Connectivity issue using 10.11.3 (15D21)

Updated my iMac to latest version of iOS -- 10.11.3 (15D21) -- first thing this morning. Now, most websites don't appear to load properly.


Using both Chrome (default browser) and Safari (test browser), Facebook, Twitter, Youtube, and Gmail all work fine, but CBS News, The New York Times, my own, and others seem to be perpetually loading...


My phone is hooked up to the same router / modem as my desktop, also runs Chrome and experiences no issues with any of these websites.just


Why can't Apple test stuff before sending it out? Seriously... Every new patch brings about a new set of issues. It's awesome to be on the customer side of that relationship...

iMac, OS X El Capitan (10.11)

I just installed OS X 10.11.3 today and lost connectivity and could not browse the internet. I am running ESET Security Pro for Mac.


Turning OFF ESET did not fix the problem but completely uninstalling ESET and rebooting did fix the problem and all runs normally now without ESET.


There is clearly a compatibility issue between ESET and OS X 10.11.3 -- your machine is effectively rendered unusable with 10.11.3 unless you completely uninstall ESET.


The uninstaller for ESET is located within the ESET package. You go to Finder, right click on ESET, and if you fish around in the subdirectories you will find the UNINSTALLER app. Uninstall ESET, reboot, and your problem will be fixed.

FYI:

Just spoke with ESET. The official fix is not to uninstall ESET and then re-install it. The official fix is for them to access your computer and remotely swap out a file. They have not tried to uninstall and re-install so they can't vouch for that as a fix. They have not rolled out that file needed as part of the install package.


By their own admission there is a very limited threat that they protect against on Macs, but they did mention some malware.

One of the main pitches was protecting Windows machines during file transfer.

Picture this, your friend runs a Windows computer. S/he gives you an infected file. Your Mac is unaffected. You give this infected file to someone else with a Windows machine. That computer is now infected. ESET prevents that by detecting the file on your computer.

The rep also said that while the threat right now is minimal, you just never know.

Really bad idea.

When there is a threat to the Mac, that Apple's own XProtect does not deal with, and Apple never deals with, then consider an anti-virus.


Let your Windows friends protect themselves. As you have seen, this is yet another anti-virus package that is harming your Mac, not helping.

Speckta, thank you for your update.

Uninstall and re-install ESET doesn't work. At least, for me, it didn't (I tried it before my first post in here).

For security reasons, I don't want them to remotely access my computer.

If possible, they should tell me what to do. If not, I prefer not use ESET than let them remotely access my computer.

I understand that it could be a temporary measure for their convenience. However they should release a new version as soon as possible.

Regarding what ESET rep said, I agree with it:


In network security (and in epidemiology, by the way), carriers are almost as important as infected ones. Security software for mac (and even for Linux) is particularly important in multi-enviroment ecosystems. That's a main reason I use ESET, Kaspersky or other.


But don't get me wrong, let me emphasize it: for now (nobody knows the future: 0day malware), there are some (not that much, comparing with Windows and Android) malware targeting Mac (even fewer targeting Linux). But it only needs one of those to be successful and potentially jeopardize me. I don't blindly trust Apple, as I don't blindly trust ESET (or any other software company)... as I don't blindly trust me. Everyone knows that user is the biggest exploit, I don't mind have a little help.


But, despite this, I have to recognize it: OS X targeting malware wasn't the reason I choose ESET Cyber Security Pro.

Any good reputed modern security company has software that does much more than only detecting malware.


I wanted a good both way firewall (OS X firewall is one way only, if I'm not mistaken) that would let me control my traffic out (OS X firewall only controls traffic in, I think). That's other main reason I use it, as I used little snitch and others before.

(off-topic: I also recommend ports monitor software. Very important too: privacy software (VPN if you can afford it, anti-tracking, browsing security, etc)

ttlondon,

Thank you for your concern.


That's what I did.


I only reinstalled ESET to test what would happen.

( In the past, this procedure had solved me some problems with other apps after some OS X updates. But sometimes, it had not: for instance, Evernote problems with 10.11.x were only solved later by Evernote company with new version(s) ).


I did this last wednesday, before even write in here my first post. Then I uninstalled it, did what you said and leaved my computer that way.


For now, I'm waiting for an ESET response to this problem.

I can confirm this problem. We finally got to the solution because we had 3 computers, 1 installed with BitDefender and 2 with Eset. We tested dozens of ideas over 2 days before realizing the unaffected computer had a different anti-virus ...

Uninstalling Eset fixed everything.

I installed Bitdefender a while back on one of the machines because it's a 64bits app, Eset was the last 32bits app on Activity Monitor.

Incredibly bad idea and rationale.

FYI: ESET emailed me about an hour ago (22 Jan 2016) and told me their developers have found the problem and are now putting a fix. There will be a new release shortly within a day or two that fixes this issue.

My advice, in a day or two pass on installing ESET or any other third party app that claims to protect, boost performance, monitor, manage, your computer.

Jan 22, 2016 9:36 AM in response to Speckta

ESET HAS FIXED THE PROBLEM! As of 1 hour ago (16:30, or 4:30pm, GMT London time), all you need to do is open ESET (I right click on ESET icon and select Open), then manually trigger/force an UPDATE of the virus definitions, let it download, the restart your Mac, and it works!!


The problem with my machine was that ESET stopped all UPLOAD (not download) data, so websites which are waiting for a response when you open them where not getting any data back.
