Not smooth scrolling MacBook Air M1

Hello maksim_p,

Let's use the steps below to boot your Mac into safe mode:

1. Shut down your Mac.

2. Turn on your Mac and continue to press and hold the power button until you see the startup options window.

3. Select your startup disk, then press and hold the Shift key while clicking “Continue in Safe Mode.”

4. Log in to your Mac. You might be asked to log in again.

You can also find those steps in this resource: How to use safe mode on your Mac

It can take a few extra minutes to boot into safe mode. Your screen may flash or flicker while in safe mode. Those behaviors are expected. Testing in safe mode runs a check on your disk, removes some cached files, and can help isolate conflicts with startup items. Once you've tested that behavior in safe mode, you can restart to leave safe mode.

Should that still persist, do you experience the same behavior with built-in apps such as Safari?

Also, approximately how long have you been experiencing this behavior?

Let us know, and we'll keep moving forward based on those details.

Hello maksim_p,

Welcome to Apple Support Communities.

We recommend trying the steps here: If your Mac runs slowly - Apple Support

"Your computer’s startup disk may not have enough free disk space. To make disk space available, you can move files to another disk or an external storage device, then delete files you no longer need on the startup disk. macOS can also help you optimize storage by storing files in the cloud and helping you identify files you no longer need. Choose Apple menu  > System Settings, then click General in the sidebar (you may need to scroll down). Click Storage on the right, then click the storage recommendations you want to use. 

An app you’re using may require more memory than your Mac has easily available. You can use Activity Monitor to see how much memory your Mac and apps are using. See View memory usage in Activity Monitor. Also see the documentation that came with the app to find out its system requirements.

Quit any app that isn’t compatible with your Mac. For example, an app may require a different processor or graphics card. See the documentation that came with the app for information about its system requirements.

• To see what processor your computer has, choose Apple menu  > System Settings, click General  in the sidebar, then click About on the right.
• To see which graphics card your computer has, choose Apple menu  > System Settings, then click General  in the sidebar. Click About on the right, then click System Report. Click Graphics/Displays to see the name of the graphics card installed your computer.
• Quit any apps you’re not using.
• If you have problems with your disk, use Disk Utility to verify and try and fix any issues."

Completing these steps may resolve this.

Let us know if you have further questions.

Take care.
