on several web sites that i use routinely, ads keep popping up for "mackeeper".  this is not unusual, but...


whenever they pop up, my mac slows down, not just noticeably, but to the point of becoming unresponsive.  or so it would appear.  except that i can switch to other applications with no problems AND NO SLOWDOWN.  it's only safari that's playing dead.  and all i can see is their annoying ad saying: "is your mac too slow?"


can anyone confirm whether these mackeeper ads are *deliberately* running scripts that bog safari down?


because if they are, this would be a highly disreputable tactic for any legitimate business to do, in the name of "advertising".

    MacKeeper is something you want to avoid like the plague...


    Try this..   open the Finder. From the Finder menu bar top of your screen click Go > Go to Folder


    Type this exactly as you see it here:  ~/Library/Safari


    Click Go the move these files from the Safari folder to the Trash.




    Downloads. plist




    Quit then relaunch Safari. From the Safari menu bar click Safari > Empty Cache


    See if that made a difference...


    If not, check out the User Tip by Klaus1 regarding MacKeeper here.

    What? MacKeeper and Chrome in bed together? Perhaps that is why I have seen so many people using Chrome lately. I would like to think that these companies would need a more sophisticate marketing strategy than an ad that looks like a button, but perhaps I'm wrong. I am one of the few people to halfway bother to defend MacKeeper. Maybe I should re-think that.


    both of them seem to be embedded in the page, and have MUCH larger clickable areas than just their buttons.  (and the mackeeper ad is actually designed to look like the rest of the speedtest page, to lure you into clicking on it instead.)


    the bad part is being hijacked for 2 or 3 MINUTES before i can get back to the actual content of the page, which happens to be useful.  (force-quitting safari makes me feel better, but then i still have to go back to the site and get annoyed all over again.)


    While I certainly see those ads, I don't notice any performance problems. Perhaps your Flash is out of date. Update Flash and then install ClickToFlash. That will hide those Flash-based ads. Just click on the content area to enable the Flash for the speed tester. Personally, I prefer the Speakeasy Speed tester - no MacKeeper or Google ads.

    Just a little hyperbole between friends


    it is at the highest version supported for my  hardware and operating system, according to's flash support pages.  and i don't have these problems on any other site that uses flash.


    And what might that be? According to your profile, you are running some older hardware and software. I have no doubt that Flash is going to perform much worse on old hardware than new. It is only recently that Flash even used graphics hardware acceleration on the Mac. Everything was done on the CPU. I prefered to watch videos on my iPad instead of my old MacBook. The iPad can only do HTML5 video but the MacBook would do flash. I had difficulty hearing the audio because the fans were so loud.


    Flash definitely uses the GPU now. In Chrome, it will exhaust video memory and cause kernel panics.
