If you find your Mac is running slowly, there are a number of potential causes that you can check.
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 optimise storage by storing files in the cloud and helping you identify files you no longer need. Choose Apple menu
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
To see which graphics card your computer has, choose Apple menu
Quit any apps you’re not using.
If you have problems with your disk, use Disk Utility to verify and try to fix any issues.
