Additional Information:


could you disable all extension then restart you computer and see if it work fine or not

if it work fine then the issue with one of your extension try to renable them one by one till you get the one that cause the issue

I can’t help with your problem but 102% isn’t unusual. Your Mac has multiple cores in its processor and each is capable of 100% capacity so if you have four cores, the maximum capacity would be 400%.

thanks for explaining that @okulo as i never had one :wink:
never thought that mac use that way to calculate the processor usage

in linux and windows it each core = 100 / number of cores so in case of 4 core each core will be 25%

thanks again and have a nice day :slight_smile:

100% for a multi-core Mac, if the only running app is Brave, is definitely unusual. I get 5% or less.

My impression is that Chromium and Brave are not optimized for Apple M1 and/or macOS.

@CHMIELIX out of curiosity, do you have Intel or M1?

INTEL i7 from 2018. Actually the Mac is the highest configuration from that year.

I have only 3 extensions. i did what u said and no change, but… seems like its ok when I dont have too many tabs open… I had like 10 or so of which 3 or 4 were different exchanges refreshing all the time, plus some video playing etc so maybe this was the issue. thanks for help.

My point was to address the apparent surprise that CPU could exceed 100% which was clearly confirmed by CHMIELIX’s reply.

That said, I have two quad core Macs and I have frequently seen Brave use >100% and I only have to open a YouTube video to reach 125% without even being full screen.


That’s because Chromium and its descendants are not optimized for macOS. Things may be even worse for M1, since it’s newer.
Sad truth: Safari is much faster.

yeah but safari workflow is the worst. anyway thanks for all the advices. peace
