3. Manage up your Mac startup
When you start up your Mac, some apps and processes are likely to be automatically running in the background, which is known to significantly slow down your system. We recommend quitting the number of background apps and disabling them from opening each time you start your device. This should help to improve the processing speed of your macOS.
To manage your Mac's startup, you follow these steps:
Open System Preferences.

Here’s how to help disable unnecessary widgets and extensions:
Click the Apple icon and select System Preferences.
Click on Extensions.
Select the Today tab on the left sidebar.
Uncheck the items that you don’t need on a day-to-day basis.
Close the window to save your changes.
