When the Trash won't empty on a Mac, Finder almost always says why. An item is in use by an app, it's locked, you don't have permission to change it, it sits on a drive macOS can't write to, or the disk itself has errors. Each cause has its own fix, and none of them needs Terminal.
Start with the quick ones. Quit your open apps and try again. If Finder says an item is locked, hold the Option key while you choose Finder › Empty Trash. If that fails, restart your Mac and empty the Trash before you open anything else.
When those don't work, read the exact message Finder shows, then go to the matching section below. It covers files in use, locked files, permissions, external and network drives, iCloud Drive's deleted items and damaged disks, with the Finder and Disk Utility routes for each.
One warning before anything else: emptying the Trash is permanent. Look through it before you force anything, especially after a large cleanup, because nothing in Finder brings an item back afterwards.
Why the Trash won't empty: read what Finder tells you
Finder's messages are specific. The words in the alert point straight to the cause, so it's worth reading them before trying fixes at random.
What does each Trash message mean?
These are the messages Finder shows in macOS 27, shortened, with what each means and where to start.
| Finder says | What it means | Start here |
|---|---|---|
| The operation can't be completed because the item is in use | An app or background process has the file open | Quit apps, then restart if needed |
| The Trash can't be completely emptied because an item is locked | The item's Locked setting is on | Hold Option while choosing Empty Trash |
| There are some locked items in the Trash | Same as above, asked as a question | Choose Remove All Items or Remove Unlocked Items |
| You don't have permission to access or modify an item | Another user or macOS owns it | Check Sharing & Permissions in Get Info |
| Some items had to be skipped | A mix of locked and permission problems | Get Info on each item |
| Some items cannot be deleted because of System Integrity Protection | The item belongs to macOS | Put it back; don't force it |
| The operation can't be completed because of a disk error | The disk's file system has errors | Run First Aid in Disk Utility |
| Another operation is in progress | Finder is copying, moving or already emptying | Wait for it to finish |
What if Finder shows no message at all?
Some problems are silent. The Trash empties, but the icon still looks full. Folders called Recovered Files keep coming back. Or the Trash is empty and your free space didn't change. Each of those has its own answer in the last sections of this post.
What if the message only gives an error code?
Sometimes Finder says an unexpected error occurred and gives a number instead of a reason. Apple doesn't publish what most of these codes mean. Work through the causes in this post in order: in use, locked, permissions, the drive, then disk errors. One of them is almost always behind it.
What if you can't move something to the Trash at all?
That's a different problem with similar causes. Finder refuses to move an app or document that's open, and says so. It asks before moving a locked item. And it won't move items it isn't allowed to delete, such as apps macOS needs.
Quit the app, unlock the item, or leave macOS's own apps alone. For an app, the post on apps that won't move to the Trash goes through every reason. If Finder says an item's pathname is too long, move its folder somewhere shallower, such as your desktop, and try again from there.
Can you delete everything except the problem item?
Yes, and it's often the quickest way to free most of the space. Open the Trash, select the items you're sure about, Control-click them and choose Delete Immediately, then confirm. The item causing trouble stays behind while you deal with it.
How the Trash works
Knowing where deleted items go explains most of the strange cases. The Trash looks like one place, but it's several.
Where does the Trash keep things?
Items you delete from your startup disk go to a hidden Trash folder in your home folder. Items you delete from an external drive stay on that drive, in a hidden folder of its own with a separate folder for each user. The Trash window in the Dock shows all of them together, as long as the drives are connected.
Each user on the Mac has their own Trash too. You see only yours, and emptying it touches only yours.
What are the ways to empty it?
| Way | What it does | Asks first? |
|---|---|---|
| Empty in the Trash window | Erases everything in the Trash | Yes |
| Finder › Empty Trash or Shift-Command-Delete | The same, from anywhere in Finder | Yes |
| Option-Shift-Command-Delete | The same, without the warning | No |
| Delete Immediately on selected items | Erases only what you selected | Yes |
| Empty Trash in Storage settings | Erases what Storage settings lists as Trash | Yes |
The warning says you can't undo the action, and that's literally true. Finder has no way to bring items back once the Trash is emptied; only a backup can.
Should you turn on automatic emptying?
Remove items from the Trash after 30 days, in Finder › Settings › Advanced, erases each item 30 days after you delete it. Storage settings offers the same thing as Empty Trash automatically. It keeps the Trash from growing for years, at the cost of a deadline for changing your mind.
Items you delete from iCloud Drive are emptied after 30 days anyway, whatever this setting says.
Before you empty: a quick check
Open the Trash, choose View › as List, and add the Date Added column if it isn't there by Control-clicking a column heading. Sort by it, newest first. Anything you don't remember deleting is worth a look, and File › Put Back returns it to where it was.
When an item is in use
"In use" means some process still has the file open. Finder won't erase a file while something is using it, so the fix is to find what that is and close it.
How do you find which app is using a file?
Finder doesn't name the app, so think about where the file came from. A document was probably open in the app that made it. A video may still be open in a player or an editor. An app you moved to the Trash may have left a helper running, often with an icon in the menu bar.
Quit that app with Command-Q, then try again. If you're not sure which app it is, quit all of them. Apps with an icon in the menu bar often keep running after their window closes, so quit those from their menu too.
What if an app won't quit?
Choose Apple menu › Force Quit, or press Option-Command-Esc. Select the app and click Force Quit. Unsaved changes in that app are lost, so save what you can first.
If Finder itself has stopped responding, select Finder in the same window and click Relaunch. Finder is always open, so this is how you restart it.
What if restarting doesn't help?
Restart your Mac, and empty the Trash right after you log in, before opening any apps. Most files that were in use are free again after a restart.
If something that starts with your Mac grabs the file again, start up in safe mode, which keeps login items and extensions that macOS doesn't need from loading:
- Apple silicon: turn your Mac off, then press and hold the power button until you see "Loading startup options". Select your startup disk, hold Shift, and click Continue in Safe Mode.
- Intel: turn on or restart your Mac, then immediately press and hold Shift until you see the login window.
Log in, empty the Trash, then restart normally to leave safe mode. If the file was held by a login item, look in System Settings › General › Login Items & Extensions for anything that belongs to an app you've removed.
When an item is locked
A locked file can't be changed, renamed or erased until it's unlocked. People lock files on purpose to protect them, and some files arrive locked when copied from another computer or a backup.
How do you empty the Trash with locked items?
Hold the Option key while you choose Finder › Empty Trash. Finder's own message for this case says exactly that: the Option key empties everything, locked items included.
You may instead see a question: there are some locked items in the Trash, do you want to remove all of them? Click Remove All Items to erase everything, or Remove Unlocked Items to leave the locked ones for later.
Holding Option also skips the usual confirmation, so look through the Trash first. There's no second chance once it runs.
How do you unlock an item?
- Open the Trash and select the item.
- Choose File › Get Info, or press Command-I.
- In the General section, deselect Locked.
If the checkbox is dimmed, click the lock at the bottom of the Info window and enter an administrator name and password, or use Touch ID. Then empty the Trash as usual.
Why was the file locked in the first place?
The Locked setting is a simple guard against accidental changes, and it travels with the file. Copy a locked file from a backup, a colleague's drive or an old Mac, and it's still locked on yours.
That's also why Finder asks for confirmation when you move a locked item to the Trash. Apple's guide describes it the same way: click Continue to confirm, or unlock the item first.
When you don't have permission
Every file on a Mac has an owner and a set of permissions. When your account isn't allowed to change an item, Finder can't erase it on your behalf.
What does "you don't have permission" mean here?
Usually one of three things. The item belongs to another user on this Mac. It came from another Mac or a drive, and kept its old owner. Or it belongs to macOS or to an app installed for all users, and only an administrator can change it.
How do you fix permissions in Finder?
- Open the Trash, select the item, and choose File › Get Info.
- Open Sharing & Permissions at the bottom of the window.
- Click the lock and enter an administrator name and password.
- Next to your name, choose Read & Write. If your name isn't listed, click the add button and choose yourself.
- For a folder, click the action menu at the bottom and choose Apply to enclosed items.
Close the Info window and empty the Trash. If you'd rather own the item outright, the same action menu has an item that makes you the owner.
If you change your mind before closing the window, choose Revert changes from the same menu.
What about items protected by System Integrity Protection?
If Finder says some items can't be deleted because of System Integrity Protection, those items belong to macOS. System Integrity Protection keeps even administrators from changing them, by design.
Put them back: select them in the Trash and choose File › Put Back. Some guides suggest turning off System Integrity Protection to get rid of them. Don't. It switches off one of macOS's main defenses, and macOS needs those files where they were.
What if the items belong to another user?
Each user on a Mac has their own Trash, and you can't empty someone else's from your account. Ask them to log in and empty it, or, if the account is no longer needed, have an administrator remove it in System Settings › Users & Groups.
Their deleted files still count against your disk, under Other Users & Shared in Storage settings. On a shared Mac, that's one place unexplained space can be.
Items on external drives and network disks
The Trash window shows items from every connected drive, but each drive keeps its own Trash. That's behind most of the puzzles with external drives.
Where do files deleted from an external drive go?
Into a hidden Trash folder on that drive, with a separate folder for each user. While the drive is connected, its items appear in your Trash. Eject it, and they disappear from the Trash window but stay on the drive, still using its space.
To free the drive's space, connect it, open the Trash, and empty it while the drive is still connected. If you deleted files on the drive from another Mac, they're in that Mac user's Trash folder on the drive. They may not show in your Trash; connect the drive to that Mac and empty the Trash there.
Why can't you delete files on some external drives?
Check the drive's format: select it in the Finder sidebar and choose File › Get Info. A drive formatted as NTFS, the usual Windows format, can be read by a Mac but not written to. Finder can't move files on it to the Trash or erase them.
To use it fully with your Mac, copy everything off, then erase it in Disk Utility as APFS, or as ExFAT if a Windows PC needs it too. Erasing removes everything on the drive, so make sure your copy is complete first.
| Drive or format | Can Finder delete files on it? | What to know |
|---|---|---|
| APFS or Mac OS Extended | Yes | Deleted files wait in the drive's own Trash |
| ExFAT or MS-DOS (FAT) | Yes | Works with Windows too; same per-drive Trash |
| NTFS | No | Read-only on a Mac without extra software |
| Time Machine backup disk | Not for other files | It's reserved for backups |
| Network volume | Often without the Trash | Finder may warn the item can't be kept in the Trash |
Why does Finder say an item will be deleted immediately?
Some places can't keep a Trash, such as many network volumes. When you delete from one, Finder warns that the item can't be kept in the Trash and will be deleted immediately. That's permanent: there's no Put Back.
If you see that warning and aren't sure, click Cancel and copy the item somewhere safe first.
What if the drive is a Time Machine backup disk?
Apple says a disk you've set up for Time Machine can be used only for Time Machine backups, not for other files. Finder also refuses to change items inside a backup, with a message that backup items can't be modified.
Leave backups to Time Machine. If you need the space for other files, the answer is a separate drive or a separate APFS volume, not the Trash.
What if the drive acts read-only?
If a drive in a Mac format still won't let you delete files, select it, choose File › Get Info, open Sharing & Permissions, and make sure Ignore ownership on this volume is selected. You may need to click the lock and enter an administrator password first.
If that doesn't help, the drive may have errors. Run First Aid on it, as described in the section on damaged disks below.
iCloud Drive's deleted items
Items you delete from iCloud Drive follow different rules from everything else in the Trash, because they're not only on your Mac.
Why do iCloud Drive items behave differently?
When you move an iCloud Drive item to the Trash, Finder warns that it will be deleted from iCloud Drive and your other devices too. Apple's guide adds two more rules: those items are emptied from the Trash automatically after 30 days, whatever your Finder settings, and Storage settings doesn't count them in its Trash figure.
So a Trash full of iCloud Drive items may not be holding much space on your Mac at all. The files may have been stored only in iCloud to begin with.
How do you remove them for good now?
Empty the Trash on your Mac as usual. You can also remove them from iCloud directly: go to iCloud.com, open iCloud Drive, select Recently Deleted in the sidebar, and choose Delete All, or select files and choose Delete.
Files you permanently remove there can't be recovered. If someone shares a folder with you, remember that deleted shared items move to your Trash and others lose access to them.
What if iCloud Drive items won't leave the Trash?
Deleting iCloud Drive items depends on iCloud syncing, so check you're online and that iCloud Drive isn't showing an error. If Finder shows an error at the top of the iCloud Drive folder about items it can't sync, click Repair; Apple documents this for files with broken permissions.
Then empty the Trash again. If items still linger, they leave by themselves after 30 days.
What about Dropbox, OneDrive and Google Drive?
Their folders work the same way as iCloud Drive. Deleting a file there deletes it from the service and from your other devices, and the copy that lands in your Trash is the last one on this Mac. Each service keeps deleted files on its website for a time; its own help says for how long.
To free space on your Mac without deleting anything, use the app's setting to keep files online only, rather than the Trash.
Can you get an iCloud Drive file back?
Possibly. On iCloud.com, Recently Deleted in iCloud Drive lists files deleted from iCloud Drive in the last 30 days, from any device. If the file is there, select it and choose Recover. If it isn't, it was permanently removed and can't be recovered.
When the disk itself is damaged
If the Trash fails with a disk error, or many items fail at once for no clear reason, the problem may be the disk's file system rather than the files. Disk Utility can check it and repair most errors.
What are the signs of a disk problem?
Finder says an operation can't be completed because of a disk error. Items in the Trash fail one after another, even after a restart. Copying or saving files elsewhere on the same drive fails too, or the drive disconnects by itself.
None of those proves the disk is failing. They do mean it's time to back up and run First Aid.
How do you run First Aid?
Make sure you have a current backup first, in case Disk Utility finds errors it can't fix. Then:
- Open Disk Utility from the Utilities folder in Applications.
- Choose View › Show All Devices.
- Select the last volume listed under the drive, click First Aid, then click Run.
- When it finishes, select the next item up and run First Aid again. Work up through each volume, then the container, then the drive itself.
For your startup disk, Apple recommends running First Aid from macOS Recovery. On a Mac with Apple silicon, turn it off, hold the power button until "Loading startup options" appears, click Options, then Continue, and choose Disk Utility. On an Intel-based Mac, hold Command and R as it starts up.
What if First Aid can't repair it?
If Disk Utility finds errors it can't repair, Apple's advice is to erase the disk, which means copying your files off first. If the drive doesn't appear in Disk Utility at all, check its cable and power for an external drive. For the internal disk, it may need service.
| Situation | Where to run First Aid | Before you start |
|---|---|---|
| External drive | Disk Utility, as usual | Check its cable and power |
| Startup disk, Mac works | macOS Recovery | Make a current backup |
| Mac won't start up all the way | macOS Recovery | Note what you see on screen |
| Errors First Aid can't repair | Erase, after copying files off | Erasing removes everything |
When the Trash empties but something's still wrong
Sometimes the Trash empties without a word, and the problem is what happens afterwards.
Why does the Trash icon still look full?
The Dock's icon can lag behind. Click it: if the window is empty, the Trash is empty, whatever the icon shows.
If the window shows items you thought were gone, they may be on a drive you connected after emptying, or iCloud Drive items still on their way out.
Why do Recovered Files folders keep appearing?
Apple explains that these hold temporary files from apps. An app normally deletes its temporary files when it's done, but if it quits unexpectedly, it can't. When you restart, macOS moves those leftovers into the Trash in a folder called Recovered Files.
Look inside before you empty them. If something in them is useful, drag it out of the Trash first. If they keep coming back after every restart, an app is quitting unexpectedly; check for an update, or ask its developer, as Apple suggests.
Why didn't free space go up after emptying the Trash?
The most common reason is Time Machine's local snapshots, which keep deleted files on the disk for a while so you can restore them. They're removed as they age or when space is needed; the guide to Time Machine's local snapshots explains how to remove them sooner.
Two other reasons: the files were APFS clones that shared their space with copies you kept, or Storage settings hasn't finished recalculating. Our guide to checking storage on a Mac explains which figure to watch.
Why does emptying take so long?
Erasing thousands of small files takes far longer than erasing one large one, because each file is a separate step. A Trash full of old app folders, caches or a code project can take minutes. Let it run; Finder shows its progress, and you can stop it from the progress window if you need to.
What not to do
Many guides to a stubborn Trash end in Terminal. The commands they suggest skip every safeguard Finder has, and some of the advice weakens your Mac's security for good.
Should you use a Terminal command to force-empty the Trash?
No. Commands that delete files act immediately and can't be undone, and a typo in a path can erase far more than the Trash. Everything a stubborn Trash needs can be done in Finder, safe mode, Disk Utility and macOS Recovery.
Be wary of any page that asks you to paste a command to fix the Trash or free space. Fake help pages are a known way to install malware.
What happened to Secure Empty Trash?
Apple removed it in OS X El Capitan. Its security notes say it couldn't guarantee secure deletion on some systems, such as those with flash storage, so the option was removed rather than left in place. There's no replacement in Finder.
| Advice you'll find | Why to skip it | What to do instead |
|---|---|---|
| Delete files with a Terminal command | No undo, no safeguards, easy to mistype | Use Finder, safe mode or First Aid |
| Turn off System Integrity Protection | Removes a core defense; macOS needs those files | Put protected items back |
| Delete the hidden Trash folder itself | Finder and apps expect it to exist | Empty the Trash, or Delete Immediately |
| Install a force-delete utility | Rarely needed; the cause is usually one above | Find the actual cause above |
| Reinstall macOS | Doesn't fix the cause | Restart, safe mode, then First Aid |
When should you stop and get help?
If First Aid finds errors it can't repair, if the internal disk disappears from Disk Utility, or if files fail everywhere, not just in the Trash, stop deleting and back up what you can. Those are signs of a disk that may need service, and further writes can make recovery harder.
How the app does it
Wombit is a native Mac app that shows what's using your storage, explains every item in plain language, and clears it safely: Trash first, undoable and logged. Its catalog describes the Trash itself as Trash, rated Review first: its items may be things you'll want back.
A cleanup in the app never empties the Trash. It moves items there, logs every move, and lets you put them back with Edit › Undo, Put Back or Cleanup History until the Trash is emptied. Finder's own Put Back works on them too.
Emptying the Trash is the only permanent step, and it happens only when you ask. The confirmation says how many items it will erase and how much space they take, that you can't undo it, and how many of the items were moved there by cleanups. It empties only your own Trash.
Measuring the whole Trash and emptying it from the app need Full Disk Access, because macOS doesn't let an app list the Trash otherwise. Moving items to the Trash, Undo and Put Back work without it.
Undo, Put Back, Empty Trash and Cleanup History are free. Cleanup itself is PRO: one payment of $4.99 with lifetime access. Every Pro tool's review is free to open, so you see what would go and why before you buy.
Frequently asked questions
Why won't my Trash empty on my Mac?
Usually an item is still in use by an app, is locked, or belongs to another user or to macOS. Items on an NTFS drive or a damaged disk can also refuse to go. Read the message Finder shows; it names the cause, and each cause has its own fix.
How do I force empty the Trash on a Mac?
Hold the Option key while you choose Finder › Empty Trash; that also removes locked items. If an item is in use, quit your apps or restart, then empty the Trash before opening anything. Safe mode helps when something that starts with your Mac keeps the file open.
How do I delete a file that says it's in use?
Quit the app that last had the file open, including apps that live in the menu bar. If you can't tell which app it is, restart your Mac and empty the Trash before opening anything else. Use Force Quit only for an app that won't quit normally.
What are the Recovered Files folders in my Mac's Trash?
They hold temporary files an app couldn't clean up because it quit unexpectedly. macOS moves them to the Trash when you restart. Check them for anything useful, then empty them; if they come back every time, update the app that keeps quitting.
Does emptying the Trash delete files from iCloud?
Items you moved to the Trash from iCloud Drive are already deleted from iCloud Drive and your other devices. They're emptied automatically after 30 days whatever your settings. On iCloud.com, Recently Deleted in iCloud Drive lists files deleted in the last 30 days that can still be recovered.
Why is my Mac still full after emptying the Trash?
Time Machine's local snapshots can keep deleted files on the disk for a while, and macOS removes them as they age or when space is needed. Files that were APFS clones of copies you kept free little. Storage settings may also need a minute to recalculate.
Can I recover files after emptying the Trash on a Mac?
Not from Finder. If you use Time Machine, open the folder the file was in and open Time Machine to restore it from a backup. Files deleted from iCloud Drive may still be in Recently Deleted on iCloud.com for 30 days.
Where did Secure Empty Trash go?
Apple removed it in OS X El Capitan, because it couldn't guarantee secure deletion on some systems, such as those with flash storage. Finder has no replacement for it.
