Have you ever encountered the dreaded 4 Fixes For Kernel Driver Not Installed (rc=-1908)” error on your Mac? If you have, you’re not alone. This error can be a real headache, preventing you from using certain software or hardware devices. But fear not, I’ve been through this, and I’m here to share my experiences and some tried-and-true fixes to get you back on track.
1. Reinstall the Problematic Software
Often, this error occurs when you’re trying to use software that relies on kernel drivers, like virtualization tools or antivirus programs. If you encounter the “Kernel Driver Not Installed” error, it might be a case of a corrupted installation. Here’s what you can do:
- Uninstall the Software: First, remove the problematic software completely. Use a trusted uninstaller tool or follow the software developer’s instructions for removal.
- Reboot: After uninstalling, restart your Mac. This step can help clear out any lingering issues.
- Reinstall the Software: Download the latest version of the software from the official website or the Mac App Store. Install it fresh.
- Update macOS: Ensure that your macOS is up to date. Kernel driver issues can sometimes stem from compatibility problems with outdated operating systems. Go to “System Preferences” > “Software Update” to check for updates.
2. Check for Unsigned Kernel Extensions
Kernel extensions (kexts) are vital components for many drivers on macOS. However, Apple imposes security measures to protect your system, and not all kexts are allowed to run. If you’ve recently upgraded your Mac or installed new software, this might be the root cause:
- Open Security & Privacy Settings: Go to “System Preferences” > “Security & Privacy.”
- Unlock the Settings: Click the padlock icon at the bottom left and enter your administrator password.
- Allow Blocked Kexts: Under the “General” tab, if you see a message about blocked kernel extensions, click “Allow.”
- Restart: After allowing the blocked kexts, restart your Mac to apply the changes.
3. Repair Disk Permissions
Disk permissions can sometimes get messed up, causing various issues, including kernel driver errors. To fix this, you can use Disk Utility:
- Launch Disk Utility: You can find it in “Applications” > “Utilities.”
- Select Your Disk: Choose your Mac’s startup disk from the sidebar.
- Click “First Aid”: Then, click “Run” to check and repair disk permissions.
- Restart Your Mac: After the process is complete, restart your Mac to see if the error is resolved.
4. Consult the Developers and Community
If you’ve tried the above fixes and still can’t get rid of the “Kernel Driver Not Installed (rc=-1908)” error, it’s time to seek help from the experts:
- Check Official Support: Visit the official website of the software or hardware causing the issue. Look for support forums or contact the developer’s support team directly.
- Online Communities: Websites like Stack Exchange, Apple Support Communities, or Reddit’s r/Mac can be invaluable resources. Search for your specific error or post a question with details about your problem.
Remember, tackling these technical issues can sometimes be a bit of a trial-and-error process. It’s always a good idea to back up your important data before making significant changes to your system. Also, be cautious when allowing unsigned kernel extensions, as they can potentially pose security risks.
