Fix "kernel_task", a high CPU usage bugUsually, a popup warning isn’t the first sign that something is amiss. How to get rid of low memory notifications Internet Security and Track My Mac the current items are Antivirus and Adware Cleaner. And the Apple M1 chip keeps macOS secure while it’s running, just as iOS has protected iPhone for years.Feature-packed Mac security and tune-up app misses some basics.The first thing to note is this is a natural issue your Mac has a limited amount of RAM. In the most dire circumstances, your Mac will toss a warning at you: “your system has run out of application memory.”Don't despair – it's solvable. Thankfully, there is plenty you can do to resolve this problem and get your Mac operating smoothly again.Try free How to Fix Your System Application MemoryMac memory usage is often occupied by apps, even browsers like Safari or Google Chrome.Let’s discuss all these possibilities step by step. Websites may also be a culprit. This is especially true of older applications which haven’t been optimized for modern computer architecture.The most pertinent portion of the window is the bottom, where it shows you the total memory usage, and how it’s affecting your Mac.A better way to monitor your Mac’s memory use is with iStat Menus. Toggle to the Memory pane in the Activity Monitor windowAs you see in the above screenshot, Activity Monitor shows you all of your processes, sub-processes, and how much memory each is taking up. Open Activity Monitor from your list of applications. You can do this in Mac’s control center, via the Finder in your Dock, or by pressing ⌘ + Space and typing Activity Monitor in the Spotlight.
![]() For Activity Monitor, you'd make sure to highlight the CPU section of the window. How to check CPU usage on MacChecking CPU use on your Mac is similar to the steps above for checking memory use. A simple click on the menu bar icon surfaces a drop-down menu of how your Mac is performing at the time, and hovering over each graphic brings up a larger menu to inspect. Only the items you’re monitoring will have an icon in your menu bar. Memory Cleaner App Virus How To Clear MemoryNot only does it show the exact CPU percentage and battery impact each process is taking from your Mac, it lets you create simple rules to prevent certain processes from hogging too much CPU.To tame any app, just click on it in App Tamer (located in the menu bar), select “Slow down this app if it uses more than” and specify the exact CPU percentage.Knowing how to clear memory on Mac is important, especially if you have a Mac with limited resources. So you need to do something about it.App Tamer is perhaps the most powerful smart CPU manager out there. That’s why you can have applications not responding. Processors differ in power (expressed in GHz) and efficiency (generally, newer processors are more efficient).For example, a 9th Generation 2.2 GHz Dual-Core Intel Core i7 processor means that it has two i7 chips, each of which is able to process data at up to 2.2 GHz, and its the 9th iteration of that processor overall.However, regardless of the power of your processor, if you throw too many tasks at it, it will start to slow because it’s trying to process too much information at once (try opening 100 Google Chrome tabs), creating a bottleneck. Activating that will add a CPU and GPU monitor to your Mac menu bar, which has the same interactivity as the memory icon and menu shown above.But what creates CPU-hogging problems overall and how do they lead to slow Mac performance?Every Mac has a processor which handles the computing of any task, from opening an app to editing photos. ![]() Another hardware issue, including a worn out batter A failed or disconnected temperature sensor If none of this work and kernel_task is still absorbing a high percentage of your CPU, then one or more of the following could be the cause: Unfortunately, one of the potential downsides is a Mac can overheat to such an extent that internal systems are damaged, sometimes irreparably.Working through the following steps in this article is one way to avoid similar problems. One of the functions of kernel_task is to help manage CPU temperature you may find that your Mac fan is loud and always on, even if the device isn't hot to the touch.That's because kernel_task usually performs this way when one or more applications are trying to use too much CPU. Under 'New Finder windows show', click the dropdown menu and choose any option except All My Files Click on the Finder icon in the Dock and click on the Finder menu, then select Preferences If iStat Menus or Activity Monitor has highlighted Finder as using hundreds of MBs of RAM, there is an easy solution: change the default display for a new Finder window so it doesn't show All My Files: Reduce memory usage in FinderOne common culprit for RAM issues is Finder, your Mac's file manager. Keep in mind you won't lose any data in this process. It's essentially a hard reset for your Mac, and should help your RAM and other hardware components start from scratch. I aint scared of you a tribute to bernie mac torrent pirate bayScroll to the bottom of the page and select Advanced Select End Process at the bottom right of the windowHere's another way to reduce Chrome's use of your Mac's memory: Select a Chrome process you'd like to kill On the right side of the Chrome window, select the three-dot menu Click RelaunchFinder will now relaunch with new windows opening at the option you selected in step two.Chrome is a popular browser, but it's a resource hog! Chrome uses a GPU Process as standard, which means it speeds up the loading of web pages, which can be great except at times when your computer is struggling with insufficient RAM. It's really that simple!Login items, browser extensions, and preference panes, such as Flash, are another common source of memory usage. All you have to do is view the list of extensions, select the ones you no longer want, and remove them. You can manage each one manually or use a tool such as CleanMyMac X to identify and delete them.In the CleanMyMac X app is a section titled Extensions, which lists each extension you have for your browser or browsers. You can also remove unused or unwanted Chrome extensions to help it use less resources on your Mac.In every browser you use regularly, there are always going to be extensions and popups that take up space and use RAM.
