Mac connects to network with no problem but browsers can't connect to websites

Question

I am using macOS Mavericks (10.9.5) and Chrome, Firefox, and Safari all do not connect to websites even though the network is clearly connected.

But browsing when booted into safe mode works.

I've read many articles and tried the following solutions:

  1. Set DNS servers to Google DNS and open DNS.
  2. Reinstalled operating system through the internet recovery. The internet for the recovery worked as expected, so this issue is something specific to browsing.
  3. Added Chrome, Firefox, Safari to Mac firewall.
  4. Removed System Configuration folder from library/preferences
  5. Disabled McAffee antivirus put on by work IT
  6. Ran McAffee scan and found nothing
  7. Renewed DHCP

Anyone have any ideas?

Was it helpful?

Solution 3

Turns out that HBSS was preventing browsing due to not having the latest McAfee updates.

Thanks to all who helped me through this!

OTHER TIPS

Turns out my AV had entered a proxy that was blocking my connections.

It might be worthwhile to check: System Preference > Network > Choose your connection > Advanced > Proxies > remove any active proxies

I had my iMac in storage for one year and when I started it up again although I could see that the wifi is connected I could not browse the internet. I contacted Apple Support and after deleting the contents of the folders below, the problem was solved.

Folders the contents of which were deleted are listed below:

~/Library/LaunchAgents

~/Library/LaunchAgents

~/Library/LaunchDaemons

I have experienced for a few days the same issue on MacOS Sierra (10.12.5). No one of the suggestion found on internet seemed to work.

Finally, while installing the "Little Snitch 4 Public Beta" to check firewall trouble, the browser functionality suddenly springed back. I also choose to 'force quit' the installation to avoid to shut down or restart my Mac.

I guess that the Little Snitch installation overwrited some files, resolving the issue, without ever have to restart browsers or computer.

Just faced the same issue after a recovery from Time Machine.

I had access to the internet but the applications refuse to connect except App Store and Apple Website on every browser.

I just deleted Little Snitch and the two files of Launch Deamons and Launch Agents and everything got back to normal.
