All-mighty Mac system monitor
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.

Try the best tools that help you find and kill processes hampering your Mac's performance.
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:

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 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.

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.
