If your Mac’s Trash will not empty, first identify whether one item or the whole Trash is stuck. Try deleting a single item from the Trash, check whether it is locked, and restart your Mac before moving on to Safe Mode or disk repair. Emptying Trash permanently deletes its contents, so recover anything you may still need first. Apple’s Finder instructions describe the supported delete and unlock controls.

Start with the error and the affected item

Open Trash from the Dock and try to empty it using the Finder menu: choose Finder > Empty Trash. Read any alert carefully. If Finder names a file or says it is in use, close the app that may have it open, then try again. If the alert points to one item, Control-click that item and choose Delete Immediately. This permanently deletes that item, so proceed only if you are sure you do not need it. Apple documents both the individual-item option and emptying the entire Trash. Delete files and folders on Mac

If Finder reports that the item is locked, select it in Trash and choose File > Get Info (or press Command-I). If the Locked checkbox is selected, deselect it and try again. Changing a lock may require administrator credentials. A locked document can also be deleted when you empty Trash; the lock is a warning against changes, not a guarantee that it will be kept.

Restart Finder and your Mac

If no specific item is identified, relaunch Finder: hold Option, Control-click the Finder icon in the Dock, then choose Relaunch if that menu option appears. Retry emptying Trash. If it remains stuck, save open work and restart the Mac from the Apple menu. Restarting can release a temporary process that was holding a file; this is a troubleshooting step, not a guarantee that it will fix file-system errors.

Check whether the item came from an external drive

Trash can contain items deleted from connected storage as well as from the Mac’s internal disk. If the problem happens only with items from a USB or other external drive, reconnect that drive, make sure it is available in Finder, and retry. Check the cable, connection, and power if the drive is unstable. Apple recommends checking these basics when troubleshooting an external storage device.

If the problem persists on one disk, that points your next troubleshooting step toward that storage device. Avoid unplugging a drive while it is being accessed. If the drive contains important files, make sure you have a current backup before running repairs; Apple recommends a backup before using Disk Utility First Aid.

Try Safe Mode if the problem keeps returning

Safe Mode can help determine whether software that loads at startup is involved. Check your Mac type in Apple menu > About This Mac. For Apple silicon, shut down, press and hold the power button until startup options appear, select a volume, hold Shift, then choose Continue in Safe Mode. For an Intel Mac, restart and immediately hold Shift until the login window appears. Once logged in, try emptying Trash; then restart normally. Safe Mode is a diagnostic step, so if the issue continues, proceed to checking the disk. Start up your Mac in safe mode

Run First Aid when a disk may be involved

Disk Utility’s First Aid checks for certain errors in a storage device’s formatting and directory structure. Open Disk Utility from Applications > Utilities, choose View > Show All Devices if available, and select the affected device. Apple’s procedure starts with the lowest volume in the sidebar and works upward through volumes, containers, and the device, running First Aid on each. If you are checking the startup disk, use macOS Recovery as Apple directs. How to repair a Mac storage device with Disk Utility

First Aid can report errors it cannot repair. Do not erase or reformat a disk as a Trash fix: erasing destroys the disk’s data. If First Aid fails, the drive is missing from Disk Utility, or the problem continues, back up what you can and contact Apple Support or a qualified service provider. Apple notes that an unrepairable or undetected storage device may need further service. How to repair a Mac storage device with Disk Utility

When Trash empties but storage space does not change

Storage figures may not update immediately, and items deleted from iCloud Drive are not included in the Trash amount shown in Mac storage settings. Recheck System Settings > General > Storage after a short wait and confirm which volume’s available space you are viewing. Apple notes that the displayed Trash storage amount excludes items deleted from iCloud Drive. Change Storage settings on Mac

Work through these steps in order: isolate a specific item, check its lock state, restart, test Safe Mode, then use First Aid if the issue appears tied to a disk. Treat alerts and disk errors as clues, and avoid force-delete commands or disk erasure when you are unsure what data they could affect.
