Hi there! I see you're having trouble opening the CarGurus site on your Mac with OS X 10.15.7. Let's get this sorted out together. Can you tell me a bit more? For example, are you using Safari, Chrome, or another browser? And when you try to open the site, does it give any error message, or does the page just stay blank or keep loading?

In the meantime, here are some initial steps you can try:

1. Clear Browser Cache and Cookies
Sometimes old cache or cookies can cause loading issues.
- On Safari: Go to Safari > Preferences > Privacy > Manage Website Data > Remove All.
- On Chrome: Go to Chrome > Clear Browsing Data, select cached images and cookies, then clear.

2. Try a Different Browser
If you're usually on Safari, try Chrome or Firefox to see if the issue persists. This helps identify if the problem is browser-related.

3. Disable Browser Extensions
Extensions like ad blockers can sometimes interfere with a site's loading. Disable extensions temporarily and reload the site.

4. Force Refresh the Page
On Mac, press Command + Shift + R to refresh the page bypassing cache.

5. Check Your Internet Connection
Ensure your internet is stable, or try connecting via another network if possible.

If you’ve tried any of these already, please let me know which ones, and if there are any error messages or behaviors you’ve noticed. This way, I can help you further, maybe with more advanced settings or checking if there are any known server issues.

Are you satisfied with trying these steps first? I’m here to assist until it’s working smoothly.

site not opening

Thanks for letting me know the CarGurus site still isn’t opening. Since you’re on a Mac with OS X 10.15.7, let’s dive a bit deeper.

You mentioned the site is not opening at all—does it give you an error, like “unable to connect,” or does it just keep loading? Meanwhile, here are some additional steps tailored for your situation:

1. Check if CarGurus is Down: Sometimes the site itself might be experiencing outages. You can check this on a site like isitdownrightnow.com by typing in cargurus.com. This will tell you if the problem is on their end.5

2. Flush DNS Cache on Mac: Sometimes stale DNS info can cause sites not to load.

- Open Terminal (you can find it in Applications > Utilities).

- Type this command and press Enter:

sudo killall -HUP mDNSResponder

- You’ll be prompted to enter your Mac password (it won’t show as you type).

3. Disable VPN or Proxy: If you’re using any VPN or proxy services, try disabling them—they can sometimes block access to certain sites.

4. Check Browser Privacy Settings: Some browsers block third-party cookies or scripts that CarGurus needs.

- For Safari: Go to Safari > Preferences > Privacy, and uncheck “Prevent cross-site tracking.”

- Also, temporarily allow all cookies and reload the site.

5. Try Accessing via Private/Incognito Mode: This disables extensions and uses default settings, which can help identify if something in your browser is interfering.

6. Review Network Settings:

- Restart your router.

- On your Mac, try renewing your DHCP lease: System Preferences > Network > Advanced > TCP/IP > Renew DHCP Lease.

Based on some community reports, the CarGurus app or site may occasionally have server issues, so trying again after some time can also help.1

Give these a try and tell me what happens. If the site still won’t open, I can guide you through more advanced troubleshooting or alternative ways to access the service.

Are you comfortable starting with these steps?
