Webpage using significant energy / memory on Mac

I have done everything asked to get rid of this and nothing has worked. It's frustrating when the pop up occurs and even more so when the page automatically refreshes because of this.

See this thread: Re: Safari message stating "this webpage is using significant energy"

Some things are out of your control. I see this as a non-issue. Safari is working in your behalf to keep everything running smooth as possible in it's rendering engine.

My only suggestion is you could try a different browser and see if it renders the page any more efficiently.

Seems to be only with Safari, not with Firefox. Hoping to see some response from someone who has come up with some type of reasonable explanation.

Re: Safari message stating "this webpage is using significant energy"

same here, i only got this pro after i update my mac this afternoon. I'm sure it's the updated system caused this kind of pro, and there should be more people facing the same issue. Hopping some guys will find some way to solve it, it's very annoying.

It is the new Safari updated with 10.13.x-10.13.4, everything is working as it should. I do not notice any slow down or disruption to Safari in all honesty, besides the pop-up banner. This may be a clue that Safari is working as efficiently on your behalf to keep things running smooth behind the scenes.

Ignore the warning if you wish, or excuse it by the x. There is absolutely no user harm either way. I suspect if (like before the new Safari) you did not get the warning, you would be non-the-wiser.

Just because Safari is "made for Mac," it has no control over half baked code a website is running. (Maybe that would be the better warning message.) A resource intense interface. As you can imagine CNN, Facebook run some realtime API's that not all rendering engines interpret in same way. This is by design or there would be no difference or need for different browsers. Think of it this way that warning message keeps people employed. 😉

If this troublesome warning message popped up on every other website—then yes Safari has a problem. It simply is not case, from your post, other post on ASC, or my own user experience.

By all means send Apple Feedback http://www.apple.com/feedback/

Please note I am not an apologist for the Safari.app I just see it as a non-issue. Surely there are bigger fish to fry.

Those of us here complaining obviously don't consider it a non-issue, and telling people who are bothered by it that you disagree does not provide any help in resolving the issue.

All standards-compliant rendering engines have no problem with Facebook or MSN, and though I haven't worked on those sites myself I'd venture an educated guess as a web developer that neither of them use any "half-baked" code. I know Facebook in particular does enormous QA and staged rollouts of new features to catch any problems early.

This is a Safari issue. The solution is to use a different browser.

I have the same issue on various web pages. Have sent feedback as it is an annoying and unwanted issue if you have the same issue send feedback. Link on above post and annoy the bejeebers out of them.

I have this issue as well. Recently upgraded to iOS 10.13.4 High Sierra, running Safari 11.1. The message appears only (so far) when I am playing a Facebook game, and also the game slows significantly, becoming jerky and unplayable. No other applications are open at the time. Recommended fixes have not worked.

It is not your issue to be resolved. Frustrating maybe, but out of your hands.

The best you can do is try a different browser that using a different rendering engine than Safari (which uses Webkit.)

An Alternative for ex. Firefox use Gecko.

Apple Feedback http://www.apple.com/feedback/

Hmmm, well I hope you are able to get resolution. My error message has gone away though. The only things I did were clearing the cache on Safari, installing the security update that apparently Canada gets a week later than everyone else:( and, since I was only getting the error on msn.com, I contacted them through their feedback button to let them know of the issue

OMG! I thought I was losing my mind but now I see a lot of others are having this problem. And it's not just an annoying banner (the message flips between using too much energy and too much memory). My performance was impacted. Spinning wheels, slow response times and unexpected reboots. Ridiculous. It started on just my msn account but soon escalated to other webpages and even when I only had one Microsoft app open.

I've tried all the suggestions noted. Specifically with the help of 3 calls to Apple support and an actual in store Genius Bar visit. I even bought a new Macbook Pro about a month ago thinking this would resolve it but after using for 45 minutes the same problems popped up.

Too much money for Apple to not fix this. The irony of not be able to use Safari on my MAC is crazy but I have reverted to Chrome. Like most people, my laptop is my livelihood (independent consultant) so this needs to work. Even if it is vintage (circa 2011). :-)

With the many glitches in Safari, including this one, like videos that don't work, etc, the perfect solution is to IGNORE Safari and make another browser your default. Why should we constantly be obliged to go through IT gibberish hoops, especially when most people are NOT IT, just to have a browser that doesn't work without any problems?

Agree to your comments, but can you help us out and offer other alternatives than just saying ignore Safari? What browser are you using? Does it work well for you?

I have been trying out Firefox, which I used years ago, as an alternative to Safari and it's not much better. Slow responsiveness, jerky cursor issues and one crash during game play. Other options I've found and may try are Chrome, Atomic Browser, Dolphin Browser, and iCab.

If anyone has changed browsers and likes what they are using, please let us all know!

I switched to Chrome as my default browser a few of weeks ago and that's been working really well for me. But I will say when listening to my iTunes on my laptop it did auto-reboot on me with no warning about 3 days ago. I may try one last trip to Apple but not sure I'm going get a different result.
