I read that mess, Dezmond! I've been using Apple products since the 1980s. I've always been pleased. I can't tell you how many Apple computers I've owned, so Apple needs to fix this QtKitServer Safari Web Content problem in Mavericks. This is not Apple-like at all. I hope they have a 10.9.1 update for Mavericks soon. Other than this problem, I love Mavericks. It runs fine for me.

Every time I quit Safari, the QTKitServer disappears from Activity Monitor under Mavericks. I don't get the issues with any other programs. I thought about trying other browsers and closing Safari. I would like to see if the issue reappears at that point. If it doesn't, then I'll know it's all tied in with Safari. I thing this new Safari 7 might just be buggy, ya know?

This macbook is doing my head right in... Normal usage such as selecting an option via the Menu Bar of an application takes a second/two to appear, which doesn't sound major but it is when it never used to happen before... A bit off topic but still I paid a lot of £ and did not expect such things to occur. 1 year old Mac, plenty of HDD space.

Mac4Life2012, don't blame Apple so much for the fresh bugs with Mavericks. This is the first time I have installed a new version of OS X on the first day it was released. Even the first releases of previous OS X versions have had issues, and Apple eventually patched up the bugs and stuff. If you are having any other kinds of problems, I would suggest waiting for the OS X Mavericks 10.9.1 update. You can always use Time Machine to restore to OS X Mountain Lion 10.8.5. I mean, if the issues are too bad for you, you could always do that. However, my Macbook Pro is two years old, and it runs just fine on Mavericks. The only thing that I find wrong is this QTKitServer issue in Activity Monitor, but it doesn't use up lots of resources or anything when the process stops responding. Personally, I don't like the new iMovie though, and I hate Chrome.

Hopefully this bug will be fixed soon. It's a bummer, but I'm glad to know that my machine isn't defective. I've been tweeking out contemplating the cause: browser plugins, software compatibility issues, a potential virus.... Pinwheel flashes will drive a man crazy.

Well, you don't have to worry about a virus on the Mac. There aren't any viruses for the Mac, and most malware or other trojan horses won't run on a Mac unless you willingly install them by entering your admin name and password. These Mavericks bugs should be fixed sooner or later. Plenty of people have this QTKitServer not responding problem, so Apple knows about it. I even called Apple myself, and the engineers are looking into it as we speak. A Senior Advisor from Apple is suppose to call me when the engineers have the answer, because I have an open case with them.

I just like to add that since I have been deleting QTKitServer Safari Web Content (unresponsive activity in red) from the Activity Monitor, my MacBook Pro early 2008 4gb RAM seems to running better with Mavericks. When I updated to Mavericks from Snow Leopard I did not do a clean install. However, having read posts about Mavericks problems I do not think it made a difference. I hope this situation continues until Apple fixes the bug.
I would suggest that anyone having problems with Mavericks look into this bug on their computer; as a possible culprit.

On another note: It seems as if it was a good move to carefully listen to the fan (having a MBP). Once that goes off like a turbo, this is a good sign that there are a couple of QTKitServer in red that wait to be terminated.
Once terminated, it seems as if the fan activity/heat production winds down.
Heat is actually a real problem with my MBP as it already killed 2(!) Logiboards..
I'm considering moving to FireFox altogether as those faulty processes say: Safari. Might fix the issue.

You are so right. I did not understand heat activity situation I was having with my computer until I discovered this post. Fortunately I do no think I suffered any damage.
Question: Is this a Safari problem or Mavericks problem?
BTW: I think Firefox uses more CPU.

Update: I have not had a crash or flickering screen problem until I tried out of curiosity to open Quick Time. Once I open it my screen started flickering again and I needed to shut down and restart to resolve problem. FYI: My first flickering problem also appeard when I was using Quick Time for the first time with Mavericks installed.
Ia there a problem with Quick Time and Mavericks?

This occurred when updating an Aperture library with no browser open and was associated with excruciating slowness in updating an Aperture vault; taking hours instead of a few minutes. So we have learned the bug is not limited to Safari, not limited to method of Mavericks installation, and occurs on MB Pro, Mac mini, and MacPro.

Hmmm. I was thinking it was most likely a bug in Mavericks. Glad you let us know that. I suppose we'll have to wait and see if Apple fixes the QTKitServer bug with the next Mavericks update (10.9.1). I haven't really suffered any serious issues from the QTKitServer not responding, but it shouldn't be doing that in Activity monitor. Being the perfectionist I am, I don't like a red, not responding process in Activity monitor at all. Oh, well, I guess that proves that it's not specifically related to Safari 7. That's good to know.
