By Techevangelist · Updated August 28, 2026

Quick Fixes (Try First)

1. Restart your Mac - Fixes temporary glitches
2. Check storage - Go to Apple Menu > About This Mac > Storage. Screenshots need free space.
3. Try a different shortcut - Cmd+Shift+3 (full screen) or Cmd+Shift+4 (selection)

Fix 1: Reset Screenshot Keyboard Shortcuts

macOS Sonoma and Sequoia sometimes reset shortcuts after updates:

1. Open System Settings
2. Click Keyboard (left sidebar)
3. Click Keyboard Shortcuts
4. Click Screenshots (left sidebar)
5. Verify shortcuts are set:
   • Capture entire screen: Cmd+Shift+3
   • Capture selected area: Cmd+Shift+4
   • Capture window: Cmd+Shift+4+Space
   • Screen Recording: Cmd+Shift+5
6. If changed, click Restore Defaults

Fix 2: Check Screen Recording Permissions

1. Open System Settings
2. Click Privacy & Security
3. Click Screen Recording
4. Ensure Terminal and Screenshot apps are toggled ON
5. If changed, restart your Mac

Fix 3: Reset NVRAM

NVRAM stores display and screenshot settings. Resetting often fixes the issue:

1. Shut down your Mac
2. Turn it on and immediately press and hold Option+Command+P+R
3. Hold for 20 seconds
4. Release and let your Mac restart normally

Note: This works on Intel Macs only. Apple Silicon Macs reset NVRAM automatically.

Fix 4: Check Storage Space

1. Click the Apple Menu (top left)
2. Click About This Mac
3. Click Storage
4. Ensure you have at least 1GB free
5. If full, delete unnecessary files or move them to iCloud

Fix 5: Update macOS

1. Open System Settings
2. Click General
3. Click Software Update
4. Install any available updates
5. Restart your Mac after updating

Fix 6: Check Screenshot Save Location

1. Press Cmd+Shift+5 to open Screenshot app
2. Click Options
3. Check Save to location
4. Ensure it's set to a valid folder (Desktop, Documents, etc.)
5. If the folder doesn't exist, screenshots fail silently

Fix 7: Safe Mode Test

1. Shut down your Mac
2. Turn it on and hold Shift (Intel) or hold power button and select Safe Mode (Apple Silicon)
3. Try taking a screenshot in Safe Mode
4. If it works, restart normally - a third-party app was causing the issue

Fix 8: Use Screenshot App Instead

If keyboard shortcuts still don't work:

1. Open Spotlight (Cmd+Space)
2. Type Screenshot and press Enter
3. Use the on-screen controls to capture
