I can't think of anything that I've changed on the machine to have caused this. It worked fine for the longest time. I tried clearing out temp browser files, reinstalling the silverlight plugin, rebooting, etc. and nothing helps.

Video by nature is CPU intensive, that being the case it's not surprise Netflix is using a lot of CPU. As for making your system unusable, things I'd look at are the amount of RAM in the computer. You didn't mention which iMac you have but one thing to look at is is open Activity Monitor - System Memory and check the amount of Free RAM. As a general rule of thumb if it's 500MB or less your system could probably use a RAM upgrade. Do this when running Netflix or when you see a system slow-down.

I have the same problem with the exception that I'm not looking at a video, I am simply watching the Netflix web site, and I'm using Linux Mint 17.1 . I've watched the top process (system monitor) and loaded the Netflix web page and the web content process goes through the roof (over 100% cpu usage). When I kill the web content process, only the Netflix tab (in Mozilla Firefox) dies and all other operations do not appear to be affected.

This behaviour has not always occurred and appears to have just recently started to happen, within the last few days. This behaviour makes my computer virtually unusable and until I am able to stop it from happening I will not be starting the Netflix web page which is a nuisance because I use it to look for programs that I would like to watch on my smart TV.

Thank you for the reply. I understand the video is CPU intense, but my point was that something has recently changed because just weeks ago I was able to do the same activities (netflix + other apps running) without the maxed out CPU.

Were you running Netflix when you had 1.68GB free? To be honest 4GB isn't that much RAM these days, so you may want to still consider upgrading it. It's inexpensive if you buy from reputable sources such as www.macsales.com (OWC) or Crucial. Do not buy RAM directly from Apple!

You can also do some other resets but I don't know if they will affect your situation. You can reset both the SMC and PRAM, it not a bad idea to each reset 2x. Please follow these instructions closely:

I've tried running netflix on internet explorer running on a virtual machine inside VMware fusion. the free memory goes down to 100megs (definitely need to do that memory upgrade) but even running it that way the osx apps are more responsive and it's using less CPU than if I ran netflix inside safari. Something isn't working right.

Here's the link to what fixed my problem immediately. Please note: my problem was resolved following just the three steps pasted below. The original link has additional steps that may be necessary, although I did not employ them, and my problem of 100% CPU USAGE is gone!!! Thank God!

I haven't tried Bethesdas steps yet, but I figured I would mention that within the past couple of days Netflix has been doing the same thing to me. I don't have an Apple computer, but this is the only post anywhere I found about this.

So usually when watching Netflix I'm only running about 40% cpu (I believe), but now suddenly it's running in the high 80's up to 100. The only reason I noticed is because suddenly now when I go to a different tab, the video stops and starts buffering, but can't buffer all the way up until going back to the Netflix tab. This is really annoying, by the way. Also, now about 50% of the time when I open fullscreen, everything but the audio stops, so I have to exit fullscreen and then go back in... Also the video is starting to get a bit choppy which is what prompted me to start looking for an answer.

I have noticed this as well. The Silverlight plug-in didn't used to take up all the CPU usage. Oddly, if I go to full screen mode (I have dual monitors) I can see the CPU usage drops to about 50% exactly the opposite of what you would think should happen (More pixels are being pused to the screen so it should run slower) I think this is an error in the way the Silverlight plugin handles video on the Apple OS.

If you use Airplay or Screen Mirroring
Airplay and Screen Mirroring are no longer supported by Netflix.
To use your iPhone or iPad to watch Netflix on a TV, use a supported connection.
Also it has to be an 'ad free; type of account:

True, but in this case legal won that battle. Plus it's easier. We use Swank for licensing the physical media playback anyways so we just tacked on the streaming service and we have our butts covered.

@ger Sorry if I am missing something here but you would assign license / push out the managed app via MDM / Jamf to the apple tv device, it is the same as the ipadOS app.
Instead of airplay you are now playing the content directly via the Netflix app installed on the Apple TV.

As unhelpful as it sounds, anyone that has a netflix account and wants to display content, will need to log into the Apple TV app then navigate the interface to play.
Airplay (I imagine) has less ways of ramming adverts down your throat so the main streaming apps cut off support as opposed streaming content directly in app.

Ok great. Yes either, just depends if they still have the remote but sign-in on screen.

* Yes we do, either by managed iPad or unmanaged iOS device.
* Yes it sure is, send out a profile to your Apple TV's and allow list either;

- iOS devices that are allowed to use Apple TV Remote app with this ATV
- Apple TV's that are allowed to be controlled with iOS / Apple TV Remote app

You can browse individual managed devices to select and it will populate: name and mac address. Otherwise, set to all allowed.

I have to use JAMF School, and it seems to be different to your PRO version.
In ATV Profile under tvOS payload / Apple TV Remote / I may allow all devices with Apple TV Remote App to control ATVs. Or I may enter the MAC-Address of allowed devices.

As I do not want students to use the Netflix App and as I do not want them to control the ATVs with their iPad, I did not select the ALL devices option.
For testing purpose I entered the MAC of my iPhone, WLAN and Bluetooth. ( do I have to enter it with or without : , like AA:BB:CC:DD:EE:FF or like AABBCCDDEEFF )
But I could not connect to the ATV.
I do not have your "Controlled Apple TV Devices" option, but I may assign a device group containing the ATVs to the profile.

Unfortunately my JAMF School WebUserInterface is in german and I can not find any setting to switch to english, Windows and Browser are set to english. My account information is even shown in english. :-(

Strange about not seeing the settings, maybe just confirm there isn't any filtering toggled on when creating the profile as those two settings are meant for different models and will disappear if filtered with the other device. Good luck!
