What to do if your Mac computer is running too slow, your Mac is running slow?

If your Mac is slow as a cow, that's your fault. You're a piece of software that you can't use a few times in your life, and your desktop is full of folders and icons, so it looks like you should sort it out. Uninstall the software you don't use, organize the folders (know that every little icon on the desktop takes up some system memory), turn off some system functions, such as system animations, stretch effects, smooth scrolling, etc.

Then, think about the hibernation state of your Mac, OS X systems are utilizing UNIX scripts to run automatically at 3:15am every day, 4:30am every Saturday, or 5:5 on the first day of the month

30am。If your computer is usually shut down or dormant during these times, then the temporary folder of the system will be full of junk files of the system, and your Mac will of course not run fast. If you use leopard, this script will run every time you start it.

1. Clean up your hard drive: If you encounter a slowdown in performance, the first thing you should do is empty the Trash.

2. Disabling functions: If you have freed up excess hard disk space, but the performance problem has not improved, then you can try to disable some functions again.

3. Monitor CPU and RAM: Use Activity Monitor to see which applications and processes are using the most CPU and RAM resources.

4. Generate System Diagnostics: Run System Diagnostics to generate a Mac diagnostic report, which contains files that allow Apple to investigate what problems exist with your Mac.

Your computer's startup disk might not have enough free disk space. To free up disk space, you can move files to another disk or external storage device, and then delete the files on your startup disk that you no longer need. macOS can also help you optimize your storage space 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 suggestion to use.

The app you're using might require more memory than your Mac can use directly. You can use Activity Monitor to see how much memory your Mac and apps are using. See View memory usage in Activity Monitor.

If it's not compatible with your Mac, quit any app. For example, an app may require a different processor or a graphics card. Refer to the documentation that came with your app for information about its system requirements.

To see what processing is on your computer, choose Apple menu > System Settings, click Hello in the sidebar, then click About This Mac on the right.

To see which graphics card your computer has, choose Apple menu > System Settings, then click General in the sidebar. Click About This Mac on the right, then click System Report. Click Graphics Displays to see the name of the graphics card installed on your computer.

If there's a problem with the disk, use Disk Utility to verify and try to fix any issues.
