If your Mac runs slowly

If you find your Mac is running slowly, check any open applications to make sure they’re compatible with your computer. Or you may need to increase your hard disk space or repair your hard disk.

  • An application you’re using may require more memory than your computer has. To see how much memory your computer has, choose Apple menu > About This Mac. See the documentation that came with the application to find out what it requires. To find out how to increase your computer’s memory, see the documentation that came with it.
  • Quit any application that isn’t compatible with your computer. For example, an application may require a different processor or graphics card. See the documentation that came with the application to find out what it requires.
    • To see what processor your computer has, choose Apple menu > About This Mac.

    • To see what graphics card your computer has, choose Apple menu > About This Mac, click More Info, and then click Displays.

  • There might not be enough free disk space on your computer’s startup disk. To make disk space available, you can move files to another disk and then delete files you no longer need on the startup disk.

    Increase disk space

  • Quit any applications you’re not using.
  • If none of these suggestions work, you may need to repair your computer’s disk in Disk Utility.
