How to Fix OnVUE on Your Mac
A complete troubleshooting guide to resolve camera, screen sharing, browser, and compatibility issues with Pearson VUE OnVUE on macOS.
Last updated
Quick answer
OnVUE fails on a Mac most often because your browser lacks Camera, Microphone, or Screen Recording permission. Open System Settings, Privacy and Security, and enable all three for Chrome or Firefox, update the browser, then turn off any VPN and firewall before launching. Need a newer Mac?

To fix OnVUE on a Mac, grant your browser Camera, Microphone, and Screen Recording permission in System Settings, update to a supported browser, then turn off the firewall, antivirus, and any VPN before you launch the test. OnVUE is the platform that delivers your Pearson VUE exam, and when the camera will not connect, screen sharing keeps failing, the browser crashes on launch, or the system check reports an error, you are not alone. These macOS compatibility problems are common and well-documented.
The good news is that virtually all OnVUE issues on Mac can be fixed. The platform has specific system requirements and permissions that must be met, and macOS security features, while excellent for protecting your privacy, can sometimes block OnVUE from reaching your camera, microphone, and screen. In this guide, we walk through every known issue and its solution, step by step.
This guide works the same whether you are taking a professional certification exam from a home office in Dubai, a university in Abu Dhabi, or a co-working space in Sharjah. It gets OnVUE running smoothly so you can focus on the exam itself. Let's troubleshoot.

Grant Camera and Microphone Permissions
The most common reason OnVUE fails on Mac is that camera and microphone permissions have not been granted. macOS requires explicit user consent before any application can access these hardware components, and if you accidentally clicked Deny when prompted, OnVUE will not be able to conduct the pre-exam check or monitor you during the test.
To fix this, open System Settings > Privacy & Security > Camera. Scroll through the list of applications and make sure your browser (Google Chrome, Mozilla Firefox, or Safari) has the camera toggle switched on. Do the same for Microphone in the same Privacy & Security section. If you are using Chrome, also check chrome://settings/content/camera and chrome://settings/content/microphone in the browser to ensure the permissions are granted there as well.
If the browser is listed but the toggle is disabled, enable it. If the browser does not appear in the list at all, try launching OnVUE again. macOS should then prompt you with a permission request. Make sure to click Allow, not Deny. If you are still having trouble, try removing and re-adding the browser's permission: turn the toggle off, quit the browser completely, reopen it, and turn the toggle back on.
- System Settings > Privacy & Security > Camera, enable your browser
- System Settings > Privacy & Security > Microphone, enable your browser
- In Chrome: check chrome://settings/content/camera and /microphone
- In Firefox: check Settings > Privacy & Security > Permissions > Camera
- Always click Allow when macOS prompts for camera or mic access
- Quit and reopen the browser after changing permission settings
Fix Screen Recording and Screen Sharing Permissions
OnVUE requires screen recording permission to monitor your screen during the exam. This is a critical requirement. Without it, the exam cannot proceed. On macOS Catalina and later, screen recording is a separate permission that must be explicitly granted, and it is located in a different section of System Settings than regular screen sharing.
Go to System Settings > Privacy & Security > Screen Recording. Find your browser in the list and ensure the toggle is turned on. This is different from the Screensharing permission, OnVUE specifically needs Screen Recording, not just Screensharing. If your browser is not listed, open OnVUE, and macOS should prompt you to grant the permission. Click Open System Settings if prompted, and enable the toggle.
After enabling Screen Recording, you must fully quit and restart your browser for the change to take effect. Simply closing the browser window is not enough, use Command + Q to quit the application completely, then reopen it. Some users report that they need to restart their Mac entirely after granting Screen Recording permission for OnVUE to detect it. If the OnVUE system check still fails after enabling the permission, restart your Mac and try again.
- System Settings > Privacy & Security > Screen Recording, enable browser
- This is different from Screensharing because OnVUE needs Screen Recording specifically
- Fully quit the browser with Command + Q after granting permission
- Restart your Mac if OnVUE still does not detect the permission
- Ensure no other screen recording apps (OBS, Zoom) are running simultaneously
- Disable any display management apps that might interfere
Resolve Browser Compatibility Issues
OnVUE works best with specific browser versions, and using an unsupported or outdated browser is a frequent cause of problems. Pearson VUE officially supports the latest versions of Google Chrome, Mozilla Firefox, Safari, and Microsoft Edge on macOS. Using a lesser-known browser like Brave, Opera, or Vivaldi is not recommended and may cause the system check to fail.
Start by checking your browser version. In Chrome, go to chrome://settings/help. In Firefox, go to Settings > General. In Safari, go to Safari > About Safari. Compare your version with the latest available, if you are more than one major version behind, update your browser before attempting the exam. Also ensure that you do not have any aggressive ad blockers, privacy extensions, or VPN extensions that could interfere with OnVUE's functionality.
If OnVUE launches but crashes immediately or shows a blank screen, try clearing your browser cache and cookies, then relaunching. In Chrome, go to chrome://settings/clearBrowserData and select All time. If the problem persists, try a different supported browser. Sometimes a simple browser switch from Chrome to Firefox (or vice versa) resolves unexplained issues. Pearson VUE also recommends disabling hardware acceleration in Chrome (chrome://settings > System > Use hardware acceleration when available) if you experience display or rendering problems during the exam.
- Use a supported browser: Chrome, Firefox, Safari, or Edge (latest versions)
- Check and update your browser to the newest version before the exam
- Disable ad blockers, VPN extensions, and privacy plugins before launching OnVUE
- Clear browser cache and cookies if OnVUE crashes or shows a blank screen
- Disable hardware acceleration in Chrome if you see display issues
- Try a different supported browser if problems persist
Configure macOS Security Settings and Firewall
macOS includes built-in security features that can block OnVUE from functioning correctly. The Firewall, Gatekeeper, and malware protection systems are designed to keep your Mac safe, but they can sometimes interfere with legitimate applications like OnVUE that need to access hardware and network resources in unusual ways.
Check your Firewall settings by going to System Settings > Network > Firewall. If the Firewall is turned on, it may be blocking OnVUE's connection to Pearson VUE's servers. Try temporarily turning the Firewall off before launching OnVUE, remember to turn it back on after your exam. If you prefer to keep the Firewall active, you can add an exception for your browser in the Firewall options.
Gatekeeper is another potential issue. If macOS is blocking OnVUE's system extension or helper application from running, you may see a message saying the software cannot be opened because it is from an unidentified developer. To fix this, go to System Settings > Privacy & Security and scroll down. You should see a message about blocked software with an Allow Anyway button. Click it, and you may need to enter your Mac login password. Also check that your Mac is not running in a restricted user account that limits application installation or system access.
- Temporarily disable the Firewall in System Settings > Network > Firewall
- Add a Firewall exception for your browser if you prefer to keep it enabled
- Check for blocked software warnings in Privacy & Security settings
- Click Allow Anyway for any OnVUE-related blocked applications
- Ensure you are using an administrator account, not a restricted user account
- Re-enable the Firewall after completing your exam
Resolve Antivirus and Third-Party Software Conflicts
Third-party antivirus software is one of the most common causes of OnVUE problems on Mac. Applications like Sophos, Avast, McAfee, Kaspersky, and Bitdefender can intercept or block OnVUE's screen monitoring, webcam access, and network connections. Even if the antivirus is running in a passive or background-only mode, it can still interfere with the exam delivery system.
The simplest solution is to temporarily disable or completely uninstall your antivirus software before the exam. Most antivirus apps have a pause or disable option in their menu bar icon or system settings. Set it to disable for a specific time period (covering your exam duration), then relaunch OnVUE. If disabling is not sufficient, uninstall the antivirus entirely, you can reinstall it after the exam. macOS's built-in security (XProtect and Gatekeeper) provides adequate protection for the short duration of an exam.
Other third-party software that can conflict with OnVUE includes VPN clients (NordVPN, ExpressVPN, Cloudflare WARP), screen recording tools (OBS Studio, ScreenFlow), remote desktop applications (TeamViewer, AnyDesk), and display management tools (BetterTouchTool, Rectangle). Close all of these before launching OnVUE. Also check that no background processes from these applications are still running, use Activity Monitor (found in Applications > Utilities) to force-quit any lingering processes.
- Temporarily disable or uninstall third-party antivirus before the exam
- Use macOS built-in XProtect for security during the exam instead
- Disconnect VPN services, NordVPN, ExpressVPN, WARP, or corporate VPNs
- Close screen recording tools: OBS Studio, ScreenFlow, Loom
- Quit remote desktop apps: TeamViewer, AnyDesk, Chrome Remote Desktop
- Use Activity Monitor to force-quit any lingering background processes
