Safari won't load certain websites

Well, as far as I know my ISP doesn't provide IPv6 at the moment. I have a very basic broadband network anyway.

Does this mean that setting it to 'Link-local only' would disable the IPv6? I just wonder why there is no Off option..

Thanks!

You should ask them, but another way is to go to Test your IPv6 connectivity with it enabled and see for yourself.

Well that's what I said, but technically it will only disable IPv6 with respect to the Internet and will still be active on your local network (which shouldn't have any effect on speed).

Because you haven't used the required Terminal command to turn it off. I don't feel that most users needs to have their life complicated by something that isn't needed to have the desired effect.

MadMacs --

Personally, I would be completely upset if, for my Mac to work correctly, I had to use Terminal. That's just not right. If an inexpelrienced Mac user tried Terminal for the firsst time, he/she could very well render their Mac useless. Way to easy to make a one space or letter mistake.

I generally agree with that, which is why I didn't repeat what has been proposed by several others in related forum topics, using Terminal to turn IPv6 completely off. It isn't necessary to disable it's use on the Internet and could accidentally cripple a users system.

I do think that there is genuine use for Terminal in the troubleshooting business that often cannot be accomplished by any other means. We have all observed how somebody like Linc Davis can craft a procedure to get quickly to the bottom of an issue and still make Terminal user almost foolproof by through his cautionary words and formatting of complex commands.

Admittedly, we now have EtreCheck to accomplish much of what those Terminal commands have had to do in the past, but it still doesn't do it all, nor can it be tailored to focus on a specific issue.

I'm sure I've seen fixes that can only be accomplished via Terminal, but I can't recall any of them off the top of my head at the moment. If I ran across one, I wouldn't hesitate to offer it with appropriate cautioning instructions.

Because I am using Mavericks, I have the same issue: can't turn off IPv6 since it's not an option... however I did find changing the DNS server settings to 8.8.8.8 and 8.8.4.4. did the trick for me.

It's no different in Mavericks than it has been in the past. You don't get an "Off" option unless you use the Terminal app to turn it off. Selecting "Link-local only" accomplishes the same thing should you dislike using Google public DNS for any reason.

Hii! I'm glad I found your answer here and solved your problem. I tried to follow your idea but at the very end, I found out my choices are automatically, manually and Link-local only. There's no way for me to OFF it just like yours. huhhh! 😢

Now, I keep hoping and finding the solution.

Setting it to Link-local only will serve the same purpose.

Hi MadMac0,

I've discovered a few idiosyncrasies that I just can't wrap my head around. Any help or suggestions would be greatly appreciated.

My machine is: late 2008 iMac w/4 GB RAM running Snow Leopard (10.6.8). That being said...

1). When I'm @System Preferences->Network->Advanced...(lower right button)->TCP/IP(tab)->Configure IPv6:-> is OFF. Also, please note there is no link-local setting on my older machine & OS. 😟

2). When I'm @Network->Advanced->Proxies->Use Passive FTP Mode (PASV) is deselected

3). When I'm @System Preferences->Security->Firewall: ON -> Advanced-> Enable Stealth Mode: selected

I've noticed some glaring discrepancies, however, when using Apple's proprietary System Profiler Version 10.6.0 (217).

And those discrepancies are quite clearly revealed; not to mention they are (apparently) quite the opposite of the preference options that I purposefully selected. I'd also like to note that I subsequently tested them all via the well-known method of 'toggling'. Fuhgeddaboutit.

1). IPv6 is ON (I assume by default) as well as the paradoxical -> IPv6: Configuration Method: Automatic

2). FTP Passive Mode: YES

3.) Stealth Mode: NO

Thanks in advance to you or any other Community Members that may understand why so many of one's preference choices seem to be overridden. 😕

Best Regards,

mm~

Edit: Oh, I forgot to mention that I did a test that you recommended @ http://test-ipv6.com/

Part of the results were:

Good news! Your current configuration will continue to work as web sites enable IPv6.

Your DNS server (possibly run by your ISP) appears to have IPv6 Internet access.

Good thing that I selected -> Configure IPv6:-> is OFF.

You're lucky I stumbled on this as I usually unsubscribe from old conversations that are solved.

It would certainly appear to be a preference file corruption and it doesn't appear to be one I'm at all familiar with, but I think I've finally tracked it down at:

/Library/Preferences/System Configuration/preference.plist

This isn't your user or System Library, but the one at the root level of your hard drive.

It appears to have a lot of Network preferences in it, so be sure you have written down all your Network settings, including Advanced so you can restore them. Also write down your Computer Name from the top of the Sharing preference pane.

Make sure you have a solid backup or two (Time Machine preferred) in case something goes wrong.

Quit System Preferences if it's open.

Drag the preference.plist to your desktop where it will be copied in case you need to put it back. Now drag it to the trash and authenticate with your admin password.

Open System Preferences->Network and you should find everything blank.

Click on the Location: menu and select Edit Locations...

Type in a location name (recommend something other than Default).

Restore all settings.

Got to System Preferences->Sharing and restore the name of your computer.

There could be other settings that need to be restored, but those were the only ones I recognized.

If that doesn't solve the problem or causes other issues, trash the new preference.plist and restore the old one from your desktop or Time Machine/backup.

I came across this thread while searching for a solution to the same issue - couldn't get any Yahoo pages, or pages that called on Yahoo resources, to load. I turned off IPv6 in Network Preferences and it immediately fixed the problem I had. Thanks DallasTwinMom for the solution! Prior to this I had tried different browsers and a new user account and the behaviour was the same. I decided to keep checking, as I know it only affects my home computer - my work machine, not far away but on a separate connection, works fine - so I tried my iPhone 5.

It uses the house modem to access the internets via WiFi and, sure enough, it showed the same behaviour as does my iPad. Once I turned WiFi off on the phone, causing it to use its own connection, it too could access Yahoo.

This leads me to believe that my modem, a Billion BiPAC 7800N, is actually the cause in this case. This may possibly be true for others and could explain why this problem exists but is not widespread. I don't know how to change the config on the modem to solve this and found nothing on the Billion forums, but I can live with the issue for the time being. Thought I would just add to this thread in the hope that someone else might find the extra info helpful.

It would appear that your modem is IPv6 capable, but may not have been configured as such (See Configuring your Billion 7800N for IPv6)

Another possibility is that you ISP hasn't fully rolled out IPv6 or has established some sort of workaround DNS service that is at fault. You would need to contact them to find out where they are on that.

As you have probably read here, it's not a big deal for most users to not be able to use IPv6 as there are very few sites that can't be reached using IPv4, but over time that will change and there are already such sites in Asia.

Thanks for the response MadMacs0.

As it happens, I'm with Internode, bought the modem from them and it came preconfigured exactly as per the instructions on that link. So, still not sure what might be going on here, but I may well have a new modem by the time I need to use IPv6.

I found this on another post, and literally after trying EVERYTHING possible (or so I thought) for over 8 hour straight, this was the trick that fixed it! I have to share with anyone else who is as frustrated as me...

"Not sure why this worked but I created a new location under Application - System Preferences - Network - Location - Edit Locations - Add ➕ - Done. Make sure you click on the Wi-Fi on the left and now all websites are loading"

I tried pretty much all the reasonable suggested solutions -- none seemed to work for me or they seemed to work for a short while but the failure to reliably load web pages in Safari on my iMac would still recurred after a little while -- very frustrating!

My solution: Using Time Machine, I finally tried restoring my 10.9.5 Mavericks OS to the vintage from a time when there wasn't a problem. I had to restore my personal files to the latest too, but it works great now! The process took about 1 hr.

I believe the problem was definitely related to the OS or Safari (which is integrated into the OS) but I don't know if it was a system update bug problem or some sort of malware that caused some sort of corruption.

Copied from Apple support website, this was for reverting Yosemite back to a previous OS X but the same process concept works for reverting back to any previous OS X version or vintage as well:

If you use Time Machine to back up your Mac, you can easily revert to a previous version of OS X if you experience trouble after installing an update.

1. Print these instructions.
2. Choose Apple menu > Restart. After your Mac restarts and you hear the startup chime, hold down the Command (⌘) and R keys.When the Apple logo appears, you can release the keys.
3. Select “Restore from a Time Machine Backup,” then click Continue.
4. Select your Time Machine backup disk.
5. Select the Time Machine backup you want to restore. To restore your computer to the state it was in before you installed the new version of OS X, choose the most recent backup that occurred prior to installing OS X Yosemite. [In my case, I selected the OS X version vintage from a time that didn't have the problem].
6. Follow the onscreen instructions.

If you backed up files as described in the Important message above, you can restore them now. If you backed them up using Time Machine, click the Time Machine icon in the menu bar, choose Enter Time Machine, then retrieve your files.
