Tell HN: MacBook CPU Usage and Brave
When the world of atoms and the world of bits collide:
My Mac was getting uncomfortably hot, and naturally I figured the battery was getting old or something. I usually have it on my lap, so this was a problem.
When I did a search, some page said "look at the Activity Monitor and see what's using the CPU."
I was dubious, but I thought, "OK, sure" and brought it up. There were two Brave windows, each with many, many tabs open, and they were both over 100% of the CPU. I wouldn't have thought that was even possible.
I killed them both, just to see, and now the thing is much cooler. I can keep it on my lap comfortably.

- behnamoh 3y agoInstall an extension that freezes unused tabs so they don’t use up your memory and stop playing things in the background so they won’t utilize your cpu.
- AlbertCory 3y agoThanks. Apparently Brave can use Chrome extensions. The more you know.
- weikju 3y agoThis is a feature built in to Brave now, perhaps even all chromium based browsers. There’s the memory saver and the energy saver
