2>/dev/null | sort -hr | head -n 10
Note: The commands above are completely read-only. They simply measure your cache size and will never delete any files.
Method 2: Automated Safe Cleaning with DiskCompanion
While manual cleaning works, combing through hundreds of cryptic folder names like com.apple.nsurlsessiond or com.adobe.acc.AdobeDesktopService can be intimidating and tedious. If you delete an active app's temporary lock file while it is running, the app may freeze.
This is why we built DiskCompanion's safe cache cleaner. Instead of requiring you to hunt through hidden system folders:
- Interactive Disk Explorer: Visually inspect your drive with an interactive visual map (Disk Explorer) that shows exactly which apps are hoarding space.
- Smart Safety Rules: Automatically excludes active running processes, ensuring only safe, closed application caches and orphaned leftovers are targeted.
- Native Trash Reversibility: DiskCompanion never runs dangerous permanent wipe commands. Every cleaned file moves directly to your native Mac Trash with full "Put Back" support.
- Zero Background Daemons: Unlike legacy utilities that install persistent background helpers eating 500MB of RAM, DiskCompanion runs only when you open it and uses zero battery when closed.

Mac Library Caches FAQ
Clear answers on what ~/Library/Caches does, whether it is safe to delete, and what happens to your apps.
Is it safe to delete the ~/Library/Caches folder on Mac?
You should not delete the ~/Library/Caches folder itself, but you can safely delete the files and folders inside it. When you delete the contents of user cache folders for apps that are currently closed, macOS and your applications simply regenerate fresh cache files the next time they launch.
Will deleting ~/Library/Caches delete my personal files or passwords?
No. Your documents, photos, and desktop files live in separate user directories. Passwords and credentials reside securely inside macOS Keychain, and application settings live in ~/Library/Preferences and Application Support. Caches strictly hold temporary scratch data such as web page previews, streaming buffers, and downloaded thumbnails.
What is the difference between /Library/Caches and ~/Library/Caches?
The tilde symbol represents your personal user home directory. ~/Library/Caches holds temporary files generated by apps you personally run, such as Spotify, Slack, and Chrome. In contrast, /Library/Caches (without the tilde) contains system-wide caches shared across all user accounts on the Mac.
Why does my ~/Library/Caches folder take up 50GB or more?
Many modern apps do not manage their storage footprints responsibly. Streaming apps (Spotify, YouTube), communication tools (Slack, Discord, Teams), and creative tools (Adobe Creative Cloud, Xcode) continuously write audio chunks, image previews, and compiled assets to your disk without automatic limits or expiration routines.
How often should I clear ~/Library/Caches on my Mac?
You do not need to clear your cache daily or weekly. Clearing caches is recommended when your Mac warns you of low startup disk space, when an application crashes repeatedly due to corrupted cache files, or during a seasonal storage cleanup to reclaim 20GB to 60GB of wasted SSD storage.
