Press Shift-Command-4 to capture part of the screen right away, then clear Remember Last Selection, restore your screenshot shortcuts and restart your Mac to bring back a missing selection frame in the Screenshot app.
This guide covers each of those fixes, how to tell whether the app or your user account is at fault, and where lost screenshots go.

How to fix the Screenshot app when capture selected portion stops working
These steps fit this fault: the Shift-Command-5 toolbar still opens and other tools work, but the portion tool shows no frame to drag.
- Press Shift-Command-5 to open Screenshot and display the tools.
- Click Options, then choose Remember Last Selection so that the checkmark disappears.
- Click the Capture a portion of the screen tool.
- Look for the frame on every connected display. If it appears, drag its edges to set the area, then click Capture.
- If no frame appears, press Shift-Command-4, drag the crosshair over the area and release to take the screenshot.
- Restart your Mac from the Apple menu and try the portion tool again.
Apple's screenshot guides don't list a fix for a missing selection frame, so the sections below follow its general checks in order, from the quickest to the most involved.

Why doesn't my screenshot tool work on Mac?
| What you see | Where to look | Fix |
|---|---|---|
| Toolbar opens, but the portion tool shows no frame | A saved selection or a software fault | Clear Remember Last Selection, restart, then test safe mode |
| Shift-Command-5 does nothing | A changed or conflicting shortcut | Open Keyboard Shortcuts > Screenshots and restore defaults |
| The screenshot works, but the file is missing | A different save location or the Clipboard | Check Save to in the Options menu |
| One app's window comes out blocked | That app doesn't allow screenshots | Nothing to repair; Apple TV and DVD Player are examples |
| The fault appears only in your user account | Your account's settings or startup items | Compare with a new user account |
| The fault appears everywhere, even in safe mode | macOS itself | Update macOS, then reinstall it |
How to screenshot again on Mac with keyboard shortcuts
These shortcuts don't need the Screenshot toolbar, so they keep working as a stopgap and also show whether the capture system itself still runs. Add Control to any of them to copy to the Clipboard. You can compare every Mac capture option once this fault is fixed.
| What to capture | Shortcut | Next action |
|---|---|---|
| Entire screen | Shift-Command-3 | Wait for it to save, or click the thumbnail |
| Portion of the screen | Shift-Command-4 | Drag the crosshair and release; press Esc to cancel |
| Move a selection while drawing | Hold Space bar while dragging | The area moves without changing size |
| Window or menu bar | Shift-Command-4, then Space bar | Click the window with the camera pointer; hold Option to leave out the shadow |
| Menu and menu items | Open the menu, then Shift-Command-4 | Drag over the items |
| Screenshot toolbar | Shift-Command-5 | Choose a tool and click Capture |
| Touch Bar | Shift-Command-6 | Saved to the desktop |

Screenshot function not working: restore the Mac keyboard shortcuts
A shortcut stops working when it's turned off or another command already uses the same keys. Restoring defaults resets all your shortcuts, not only the Screenshots ones, so note any custom ones first.
- Choose Apple menu > System Settings.
- Click Keyboard in the sidebar. You may need to scroll down.
- Click Keyboard Shortcuts, then click Screenshots in the sidebar.
- Select the checkbox beside each screenshot shortcut you want turned on.
- Click Restore Defaults in the bottom-left corner if a key combination was changed.
- Press Shift-Command-5 to test.
Why did my screenshot stop working on Mac? Force quit, restart and update macOS
An app that has stopped responding can get in the way, and an out-of-date system can carry a fault that a later version has fixed.
- Press Option-Command-Esc to open the Force Quit window.
- Select any app that isn't responding, then click Force Quit.
- Choose Apple menu > Restart.
- Open System Settings, click General, then click Software Update.
- Install any update listed for your Mac.
- Open the App Store app and update any screen-capture tools you installed there.
- Press Shift-Command-5 and test the portion tool.

Test the Mac Screenshot app in safe mode
Safe mode helps you determine whether a problem comes from software that loads when the Mac starts up. If the frame returns here, a startup item is the likely cause.
Apple silicon Mac
- Choose Apple menu > Shut Down and wait until the Mac is fully off.
- Press and hold the power button until Loading startup options appears.
- Select a volume.
- Hold Shift, then click Continue in Safe Mode.
- Look for Safe Boot in the menu bar, then test Shift-Command-5.
Intel-based Mac
- Turn on or restart the Mac, and immediately hold Shift until the login window appears.
- Log in. You may need to log in a second time.
- Look for Safe Boot in the menu bar, then test Shift-Command-5.
Restart normally to leave safe mode. If the portion tool works in safe mode, remove or update recently added screen-capture, window-management and other utility apps one at a time.
Is the Screenshot app corrupted? Test it in a new Mac user account
A new account has none of your personal settings. If the frame works there, the Screenshot app itself isn't broken, and the cause sits in your own account.
- Choose Apple menu > System Settings, then click Users & Groups in the sidebar.
- Click Add User below the list of users, and enter your password if prompted.
- Choose Standard from the New User pop-up menu.
- Enter a full name and password, then click Create User.
- Press Shift-Command-Q to log out, then log in to the new account.
- Press Shift-Command-5 and test the portion tool.
- Log back in to your own account and delete the test user when you finish.
Can I download the Screenshot app again on Mac?
No separate download exists. Screenshot ships with macOS Mojave 10.14 and later and sits in the Utilities folder inside Applications, so reinstalling macOS is the way to replace it. Apple says a reinstall doesn't remove your apps or personal data, but it still recommends a backup first.
- Back up your Mac.
- Start up from macOS Recovery, using the method for your type of Mac.
- Choose the option to install or reinstall macOS, then click Continue.
- Follow the onscreen instructions.
- Let the installation finish without putting the Mac to sleep or closing its lid.
- Test Shift-Command-5, and contact Apple Support if the frame is still missing.

How to change Screenshot app settings on Mac
Open Shift-Command-5 and click Options. A changed option can look like lost functionality, for example when screenshots save to a folder you no longer check.
| Option | What it controls | Set it to |
|---|---|---|
| Save to | Where files go | A preset location, or Other Location for a folder |
| Timer | The delay before capture | The wait you need, or none |
| Show Floating Thumbnail | The preview in the bottom-right corner | On to mark up or drag the file before it saves |
| Remember Last Selection | Reuse of your last selected area | Off while you troubleshoot |
| Capture Format | HDR or SDR on supported Macs | SDR saves as PNG and is the most compatible; HDR saves as HEIF |
| Show Mouse Pointer | The pointer in the image | Your preference |
