Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
You have tried most of all troubleshooting steps so far. I believe the issue with your ISP. Have you tried accessing Facebook using different network connection ?
Now, lets change the DNS of your Mac.
Restart your Mac and try Facebook. Please let me know if that didn't work, so we can continue troubleshooting.
Remember, this is not my final answer. If my solutions didn't work please don't rate me bad or poor. Instead please reply back to me and I will continue to help you until we fix the problem or you are satisfied.
Are you sure your ISP is not blocking it ? Did you try with different WiFi network ?
Do this please. Go to Safari > Preferences. Click on Advanced tab and enable "Show Develop menu in the menu bar".
Close it. Click on Develop menu in the top and click Empty Caches. Try Facebook.
If that didn't work, click on Develop menu and select Disable Styles. Check Facebook. let me know the results please.
I understand, but I've seen this issue related to ISP. Trying on different network will tell us whether this is with your Mac or with ISP
You have already tried different browsers. Right ?
Take your time, we can continue later.
Open System Preferences and click on the Network icon. Unlock the pane if necessary by clicking on the lock icon and entering your password. Select Airport. Click on the Advanced button, then on the DNS tab. Click the + button and add the following DNS servers, then press OK and Apply.
If the above DNS doesn't work then use the following DNS
Make sure you delete the old DNS addresses there and add the only above one.
Then restart your Mac. These settings reflect on all browsers.
Also if you have any anti viruses or firewal application running in the background either stop them or delete/uninstall them and check Facebook
You don't have to delete other browsers. The reason I asked re different network is that some ISP block certain websites and Facebook could be one of them. But if others can access Facebook on their devices then it wouldn't be the network.
Try the above steps and let me know the results please.
I will opt out and send this question to other experts in here. If they have any idea, they will get back to you .
This is a strange issue. You've already tried all troubleshooting steps so far yourself. I'm sorry I'm stumped on this. So I will open this question to all other experts in here. If they have any idea, they will get back to you.
If no one get back to you, you can contact***@******.*** for full refund.
Please go to the Apple logo at the upper left of your computer screen to About This Mac and give me this information:
Also do you have any virus or security software?
OK do you have any Virus or security software installed?
Ok did you see my offer to remote connect? I can check for you while you watch.
OK we just needed to make sure the software is off because it as well as Adblock are usually the culprit. Facebook is really just one big ad. LOL You can also try upgrading to Yosemite.
Also this has worked for some as it resets your data you may have to do it on another computer:
