Screen sharing has become a norm for many. People no longer need to send files to their friends and colleagues manually. Instead, they can log on to their computer and share the information in real-time, but it goes far beyond just files and documents.
You can also share games, work on the same projects, and whatever software you’re currently running. As such, it’s crucial to have the feature working at all times in case you need to use it. But we don’t live in a perfect world, and once in a while, you might run into issues trying to share your screen.
If you’re on a Mac and your screen share doesn’t seem to work, you’ve come to the right place. This article will walk you through some quick fixes. Read on to find out more.
Fixing Screen Share Not Working Properly on a Mac
If your screen-sharing apps aren’t working on your Mac, the “Screen Sharing” feature on your Mac probably isn’t enabled. Here’s how to enable the feature:
- On your Mac, go to “System Preferences.”
- Select “Sharing.”
- Ensure that the “Screen Sharing” option is checked.
- If screen share is still not working after adjusting the settings, as shown above, uncheck the “Screen Sharing” feature and recheck it.
The app you’re trying to share your screen through may not have permission to record the screen. Here’s how to grant the app permission to do so:
- Launch “System Preferences.”
- Select “Security & Privacy.”
- Open the “Privacy” tab.
- From the left sidebar, click on “Screen Recording.”
- Press the lock icon in the bottom left corner of the screen to enable changes.
- Check the box next to the app that’s not allowing you to share your screen.
Disable the Remote Management Feature
Macs have a management feature that allows you to control the device using the Apple Remote Desktop app even if you’re not next to your local machine. Unfortunately, you can’t share your screen if this feature is enabled. Here’s how to disable it:
- Navigate to “System Preferences.”
- Click on “Sharing.”
- Uncheck the “Remote Management” feature if it’s checked.
- In the same window, enable “Screen Sharing.”
Switch to an Administrative Account
You need admin privileges to share your screen on a Mac with other users. If you’re logged in as a guest and want to share your screen, switch to the administrator account instead. Here’s how to go about it:
- Click the username in the menu bar.
- Select the administrator account.
- Enter the account password to sign in.
Restart the App
If a specific app doesn’t allow you to share your screen with other users, consider restarting the app. A quick restart can fix various software glitches that might be causing the problem. If that doesn’t resolve the issue, then try restarting your computer.
Discord is more than just a messaging app. You can use it to share games and any other application currently running on your desktop. If the feature isn’t working, here are some quick fixes to help you resolve the issue.
Ensure Discord Has Screen Recording Permissions
To enable screen recording for Discord, follow these steps:
- Launch “System and Preferences.”
- Click on the “Security & Privacy” icon.
- Navigate to the “Privacy” tab and open “Screen Recording.”
- Click the lock icon to enable changes.
- Pick the “Discord” option.
- Quit Discord and restart the app.
Alternatively, you can restart your computer entirely.
Enable the Windowed Mode
Discord doesn’t support screen sharing for applications that are in full-screen mode. Try minimizing the window and see if that helps.
Disable Hardware Acceleration
Screen sharing is a power-hungry and graphic-intense feature that can cause spikes in the CPU load. While the lags and glitches might not be noticeable on newer and speedier Macs, the same can’t be said for older ones. If you’re working on a dated Mac, consider disabling “Hardware Acceleration” to optimize the performance of your computer. Here’s how to do it:
- On your Discord app, open “Settings.”
- Go to “Voice & Video” then “Video Codec.”
- Turn off the toggle switch next to “H.264 Hardware Acceleration.”
Uninstall and Reinstall Discord
If all else fails, you can also try removing the app and installing it afresh. Uninstalling the app and removing all the associated data will remove any corrupted files that might be causing screen share not to work correctly. Here’s a walk-through of the process:
- Go to “Finder” and open the “Applications” window.
- Scroll down to “Discord” and right-click on it.
- Select “Move to Trash.”
- Navigate to “Go,” then “Go to Folder.”
- Type in “/Library/Application Support/” and click “Go.”
- Right-click the “discord” folder and select “Move to Trash.”
- Go back to the “Go to Folder” and type “~/Library/Application Support”.
- If the “Discord” file is still present, delete it.
- Restart your computer.
Disable Screen Capture Using High Technology
Some users have reported that disabling the “screen capture using the latest technology” feature on the Discord app solved their screen sharing issues. Here’s how to disable the feature on your computer:
- Open Discord and press the settings icon.
- Navigate to “Voice & Video” and then “Voice Diagnostics.”
- Turn off the toggle switch next to “Use our latest technology to capture your screen.”
If you can’t share your screen in Microsoft Teams. Follow these steps:

Screen sharing has become a handy feature during Zoom meetings and presentations. If you cannot share your screen during the sessions, the app isn’t allowed to record your computer’s screen.

- Open “System Preferences.”
- Click “Security & Privacy.”
- Launch the “Privacy” tab and choose “Screen Recording.”
- From the available apps, ensure “Zoom” is selected.
Check Camera and Microphone Access
To share your screen with others during Zoom meetings, you must grant Zoom permission to use both the microphone and camera. Here’s how to do it:
- Navigate to “System Preferences.”
- Head to “Security & Privacy.”
- Select “Privacy.”
- Choose “Camera” or “Microphone.”
- Check the box next to “Zoom” or the browser you use to access Zoom.
