Screenshots play a major role when it comes to managing everyday tasks. They help record information, share project updates, and keep visual notes. Mac users find the built-in screenshot tool helpful, but when it stops working, even simple tasks get postponed. Minor changes in settings or even software updates usually cause screenshots to disappear or fail to save.
I will walk you through the main reasons why screenshot function stops working on Mac and show you detailed step-by-step methods to fix these issues. By the end, you will discover the best tool to capture screenshots on Mac easily.
Part 1. Why is My Screenshot Not Working on Mac?
If you notice screenshot is not working on Mac, it might be due to a minor technical problem or a change of settings. I have listed the most prevalent causes below:
- Incorrect Keyboard Shortcuts: If you press the wrong keys, then screenshots will not work. For example, pressing “Command + Shift + 3” to capture a whole screenshot or “Command + Shift + 4” to capture a partial section of the screen will not work as intended.
- Changed Screenshot Settings: The Screenshot application in macOS allows users to change their screenshot settings. If “Save to” settings are changed, that screenshot may not end up where you expect it.
- macOS Updates or Compatibility Issues: After installing a new macOS update, some users report that screenshot shortcuts do not respond. This happens due to compatibility issues or incomplete update installations.
- Security or Permission Restrictions: In a few cases, security settings or “Screen Recording” permissions block screenshots, especially when capturing protected content.
As you are now aware of the common reasons, let’s head to the steps to fix these types of issues.

Fix 2. Change the Screenshot Saving Location
Sometimes the screenshot does not work on Mac simply because the files are being saved in a different folder. It may not be a problem at all, just that the save location is different from where you expected. Screenshots are automatically saved on the desktop, although this can be changed in the settings.
Step 1: Press “Command + Shift + 5” to open the Screenshot toolbar and click on “Options.”

Step 2: Under Save to, select the folder where you want your screenshots to be stored (for example, Desktop, Documents, or a custom folder. Try taking a new screenshot, and it should appear in the selected location.

Fix 3. Change Screenshot Settings
When you find the screenshot function not working on Mac, the possibility is that the feature has been turned off in some settings. macOS enables you to enable or disable certain screenshot shortcuts. Unless these are kept in check, your keyboard commands will not work.
Step 1: Click on the Apple icon and choose “System Settings.” Then, select “Keyboard” from the left panel and hit the “Keyboard Shortcuts” button.

Step 2: Again, from the left panel, select “Screenshots” and check that all screenshot options are enabled. If they are unchecked, tick the boxes, press “Done” and try taking a screenshot again.

Fix 4. Restart Mac
The easiest way out is sometimes the best. When your screenshot functionality suddenly stops, it might be because of some minor system glitches. Restarting your Mac removes temporary files, reloads system processes, and generally solves minor problems like this.
For this, click the Apple icon at the top left corner, and choose the “Restart” option. Once your Mac boots back up, try taking a screenshot again.

Fix 5. Enter Safe Mode
Rebooting the Mac usually fixes the problem of screenshot not working, but when that is not true, third-party applications or background services may be disrupting the workings of the system. Therefore, booting in Safe Mode is another reliable way to troubleshoot the screenshot function not working on Mac.
- For Apple Silicon (M1, M2, M3):
Access the Apple menu and click “Shut Down…” on your Mac. Afterwards, press and hold the power button until the startup options window appears. Now, select your startup disk, hold the “Shift” key, then click “Continue in Safe Mode.”

For Intel-based Macs:
Start by Restarting your Mac. Immediately hold the “Shift” key while it boots and release the key once you see the login window. You’ll now see “Safe Boot” in the menu bar.

Fix 6. Update macOS
A common query users ask is, why is my screenshot not working on Mac, especially after a recent update. Frequent updates often address minor errors, boost performance, and enhance security. So, updating your Mac to the latest software version may solve the problem.
Step 1: Click the “Apple” menu in the top-left corner of your screen. Select “System Settings” and choose “General” followed by “Software Update.”

Step 2: Your Mac will check for available updates. If an update is available, click “Update Now” or “Upgrade Now.” Follow the on-screen instructions and allow your Mac to restart once the update completes.
Fix 7. Erase All Content and Settings
If the screenshot does not work on Mac even after restarting, you might need to reset the overall system settings settings.. Here, restoring Mac to its factory setting might help greatly. However, before you proceed, I suggest you backup all the important data because this method will erase all files, apps, and settings.
Step 1: Click the “Apple” and go to “System Settings.” Select General from the left sidebar and scroll down and click “Transfer or Reset.”

Step 2: Proceed with the “Erase All Content and Settings” option and enter administrator password and press the “Unlock” button. Follow the on-screen instructions to complete the process and your Mac will restart after restoring to factory settings.
