How to Fix Website Access Issues on Safari for iMac?

To troubleshoot the issue with accessing Facebook and Shutterfly on Safari, start by checking your browser settings. Open Safari and go to Preferences, then select the Security tab. Ensure that you have "Accept Cookies" set to "Always" and that JavaScript and other necessary plugins are enabled. Next, check your network settings. Go to System Preferences, then Network, and click on Advanced. Under the DNS tab, add the DNS servers you want to use. Also, in the TCP/IP section, make sure to configure IPv6 to "Off." After making these changes, restart Safari and see if that resolves the issue. If the problem persists, try clearing any cookies related to Facebook. In Safari Preferences, under the Privacy tab, ensure that you have "Never" selected for blocking cookies. Additionally, check the Extensions tab to make sure no extensions are interfering with your browsing experience. If you still can't access these sites, consider checking your firewall settings. Go to System Preferences, then Security & Privacy, and click on the Firewall tab. Make sure it’s set to allow all incoming connections. If it’s already set correctly, try temporarily turning off the firewall to see if that makes a difference. If none of these steps work, you might want to try booting your computer in Safe Mode. Hold down the Shift key while restarting your Mac, and keep holding it until the computer fully boots. This can help resolve any underlying issues. After booting, try accessing Facebook again. Lastly, if you have a different browser like Firefox, check if the issue is specific to Safari. If it works on another browser, it may indicate a problem with Safari itself. In that case, consider updating Safari or reinstalling it if necessary.
