Control CPU, memory, and whatnot with iStat Menus app.
When your Mac slows down or starts behaving erratically, chances are it's because an application that's running, perhaps in the background, is misbehaving. And if it's not an application that's causing the problem, it will almost certainly be a process associated with macOS or an ancillary service.
Solving this problem is usually as simple as killing the process, but in order to do that you need to identify which one.Here's a comprehensive guide on how to view and kill processes on your Mac.

How to show which processes consume a lot of memory
The easiest way to view all active processes running on your Mac is to launch Activity Monitor from your Applications folder. In the default CPU tab, you can see how much processing power every process takes, ranked by the most consuming. And if you switch to the Memory tab, you will see the same list ranked by the amount of used up RAM.
For more immediate and elaborate information on how your computer resources are consumed, use iStat Menus, which handily lives in your menu bar and, in its MEM table, shows you applications and processes that are consuming more than their fair share of RAM in real time.

How to prevent problematic processes
You can pretty much avoid issues altogether by being a little bit proactive in hunting down the common culprits. Here, iStat Menus will help you identify which applications or processes are consuming finite resources, such as CPU and RAM.
Then, you can use CleanMyMac maintenance routines that, when run regularly, will keep you Mac running smoothly. Here's how to do that:
Run other tasks, as necessary. If you're having problems with Mail, repeat step 3, but this time click the checkbox next to Speed Up Mail. Likewise, if Spotlight is running slowly, run the Reindex Spotlight task.
How to kill a background process
To kill a background process, use Activity Monitor. While the steps are the same as described in the 'How to kill a running process using Activity Monitor' section above, the key difference is that background processes often have obscure names that don't clearly describe what they do.
Be careful when killing a background process and, if not sure, leave it alone or search online for its exact role in your system. Otherwise, you might risk causes problems for your macOS. Generally, background processes don't tend to consume significant RAM or CPU cycles, so if you spot one that does, it has probably got into trouble. Kill it using the X in the Activity Monitor toolbar.
How to easily remove startup items
One common cause of Macs running slowly or having problems is items that launch automatically at startup. These could be helper apps for something like iTunes or just complete apps in their own right. They are also frequently apps you once used but no longer need.

How to Force Quit an application that's not responding
If you see the dreaded spinning beachball, or an app just won't do anything, you should force quit it.
There are several ways to force quit an unresponsive application:
Fix crashing apps with Spindump
While Force Quit will fix the problem, it’s a temporary solution. If you’re determined to identify the source of crashing apps and prevent them from happening, use Spindump on Mac. It’s a hang reporting tool that alerts you about the crash and helps share the details with the app developer.
Whenever the app crashes, it will trigger Spindump and send the information to Apple or the app developer. Not only does it help you understand what just happened, but it also helps the developer track the conditions of app misbehavior — and fix it accordingly. A win-win.
How to create a Spindump file on Mac
Reset a problematic app
There's one more thing you can try if an app keeps running slowly or crashing – reset it. Thanks to CleanMyMac, resetting an app is easy. Here's what you need to do:
If resetting the app doesn't work, the final resort should be to uninstall the app completely and reinstall it. To do that, click Complete Uninstallation in the same menu instead of Application Reset.
As you can see there are lots of different ways and apps that help you view and kill processes in macOS. iStat Menus is a great way to passively monitor which processes are causing problems, so you can launch Activity Monitor and quit them. And running CleanMyMac's maintenance scripts regularly prevents problems occurring in the first place. Best of all, all these apps are available to try for free on Setapp, along with over 200 high-quality macOS apps. So check your Mac for problematic processes now and see what you find.

Big Sur is a terrific update to macOS. But, like any new operating system, it’s not without its problems. For example, Catalina caused many problems, some of them serious, for many users. Thankfully, for most of us, the problems we’re likely to run into are much less serious and usually have a straightforward fix. In this article, we’ll examine some of the most common macOS Big Sur issues and fixes.
11 macOS Big Sur issues
In this blog post, we’re covering the issues that may occur during Big Sur installation and after you've upgraded your Mac. If you’re interested in resolving a particular issue, just go through this list and choose the one that relates to you:
1. macOS Big Sur won’t download
If you see a message while you’re downloading Big Sur that says, 'macOS Big Sur download has failed,' there could be a number of reasons. Here’s what to do when macOS Big Sur won’t download.
Have you got enough free space?
It can be difficult to decide what files to remove and what to keep. However, there are many files on your Mac that take up several gigabytes of space that you probably don’t even realize are there. These include temporary files, cache, language support files, and many others. CleanMyMac X can identify those files and allow you to remove them with a couple of clicks, potentially clawing back gigabytes of space.
CleanMyMac X has a free version you can try, and this app is notarized by Apple.

2. macOS Big Sur won’t install
If the download completes successfully, but macOS Big Sur won’t install, there are a few things you should try.
Also, double-check that your Mac is compatible. The list of Macs on which Big Sur is supported is below:
If you see the 'Installation failed: an error occurred while installing the selected updates' message, the first thing you should do is restart your Mac. If this doesn't help, the problem is probably on Apple's side. Wait for some time, and try installing the macOS Big Sur again.
3. macOS Big Sur freezing
Your Mac freezes after the upgrade? Your apps and programs can actually be the reason why macOS Big Sur is freezing.
To quit the unresponsive app, press Command-Option-Esc. This will initiate a Force Quit menu. Click the app that makes your macOS freeze (it will usually have not responding status) and press Force Quit.

4. macOS Big Sur setup fails
This error occurs after your Mac has updated to Big Sur, but during the setup process. Here’s what to do when macOS Big Sur setup fails:
5. macOS Big Sur won’t boot
If you’ve successfully installed macOS Big Sur, congratulations! You’ve cleared the biggest hurdle. However, you may still run into problems, one of which might be that Big Sur fails to boot. Installing mac apps directly to external drive. Here’s a checklist to follow if macOS Big Sur won’t boot.
6. macOS Big Sur is running slow
This is perhaps the most common problem you’re likely to run into with Big Sur. It’s logical to assume that a new version of macOS should run faster than previous versions. And in some cases, that’s true. For example, Safari tends to speed up with every release. But new versions of the OS also put more pressure on system resources.
So, if you have a Mac that’s a few years old, you are likely to encounter that the macOS Big Sur is running slow. There is plenty you can do to mitigate that, though.
Things that can slow down your Big Sur experience:
If you have a free minute to investigate, you can once again use CleanMyMac X to disable login items that can considerably slow down your Mac at start-up and while it's running.
Now, all those apps won't be opening as you start up your Mac.
Check your Activity Monitor
Activity Monitor will tell you which processes are consuming more than their fair share of CPU cycles and RAM. Once you’ve identified those, you can decide if you really need those apps. If not, you can get rid of them, and that should speed up your Mac. Likewise, there may be login items you have long forgotten about that are running in the background, slowing down your Mac.
If your Mac speeds up, you know it was that process that was causing the problem. If it’s associated with an app or login item, you can decide whether to uninstall it.
7. Apps are not launching on Big SurShut Down Mac With Keyboard
On the first day of the official Big Sur release, many users experienced problems with applications after they upgraded their Macs. Some reported apps not launching on Big Sur, while others complained about both programs and computers running slower than usual.
As it occurred, there was a problem with Apple's Online Certificate Status Protocol that failed to validate digital certificates for software on Macs. It disabled Apple's Gatekeeper, which in turn couldn't validate apps. If you experience a similar problem again, first check whether everything's okay with the Apple Servers.

10. Battery drain on macOS Big Sur
Several users complained that their Macs were showing battery service required warning after installing macOS Big Sur. It can be frustrating, especially if your Mac is brand new and has only a few battery cycles. If you’ve noticed that macOS Big Sur causes battery drain, resetting PRAM may help.
PRAM (parameter random access memory) contains control settings and configuration of your Mac. Resetting PRAM can fix what’s wrong with desktop, keyboard, volume, or battery settings.
After your Mac starts up, your settings should go back to default, and the battery issue should disappear. If this didn’t fix your battery issue, you might need to revert to Catalina.
Sometimes certain apps may eat too much of the CPU and battery resources. You can identify such programs by using the Activity Monitor. It's best to delete such applications and see if it resolves the battery issue. CleanMyMac X can help you with that — it deletes multiple apps and removes all traces of the application.
11. USB devices disconnecting randomly on Big Sur
This issue has been bothering 2020 MacBook Air and MacBook Pro users on macOS Catalina. The 10.15.6 update finally fixed the bug, but the macOS Big Sur seems to randomly disconnect USB connections too.
Disconnecting and reconnecting a USB hub may help. Some users resolved the issue by restarting their Macs. But this doesn’t fix the problem reliably. Hopefully, the developers will address this issue and present a solution with the next software update.
There are many ways in which Big Sur can run into problems. Thankfully, there are also lots of solutions. If you work through them step by step, you should be able to fix the problem. And using automated fixers, like CleanMyMac X, can help make the whole process much quicker and funnier.
