Solution 1: Update Logi Options+ (Recommended)

Official Fix from Logitech

Logitech has released an updated version of Logi Options+ with a renewed certificate:

Latest Version: Logi Options+ 1.72 or later (released January 10, 2026)

How to Update

If Options+ Opens (Even Briefly):

1. Open Logi Options+
2. Click your profile icon in the top-right corner
3. Select Check for Updates
4. Install the latest version
5. Restart your Mac after installation

If Options+ Won't Open:

1. Download the latest version directly from Logitech:

   • Visit logitech.com/software/logi-options-plus
   • Click Download for macOS

2. Before installing, completely remove the old version:

# Close any running Logitech processes
killall "Logi Options+" 2>/dev/null
killall "Logi Options Daemon" 2>/dev/null
killall "LogiMgr" 2>/dev/null

# Remove the application
sudo rm -rf "/Applications/Logi Options+.app"

# Remove supporting files
rm -rf ~/Library/Application\ Support/Logitech
rm -rf ~/Library/Preferences/com.logitech.*
rm -rf ~/Library/Caches/com.logitech.*
rm -rf ~/Library/LaunchAgents/com.logitech.*

3. Restart your Mac

4. Install the downloaded Logi Options+ package

You should see output indicating a valid Apple Developer certificate with a future expiration date.

   • Right-click (Control-click) on Logi Options+ in Applications
   • Select Open
   • Click Open in the security dialog

Using xattr to Remove Quarantine

# Remove quarantine attribute from Logi Options+
sudo xattr -rd com.apple.quarantine "/Applications/Logi Options+.app"

sudo xattr -cr "/Applications/Logi Options+.app"

Restart the app after running these commands.

Preventing Future Certificate Issues

Why This Happened

Developer certificates have expiration dates (typically 1-5 years) for security reasons. Companies must renew certificates before expiration to prevent exactly this scenario. Logitech failed to renew their certificate on time.

How to Protect Yourself

1. Keep Software Updated: Enable automatic updates in Logi Options+
2. Have Backup Settings: Export your settings regularly
3. Know Alternative Software: Familiarize yourself with SteerMouse or similar tools
4. Monitor Logitech Communications: Follow @LogitechSupport on Twitter/X

Logitech's Response and Prevention

Logitech has stated they are implementing:

• Automated certificate renewal monitoring
• Earlier warning systems for upcoming expirations
• Improved testing of certificate-dependent features

FAQ: Common Questions About This Issue

Will this affect my device warranty?

No. This is a software issue caused by Logitech, not hardware damage. Your warranty remains intact.

Do I need to return my Logitech device?

No. The devices themselves are fine. This is purely a software/certificate issue.

Is this a security risk?

The expired certificate itself isn't a security risk. However, disabling Gatekeeper or allowing unsigned apps (as some workarounds suggest) does reduce security. Use the official updated app whenever possible.

Will this happen again?

It shouldn't. Logitech has stated they're implementing systems to prevent certificate expiration issues in the future.

Are Windows users affected?

No. This issue only affects macOS due to Apple's code signing requirements.

My device is working fine without Options+. Do I need to fix this?

If basic functionality is sufficient, you can continue using the device without Options+. However, you'll miss advanced features like:

• Custom button assignments
• Gesture controls
• Per-app settings
• Logitech Flow
• DPI switching

Conclusion: Logitech Certificate Issue Resolution

The Logitech certificate expiration incident of January 2026 caused widespread frustration among Mac users. However, Logitech responded relatively quickly with an updated application. For most users, simply downloading and installing the latest version of Logi Options+ resolves all issues.
