how to remove 'stags.bluekai.com' pop up

This is not a malware or adware issue.

This is a certificate issue associated with visiting eBay in most cases.

To the best of my knowledge and from feedback I received, upgrading macOS resolves the issue.

I am just sharing the information I have.

When you visit sites that host ads, sometimes you get redirected to other sites where the ads are hosted. The certificates used on those sites are supposed to have all the correct host site names so that they can be used for the current URL.

There is a certificate problem somewhere in Bluekai, that has yet to be resolved, that puts up a certificate that does not list the current URL as a possible user of the certificate being proffered. Your Mac objects, and puts up an error box, essentially, "certificate proffered does not match the URL you entered, it may be an imposter site".

This is not a pop-up. Nor is it a problem on your computer. It is a correct indication that there is a certificate issue somewhere in that chain. Bluekai needs to fix broken their certificates before it will go away.

Because the browsers shipped in 10.9.5 work a little differently, the problem shows up more often in 10.9.5. You can get away from it if you decide to run a later browser in a later MacOS. You are Not required to upgrade.

Eventually Bluekai will either fix this problem or go out of business.

Choose History > Clear History, click the pop-up menu, then choose how far back you want your browsing history cleared.

BlueKai is a service provider to sites like eBay.

This problem affects mainly macOS Mavericks 10.9.5 users.

Upgrading macOS to macOS High Sierra 10.13 will help.

8GB RAM installed will work.

macOS High Sierra technical specifications:

For checking the compatibility of applications already installed on your Mac: https://roaringapps.com

Note: Newer versions Apple applications may work a little different.

Some older peripherals may not work.

Backup your Mac before installing the upgrade.

Not actually a pop-up. I keep getting a drop-down window regarding identity of the web site "stags.bluekai.com" Happens with every new tab or website loaded. Clearing browser history definitely does not work. Seems a little too easy to get rid of a redirection malware...

I'm having the same issue. Clearing history and cookies does not help at all. Drop down box when visiting lots of sites says it can't verify the identity of stags.bluekai.com and that the certificate is invalid, so it is trying to redirect. Safari 9.1.3 on Mavericks. Just started recently.

It's not actually a pop-up, so this response is not helpful. Please provide a valid response. The issue just started on my computer as well, and it's a certificate issue caused by a redirect malware (according to the popular consensus).

I had the same issue for the last few days, and finally resolved it. I am also running Safari 9.1.3, and was experiencing the issue after visiting eBay. My first obvious approach was to reset Safari, but this did not resolve the issue. My second thought was to see if something snuck into my Chrome browser when I last used it, but nothing was there. Finally I found the best solution thus far, and is pretty simple. In Safari choose > Preferences, then click on the Privacy tab. Under the Privacy tab you will see "cookies and other website data", a few lines lower you will see "details...". Click on "details..." and go see if anything with "Bluekai" label appears in there, if so delete it. After you do that, quit Safari and relaunch.

One cannot upgrade directly from 10.9.5 to High Sierra. Also I don't understand how a simple browser redirect cannot be solved without upgrading to a new OS. It seems that "upgrade OS" is the standard Apple solution to every tech issue now. We really should be able to get a patch for known malware threats (since 2015) without full OS upgrades.

Furthermore, malware solutions notwithstanding, no OS upgrade has ever resulted in increased performance on any machine i've owned since 1986. I don't really understand why Apple insists on promoting upgrades. If my machine is running fine why do they care what OS I have? Unless they are trying to prompt me to buy new hardware...

Ok, so if this is simply a "certificate" issue then why do we need to upgrade to new OS? Can't Apple supply a fix to resolve a certificate issue? It seems however like Blueakai is trying to redirect to a site that cannot be certified. Either way, it doesn't seem like upgrading is the simplest fix anyone but Apple.

I have a 2011 MacBookPro that runs perfectly fine except that it keeps getting slower with every OS upgrade. It seems to me that running a browser should require very few resources yet every time I upgrade safari slows down.

Of course there is another fix, its called Firefox...

Yes please add me to this problem. I think Safari and Apple are losing the battle and becoming like PC where you just have to keep buying a new upgrade every two years because they do not dwell on correcting issues like this.

No longer a product that does not need third party malware protections etc.

I found a partial solution. Installing and using the privacy extension Disconnect, the drop down box stops appearing.

Certain websites consistently cause the drop down, for example a certain site that mainly concerns Mac rumors. When using Disconnect, it does show that it is blocking a connection to BlueKai.

Upgrading the OS is not an option for me due to the extensive software and hardware I am using. Clearing cookies does not fix this issue. This obviously just recently cropped up, and seemingly could just be fixed properly if BlueKai sorted out their certificate.

Yes, me too. It's only started happening in the past week, and seems to be more closely associated with eBay than anything else; however it's the prevalence of it on other random sites that's the most annoying thing.

I'm running Mavericks AND DO NOT WISH TO UPGRADE. (Do NOT suggest this as the 'only solution'). I prefer Safari to other browsers but will switch to Chrome or Firefox if this is not resolved. It's very very annoying.

A temporary fix is to Empty Caches which seems to work until I visit eBay.
