Screen Recording Not Working on Mac: Fix It Step by Step

The most common cause of screen recording failures is a missing permission. macOS requires explicit consent for any app to capture your screen.

Steps: 1. Open System Settings (Apple menu → System Settings). 2. Click Privacy & Security in the sidebar. 3. Scroll down and click Screen Recording. 4. Find the app that is failing (QuickTime Player, Limelight, etc.) in the list. 5. Toggle the switch to ON.

After granting permission, quit and fully relaunch the app — do not just close the window. Many apps require a full restart to pick up new permissions.

If the app does not appear in the Screen Recording list, it may not have requested permission yet. Try launching the app and starting a recording — macOS will prompt you. Click OK and then restart the app.

Starting with macOS Ventura (13), a green dot appears in the menu bar whenever an app is recording your screen. This is a privacy indicator, not an error.

Click the green dot to see which app is actively recording. If you do not recognize the app, you can stop the recording from this menu.

If the green dot appears but your intended recording app is not listed, another app has grabbed the screen recording session. Quit the other app and try again.

The green dot stays lit for the entire recording session. It disappears when you stop recording. This is expected behavior.

1. Quit QuickTime completely (⌘Q, not just closing the window). 2. Go to System Settings → Privacy & Security → Screen Recording and confirm QuickTime Player is toggled on. 3. Relaunch QuickTime. 4. Go to File → New Screen Recording. 5. If you still get an error, try restarting your Mac.

If QuickTime produces a file but it is empty or 0 bytes: this usually means the recording was stopped before it had time to write. Let the recording run for at least 5 seconds before stopping.

QuickTime cannot record other apps' windows that use protected content (DRM). If you are trying to record a Netflix stream or similar, this will intentionally fail — this is a legal restriction, not a bug.

If pressing ⇧⌘5 does nothing, another app may have taken over that keyboard shortcut.

Check for conflicts: Go to System Settings → Keyboard → Keyboard Shortcuts → Screenshots. Make sure "Start/stop screen recording" is checked and not reassigned.

Also check if any third-party app (screenshot tools, window managers) has overridden ⇧⌘5. Look in those apps' settings for screenshot hotkeys.

If the toolbar appears but the Record buttons are greyed out, a screen recording permission is blocking the system tool. This is rare but can happen after macOS updates — restart your Mac to reset the permission cache.

macOS Sequoia (15) introduced additional privacy layers for screen recording. Some third-party apps need to be re-granted permission after upgrading.

After upgrading to Sequoia: go to System Settings → Privacy & Security → Screen Recording and review the full list. Re-toggle any app that is behaving unexpectedly, then restart it.

Sequoia also added a system-level notice when an app starts recording for the first time in a session. Click "Allow" when prompted — the prompt will not appear again for subsequent recordings in the same session.

If a previously working app suddenly fails after a Sequoia update, check for an app update first. Many screen recorders released compatibility patches for Sequoia.

For Limelight specifically: confirm you are running macOS 14 (Sonoma) or later. Limelight does not support macOS 13 or earlier.

Check Limelight appears in System Settings → Privacy & Security → Screen Recording with the toggle enabled. If it is not listed, open Limelight and attempt to start a recording — this will trigger the permission request.

For any third-party screen recorder: ensure the app is up to date, check that Screen Recording permission is granted, and restart the app after granting permission.

If the app crashes when you try to record: delete the app and reinstall from the developer's website or the Mac App Store. Corrupted app bundles occasionally cause crashes specifically on recording start.

A blank .mov file usually means the recording was stopped almost immediately or the file was not written completely.

Ensure your destination drive has enough free space. macOS requires headroom for the temporary recording buffer — a nearly full drive will produce corrupt or empty recordings.

If recordings consistently look washed out or have wrong colors: check that your display color profile is set correctly (System Settings → Displays → Color Profile). "Display P3" is correct for most modern Macs.

For persistent corruption issues, reset the permission database: open Terminal and run "tccutil reset ScreenCapture" — this removes all screen recording permissions and lets you re-grant them fresh. Restart after running this command.
