Mac OS 10.12.4 Can't Connect Many Apps to Internet

Since Mac OS was updated to 10.12.4, Norton will not work properly in many ways. It does not let apps access the internet, let's some apps access the internet, will not update the virus definitions, says it needs to fix itself, but fails to do so. I'm seeing plenty of the same issues being discussed on other forums as I search for a solution. Uninstalling and reinstalling does not help, same problems persist. 

When will this be resolved?

I have also encountered this issue. When I logged on to my computer, I was unable to connect to the Internet via several programs. I was able to get around the issue by switching to a WiFi connection rather than using Ethernet. I prefer the security of ethernet, though.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Thanks for the reply. This happens with wifi or e-net. Norton is aware of this, so they say, with the Mac OS 10.12.4 so I was wondering if anybody has come up with decent ways around this for a temporary solution.

This problem is pretty serious. I cannot connect to QQ; and my school wifi (eduroam) is often blocked. Making exceptions in "connection protection" in the firewall does not help. My current solution is to turn of connection protection in the firewall setting.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

I've been experiencing these issues as well and was told by online help that I would just have to keep restarting my Mac and trying to apply updates and scans manually rather than using Fix Now. This works only sporadically. I've spent so many hours doing this that I finally just shut the Mac down. I'm considering getting rid of norton security entirely if I don't hear this is fixed very soon. It's unacceptable that it's gone on this long.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

And if you do some searching out in the rest of the world, you will find plenty of 10.12.4 users talking about this problem. It started before 10.12.4, but was not as bad. Versions of Sierra before 10.12.4 would cause some halting behavior, but recovered quickly and connected. But Norton is just unusable with Sierra 10.12.4. 

I did an uninstall and reinstall with tech support, and the computer worked fine for about an hour or so before all the random and chaotic app online disconnections happened. The computer also works great without Norton installed.

Gentlemen. I have forwarded the link to this thread to the gurus asking them to get someone at the engineering level involved. Hopefully someone will post something here and get the ball rolling ASAP. Will follow up on a regular basis to ensure its not forgotten. In the meantime I am posting a link to the latest on the MAC Norton release, there are FAQ's which may shed some light on what the update entails. Have a grand Sunday.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Fiddling with Application Blocking does not change anything for me. I turned it off completely and no difference. There seems to be something else that causes this and cascades.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Hi everyone,

Thanks for reporting this issue.

Just to narrow down the cause, could you confirm if turning off the "Connection Blocking" setting under firewall fixes this issue?

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Turning off the "Connection Blocking" setting under the firewall does NOT fix the issue. 

Even with "Connection Blocking" turned off, the performance of the computer is still affected. Connection of browsers to sites is halting and slow, very slow. Connections online of other apps are slow and delayed. With "Connection Blocking" turned on, it is far worse. Some apps will be totally unusable, and it changes. Some apps can then connect, while others are then affected and can not connect. It is very strange and changing. I can not see a pattern, it seems to be random and chaotic. 

So even with "Connection Blocking" set to off, the performance of the computer is still affected.

A few days ago, I was working with Tech Support on this, and we did a super complete uninstall of Norton, and then reinstalled Norton. It was set up with "Connection Blocking" to "on". The computer worked great for about 2 hours. I did two complete system scans, and connection of apps online was very fast, as if Norton wasn't even there. Then it started having problems, and made the computer unusable. I turned off "Connection Blocking" and other firewall protections, and the computer is usable, but still halting online connections. I think "Safe Web" might have something to do with that. Norton will not let me turn off "Safe Web", it turns "Safe Web" back on immediately when I switch it off.

And make sure you also consider the Norton browser web extension.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Norton will not allow a manual scan to be started. When I click the button to start a scan, it sits there for a few seconds, then reports a Scan Error - Fix Now.  However, I have seen notifications that idle scans are still being performed.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

The performance of the computer has been hobbled since Mac Sierra was released and running Norton. Even Mac OS 10.12.3 and earlier were not free from problems from Norton, just not as bad as now. To be clear, the computer runs fine without Norton installed. Norton has not kept up with the new releases of the Mac OS. Mac OS before 10.12.4 were halting, but never as bad as now where Norton renders the computer unusable.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Hi,

Running Mac OS 10.12.4 I haven't uninstalled NIS but to be able to use the internet on my Mac I turned off all Norton Firewall settings and all automatic updates on the Antivirus settings. This lets me keep the program installed while still surfing the web. The only things that are on right now are Safe Web and File Guard and those don't give me problems. As a temp fix I enabled Mac OS' own firewall. Currently waiting for the fix to turn everything back on. Screen grab of my settings.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

I am having same issues.  Apple uninstalled Norton and everything worked.  I contacted Norton they reinstalled the program last night, almost immediately reverted to unable to connect.  Uninstalled Norton and everything worked.

this needs to be fixed now, seriously considering dumping Norton permenantly.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Turing off "Connection Blocking" reduces the problem, somewhat, but does not remediate the problem. There is still a halting connection behavior, sometimes it takes a long time for an app to go online, as in minutes. 

Kudos0

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

I started a similar thread about this as well and they claimed a week ago to be working on a fix.  For me and a colleague turning off "Connection Blocking" reduced the problem.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Turning off "Scan files in Compressed Archives" resolves the issue for me.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Geoff B., does that make sense?

When you started seeing these problems, did you think that the solution must be to turn off "Scan files in Compressed Archives"? 

The symptoms, conditions, etc. seem to be chaotic.They are definitely unpredictable, random, and intermittent.  At best, these things like turning off this or that are workarounds, not a solution to a root cause. None work for me. Clearly, NIS needs to be revised to be FULLY compatible with Mac OS 10.12.4. 

Kudos0

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

No, possibly not! But I found it stopped SymDaemon hogging CPU on 2 of my 3 Macs (The third one works perfectly without changing any settings). Its obviously not a solution, I only offered it as a possible workaround until Norton fixes the problem - and I'm on their case like everyone else.
Kudos0

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Geoff B, thanks for letting us all know that turning off the scanning compressed documents feature has a positive effect. That could be the secret to solving this problem. At least the programers will know where to look when it comes to analyzing the millions of lines of code that comprises NIS.

While you personally did not find a cure to this disease you might have found the loose joint responsible for breaking this program. Until it is fixed I would prefer to preserve the ability on my computers to scan compressed files because once I've opened any infected but unscanned file my Mac could be finished! LOL!

So for the time being I am back to running NIS on Mac OS Sierra 10.12.3 on three machines with no problems at all so far. Try to keep in mind, everyone, that fixing this problem could take weeks and / or months to accomplish. Knowing this, everyone should pick a long term solution that they are comfortable with and patiently wait for the inevitable repair!

Kudos0

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

The only functionality I have left turned on is Safe Web, Automatic and Idle Scans. Otherwise, I am afraid to touch NIS. NIS does report that it has completed Idle Scans. Interesting since it will not invoke a manual Scan anymore.

The App Store and Mail are two apps that seem to be hobbled the most, almost always taking a long time to go online, and then randomly going offline.

I have not added or changed anything other than updating to Mac OS Sierra 10.12.4 to bring about these issues.

Keep reporting all anomalies, symptoms, etc. here so hopefully it can be compiled to help figure this out. 

Norton people, post questions here, perhaps ask people to do tests.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Isn't this why ISV's such as Symantec/Norton get early release (beta) access to Mac OS (or macOS or whatever they want to call it this week)?  So that they can get ahead of possible issues such as this.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Hi everyone,

Thank you for your patience.

While our engineering team investigates this issue, Could you please follow the below instructions and see if it resolves or reduces connectivity issue?

  • Open Norton program
  • Click on Advanced Pillar
  • Under the Protect My Mac >
  • Disable Idle Scans
  • Reboot the Mac

Once the mac reboots

  • Check if Idle Scan is still disabled
  • Now please check for the connectivity issues (launch browser and access internet)
  • If you still face the issue, Please reboot again

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Hi,

So I enabled everthing back on except the idle scan, rebooted my Mac and so far no connectivity issues. All apps can connect to the internet. I'm going to paste pics of all the settings on my NIS so you can check what's on.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Spoke a bit too soon. My internet connection remained on but SysDeamon was hogging my CPU, running at over 100% or at 100% all the time. Tried to open Word and got the wheel of death. Turning all my settings to off like before didn't help so I did a clean uninstall of Norton for now. Will PM a sample of the process to you (couldn't get a sample using Activity Monitor by the way, it hangs and never presents an output - had to use terminal to get it).

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

This test did not prove to be helpful. 

Disabling "Idle Scan" and rebooting did not help.

The computer should operate as if NIS wasn't installed, that did not happen.

There was still halting behavior, and some apps still took a long time to go online.

Another symptom is that Mail, App Store, Safari, and iTunes often take a very long time to close when ordered to Quit. It's like the spinning color wheel hang mode without the color wheel.

Keep going... let us know if it remains that way.

I have had just about everything turned off and NIS still interferes with the computer, preventing apps from going online, dropping online connections, delaying apps from quitting, etc.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

The only parts of NIS that I have still active are DeepSight, Safe Web and Error Management. Safe Web is on because it won't stay off, it turns itself right back on.

Why does Safe Web not stay off when turned off?  It turns itself on immediately.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

What's new here?  Norton, any progress? 

I have some interesting observations. 

In the Advanced - Firewall panel, I went into the Application Blocking option by clicking on the button with the wrench and screwdriver. That then opens a panel that can be populated with apps that access the internet, with the option to allow or block that app. In the past, I never populated this panel. So now I have this panel populated with apps that I guess are now scrutinized by NIS. With all these apps now listed in that panel, the performance of the computer is MUCH better, not perfect, not as if NIS is transparent, not as if NIS was not installed, but much better. Also, if an app tries to access the internet and it is not in this list, a popup window will ask if you want to allow or block that app. I think that app is then added to the panel list under Application Blocking.  So by adding apps to this list, the performance of the computer has gotten much better, but still not completely right. 

The computer can not do Scans, that option is always red in the NIS window, and I can not manually invoke a scan. Live Update seems to work better and faster. In the Protect My Mac window, I have all Scan options turned on, and in the Firewall window I have all options turned on, and I have populated the Application Blocking/Allow panel with apps. Populating that Application Blocking/Allow panel with apps has helped the performance of the apps in getting online and staying online. There is still some occasional halting or delays, I sometimes have to restart, but nowhere near as bad or as often as without the Application Blocking/Allow panel populated with apps. The App Store, iTunes and Twitter are now the apps most likely (more often) to have connection/online issues. 

So I now have everything turned on in the Protect My Mac and Firewall options, the Application Blocking panel is now populated with a list of apps and the computer runs much better. Live Update works, or appears to work.

The bad is that scans do not seem to be working and they can not be manually invoked, hence Security and Scans stay in red, and there is still unacceptable app connection/online issues.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

I have the same issues and spent some time at my local Apple store trying to resolve them. The only solution was to de-activate Norton. I have since uninstalled it and am now using a different security product - and all is well. Pity I'd just paid my Norton subscription, something I must cancel for the future. MY MacBook is now working just as it always did.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

Appreciate the comments, but the only real solution can come from Norton.

NIS has to be updated so that all of its features can be used as selected by the customer, not by what makes the product less detrimental to the user experience. That disabling "Archived Files" helped is perhaps useful for Norton as they seek and develop a solution. I've tried about every combination of settings and the results are random, completely erratic. 

If a LiveUpdate is pending, the computer and apps will be prevented from going online. It still seems very random, intermittent, and chaotic. I have yet to identify precise conditions that cause the apps to not go online.

Re: Mac OS 10.12.4 Can't Connect Many Apps to Internet

You are right. It is indeed only a temporary solution but so far it's working. The ball is still in Norton's court. The Mac version of Norton is a very bad piece of software and should be rewritten from the ground up. It's an endless story for years now. Everytime Apple updates their software, Symantec needs months to change Norton.

Let's see how this goes for a few days. I'll try just about everything EXCEPT Application Blocking for a couple days, see how it goes. Maybe I'll try Application Blocking in a couple days.

I am terrified to turn on Application Blocking, that's what was causing all sorts of issues for me.
