Webpage using significant energy / memory on Mac

Hello,

I'm continuing to get this alert at the top of Safari.

This webpage is using significant energy. Closing it may improve the responsiveness of your Mac.

How do I get rid of it?

I'm running macOS High Sierra on my MacBook Air. Version 10.13.4


Thank you,

Tim ***

Same here. This began fairly recently. I have no Safari extensions, I have no apps that didn't come from the App Store. i have no keepers or cleaners and my etrecheck showed that my mac performance was excellent. I usually get this message when I'm on CNN or CBS and there is a video accompanying the news story. I've never had this before. I've been thinking I was hacked but obviously others here are experiencing this too.

For trying another admin user account, the intent is to see if it is specific to one account or a system wide problem. This account can be deleted later. If it is a system wide problem, one answer might be to reinstall the OS.


The Safe Mode will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem.

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.

May 2, 2018 6:30 AM in response to tekey

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

May 3, 2018 3:23 PM in response to tekey

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). :-)
