    I have MacBook Air 2018 8/256. I notice that when I go to in Safari it is very slow and causes it to be non-responsive for a few seconds and I even see the beachball sometimes. I don't see this as bad on my older MBP 2013. I installed an adblocker which helped a bit. I know CNN is a real dog of a site but this is real strange and I don't have this problem on any other site.

    Can anyone else try with their MBA 2018 and report back.

    i have the new MacBook Air 2018 (but with 16MB RAM).

    i dont sense any noticeable delay when accessing the CNN site.

    as with any site, it can depend on, and access time change, where you are trying to access it from as well.
    many ISP carriers actually cache some frequently used sites.

    i have also found that when i access sites while using VPN (in my case Express VPN), sites seem to load faster...(especially in Safari on iOS though).

    Just went to cnn and had my eyes burned by all that crap content. And yes, it loaded fast on my 2018 air. So there’s that

    I found that if I remove cookies for cnn it loads fast. As soon as I close the black bar at bottom about agreeing to their terms of service by clicking the X on right side then subsequent loads are slow. If I never close that window it’s fast all the time but that window will still appear at bottom. Can you test this.

    I just tried this on one of my MacBook Pros - a 2013 model and I can recreate it there also. If I load the first time there is no issue until I close the black bar at bottom of the window "By using this site, you agree to our updated Privacy Policy and our Terms of Use". After I close it with X on far right of black bar then if I reload the website and try scrolling right away I get no response and usually beach ball for about 10-15 seconds.

    If I remove cookies... Privacy, Manage website data and remove and then it works fine. I can reload page as often as I can... reload browser etc. as long as I don't ever close the black bar at bottom.

    Only in Safari. Firefox is fine.

    Not sure if Apple issue or CNN issue - who to blame at this time.

    You need to run the Ublock extension to block most of the ad popups. Some of these sites load literal tens of megabytes of crap into your browser.

    You can get like 3 videos auto playing. Its horrible. It would cause the water cooler fans on my 8700k desktop to spin up on some websites. Some of these websites are so bloated and loaded down its unreal.

    I am trying the 1Blocker extension found in App Store (I like the App on iOS so though I would give a try on MacOS). I was able to Hide that Page element. Another great feature is it syncs everything through iCloud so all my browsers have same settings after I did this on one Mac.

    Dumb question I know but will a 2018 TB MBP load web pages faster than the 2018 MBA?

    I have a late 2010 MacBook Air (yep, still works) and I am having this exact same issue. It has been occurring for the last month or two and seemingly just appeared out of nowhere one day. It only happens on the CNN website and it has been frustrating trying to find a solution...finally found this thread. I used your tip to remove CNN cookies and not X out the black bar and CNN works just fine now albeit with the black bar. Thanks for that workaround. Hopefully CNN or Apple will address this issue in later updates.

    So does this happen on Air only or MBP too?

    I can duplicate it on all three of my MacBook Pros - two 2013, a 2012, and my 2018 Air.

    Finally someone who can duplicate the problem!

    See my post above about 1Blocker... it allows to remove a screen element to get rid of that bar at bottom. It is not a free App, but is reasonable priced in App store. Maybe other adblockers work as well, didn't try.

    Some follow-up info that may help somebody...I was able to duplicate the issue on a Late 2013 MacBook Pro 13" and a 17" Early 2011 MacBook Pro, but the issue wasn't a huge nuisance like it was on my Late 2010 MacBook Air. In fact, I hadn't even realized it was an issue on those MacBook Pro computers until I found this thread and tested them. The issue was almost unnoticeable on the MacBook Pros, but the CNN site did freeze on those computers for a second or two and had a beachball for like a 1/2 second whereas on my MacBook Air it froze up for 10 seconds or more at times and had the beachball multiple times for a number of seconds every time I tried to scroll until the page was fully loaded and then would repeat when I clicked on a story link. All of these issues disappeared on all of the computers when I removed CNN cookies and left the TOS black bar in place. And again, this issue only happens with the CNN website as far as I can tell.

    I may try the 1Blocker in the future, but for now I can live with the black bar.

    Thanks again.

    I find it takes several reload attempts to get CNN to actually update the content.

    Interesting test... wondering if its the quad core vs dual? assume so and overall processing speeds? And maybe what else is open/stored on each system? Not an expert on these issues but seems like it could be potential explanation?

    Yes, if you have Activity Monitor loaded you can see the CPU % go very high.

    I can confirm that CPU % in Activity Monitor for CNN website went through the roof on my MacBook Air when issue was occurring and then was normalized with the workaround solution. Did not check Activity Monitor on the MacBook Pros but am guessing CPU % wasn't as high as MacBook Air. As far as open/stored programs on each system, it was pretty much apples to apples.
