However, it gives you more control and can be more aggressive. It more or less does the same thing as the macOS built-in App Nap function and throttles inactive or background apps. Undervolting can lead to unstable operation, while disabling TurboBoost usually creates no issues. Basically the same as the above, but it can undervolt your CPU in addition. The result is a slower Mac, especially in single-threaded applications, but also some power saving and less noise. This app disables the Intel TurboBoost functionality, meaning it won't overclock the CPU above the base frequency anymore. In addition to that you can try the following things (some of these apps may not work on your specific MacBook Pro model): It keeps my MacBook Pro much more quiet and gives me quite some extra battery time. Probably you will not like this solution, but ever since I resorted to using Safari almost exclusively. The use of multiple CPUs heats the CPU much quicker. When Firefox released their cool new multi-threaded version, I experienced exactly the same problem as you. Now, it is sits at 40˚C with the fan running on high to prevent it increasing.Īm I missing controls or options to have less heat from the CPU of this era MacBook Pro?
I believe it has something to do with videos in general that are being servedĪt the moment, I have had to use an app called MacsFanControl so my fan stops the CPU and computer from overheating as it used to get to around 50˚C.
I've tried other web browsing apps and they net similar results as Chrome. turning off JavaScript (which, of course, just stopped the page from loading in - very power efficient and cool, but not the trade off I had hoped to accomplish).turning off Unsandboxed plug-in access to "not allow any site to use a plug-in to access computer".Here are some things I’ve attempted to control / solve this: I own an up-to-date MacBook Pro (13-inch, Mid 2012) so it could be a result of an old system but only Chrome and YouTube (or just videos) are causing this issue. I don't understand the math behind it but its evident in the screenshots I took.
On YouTube, one of these can spike up to using %82, with a second using %22. Whenever I am browsing the web, there are usually ten seperate entries of Google Chrome Helper in Activity Monitor, each individually using around %0.5 of my CPU. According to Activity Monitor, Google Chrome Helper is the culprit. For a long time now, my Macbook has been overheating and hogging my CPU.
