How to Clear Cache on Mac (Safari, Chrome, and App Folders)

Mac cache folders are temporary workspaces — browsers stash images and scripts so pages reload faster; apps keep thumbnails, update bits, and other shortcuts. They are useful until they are not: a corrupted cache can make a site stick on an old layout, or a runaway folder can eat gigabytes on a small SSD.

This is a practical guide for current macOS (Sonoma, Sequoia, and neighbors): clear Safari and Chrome the safe way, remove one app’s cache from ~/Library/Caches without nuking the whole Library, and skip the “clean every system folder weekly” advice that causes more trouble than it fixes.

What cache is (and what it is not)

Cache is not your documents, Photos library, or iCloud Drive. Deleting cache should not remove project files. It also is not the same as cookies: cookies keep you signed in; cache keeps page assets. Clear the wrong checkbox in a browser dialog and you will be logging into everything again.

When clearing cache actually helps

• A website shows an outdated page or broken CSS after a redesign.
• One app is bloated or misbehaving and the vendor says “reset cache.”
• Storage is tight and a known cache folder (browser, Adobe, Slack, Docker leftovers) is huge.

If the Mac is merely “feeling slow,” start with Activity Monitor, Login Items, and free disk space — not a ritual wipe of every cache directory.

Browser cache problems show up as “everyone else sees the new site but I do not,” or a login page that loops after a redesign. App cache problems show up as one program spinning forever on launch, or a chat client that will not show new messages until you clear its local store — which is sometimes labeled cache and sometimes labeled data. Read the label.

Clear Safari cache on Mac

To empty Safari’s cache without signing out of sites:

1. Open Safari → Settings → Advanced.
2. Enable Show features for web developers (older macOS: Show Develop menu in menu bar).
3. Choose Develop → Empty Caches, or press Option-Command-E.

To remove cookies and site data for a site (this can sign you out): Safari → Settings → Privacy → Manage Website Data → remove that site or all. Use that when Empty Caches is not enough.

Clear Chrome (and Edge) cache on Mac

1. In Chrome, press Command-Shift-Delete (or Chrome menu → Delete browsing data).
2. Set a time range (All time if you want a full wipe).
3. Check Cached images and files only if you want to stay signed in.
4. Click Delete data.

Microsoft Edge on Mac uses the same idea under its privacy / delete browsing data screen. Leave cookies unchecked unless you intend to sign out.

Firefox users: Settings → Privacy & Security → Cookies and Site Data → Clear Data, then tick Cached Web Content only. Same rule — leave cookies alone unless you want a full sign-out tour.

Clear an app’s cache in ~/Library/Caches

1. Quit the app completely (check the menu bar and Dock).
2. In Finder, choose Go → Go to Folder… and enter ~/Library/Caches.
3. Open the folder for that app (names vary: company ID or app name).
4. Move that app’s cache contents or the app’s cache folder to Trash — do not delete the entire Caches directory.
5. Reopen the app and confirm it still works, then empty Trash if you need the space back.

If a folder refuses with a permissions error, stop. Do not sudo-delete random caches. Use the app’s own “clear cache” setting when it has one.

Some apps (Slack, Spotify, Adobe Creative Cloud, Chromium-based tools) recreate multi-gigabyte caches quickly. That is normal. Clearing them frees space until the app rebuilds what it needs. If a cache returns to many gigabytes overnight, the fix is uninstalling unused apps or changing the app’s offline/download settings — not deleting the folder twice a day.

Storage settings and Safe Mode

Apple’s built-in storage view (Apple menu → System Settings → General → Storage on recent macOS) shows large categories and recommendations. It will not replace targeted cache cleanup, but it shows whether Photos, Messages, or iCloud leftovers are the real space hogs.

Booting into Safe Mode clears some system caches as a side effect and is a reasonable troubleshooting step when the Mac misbehaves after an update — not a weekly chore.

Time Machine local snapshots and large iOS/iPadOS backups under ~/Library/Application Support/MobileSync are frequent “I cleared cache and still have no space” culprits. Those are not cache. Manage them from Storage settings or by deleting old device backups in Finder when a phone is connected.

What not to delete

• Do not recursively delete /System/Library/Caches or the whole of /Library/Caches.
• Do not delete your user Library folder itself.
• Do not use random “cleaner” apps that promise megabyte miracles by stripping caches you need for offline apps or package managers.
• Developer tool caches (npm, Homebrew downloads, Docker, Xcode DerivedData) can be huge — clear those with the tool’s own commands when you understand what you are removing.
