Webpage using significant energy / memory on Mac

If the above doesn't work, Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items. Quit/reopen Safari and test. You can also try try Safari/Clear History…. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site. Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library/Caches/com.apple.Safari/Cache.db and move it to the trash.

Go to Safari Preferences/Extensions and turn all extensions off. Test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.

Etrecheck – System Information

I tried Chrome and I had the same issue. I have some extensions (Norton and Grammarly) which when are disabled the use of RAM memory reduce significantly. In my opinion, Apple should work to understand why extensions are causing this problem. Just for the registry, I always had extensions and I never had this problem before.

leroydouglas Thanks for your response, I think you have found the solution. I have a MacBook Pro early 2011 with an i5 processor, 16GB RAM, 500GB HDD w/appx 150GB free and was having this issue when running FB. I tried all the other solutions offered and none helped.

I opened "Develop", "Experimental Features" and unticked "Cache API" and my problem seems to have gone away. No more message, slowdowns, spinning wheel or videos not displaying properly. I planned on turning them off one at a time to see if one of them was the cause and if I could isolate it. Seems I don't have to do any more.

Again, I thank you.

I did not have time time yet to do this very thing ie "turning them off one at a time."

We will wait and see if there is corroboration across the board before we jump up and down with joy 😉

Thanks for the feedback Davidj92.

I don' think shutting it down is sufficient I got this message and closing it only solves this temporarily

the truth is you may need more Ram Memory it's very easy to fix if your under warranty Mac Won't help you exactly

but my machine is out of warranty it's a @ 2010 Macbook, 7,1 I can upgrade it I added 16GB Ram Memory from 4 which for risk of being sued Mac can't advertise it but it does hold it and no more messages

and I'm flying in speed Running High Sierra think about it my mac is 8 years old I can get at least two more years out of

and I'm editing videos which takes alot of space I upgraded my hard drive and I have 4 Terrabtye External

all like new Macs last a Long Time. Very Long time and the answer is if you can add more ram end of problem permanently learn how to change your ram on Youtube it's very easy and get the right screwdrivers , very easy just unplug any plugs or batteries while doing so any electricity connected Must be Taken off so as to not damage any electric current or fry the motherboard you are fine, good luck if you need anything Also there is a Hard drive cloner in case you ever need to clone your hard drive into a new one . you can buy your parts used or new online and all is well there is so much you can do with your Mac to upgrade it it's incredible .

Hope this helps you and all in the Future Mac Help

Yes, it happens only when I watch videos. However, others have stated it happens on some other websites.

I stream video almost daily so I noticed right away. For me, it started after a system update. I filed a ticket but nothing ever became of it.

It was annoying enough for me to try a different machine (I have two macbooks, they both have 16GB RAM), same problem. My solution was using a different browser. This doesn't happen in Chrome for me. That was the easiest thing to do.

Safari/Preferences/Extensions and remove the checkmark from all extensions. Test. If it fixes the problem, add the checkmark back 1 by 1 until you find the extension that is causing the problem.

Try the new Security Update 2018-001. It should be available as an update in App store. I just updated and the error seems to have gone away.

Try setting up another admin user account to see if the same problem continues. Also try the Safe Mode.

also Sierra

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.

Thats because there is nothing wrong with your computer or safari. The webpage is simply using alot of processing power. I get this message specifically on some sites that have very large & live comment sections. All the message means is that because the browser (that page specifically) is using so much processing power, the mac may be slower with other tasks.

Eric needs to calm down with all this stuff he's having you do because it's not going to "fix" this situation. Getting a faster mac would or just ignoring the message.

The error is showing because you are viewing a Javascript heavy site that is consuming a significant amount of energy.

I get the message when I have facebook open. I have a habit of leaving it open and it wastes a lot of electricity. So that subtle error reminds me to close the window when I'm done. Hopefully facebook will rein their site in a little.

I don't know of a way to disable the message except to avoid the websites that trigger them.

Here's an answer that actually will work. Use a browser other than Safari. Full stop. Opera and Chrome will both give you far superior performance.

Did you try disabling the Safari extensions?
