How to fix 'Your clock is ahead” error

The "Your Clock Is Ahead" error prevents website access, but it's rarely a virus. This guide explains how to fix this common Mac issue, usually caused by incorrect time settings.

Why This Happens:

Your browser verifies a website's SSL certificate before connecting. If your Mac's clock is ahead of the certificate's validity period, the error appears. Common causes include:

• Incorrect date and time (especially manual settings).
• Mismatched time zone and region settings.
• Outdated or corrupted browser cache and cookies.
• Expired website security certificates.
• Internet connection problems.

Tip: Use WiFi Signal (available on Setapp) to quickly check your internet connection's health.

Solutions:

1. Set Automatic Date and Time:

   Go to Apple Menu > System Settings > General > Date & Time. Enable "Set time and date automatically," ensure the source is time.apple.com, and enable automatic time zone setting. Restart your Mac afterward.

   Alternatively, use the Terminal:

   1. Open Terminal (Command Space, type "Terminal").
   2. Run: sudo sntp -sS time.apple.com or sudo sntp -sS in.pool.ntp.org (enter your password).

2. Check Language and Region Settings:

   Go to Apple Menu > System Settings > General > Language & Region. Verify your region is correct. Try changing it temporarily and then resetting it.

   

3. Clear Browser Cache:

   • Safari: Go to Safari > Settings > Advanced, check "Show Develop menu," then Develop > Empty Caches. Alternatively, go to Safari > Settings > Privacy > Manage Website Data > Remove All.

   

   • Chrome: Settings > Privacy and Security > Clear Browsing Data. Select "All time," cookies, and cached images.

   

   • Firefox: Firefox > Settings > Privacy & Security > Cookies and Site Data > Clear Data. Clear cookies and cached web content.

   

4. Update macOS:

   Check for updates in Apple Menu > System Settings > General.
