Closing Resource Heavy Programs

    Open Finder (CMD + Spacebar) and type in Activity Monitor. Activity Monitor lets you see which programs on your Mac are taking up a lot of resources to run. Closing or uninstalling these programs can help speed up your mac.

    Click on Activity Monitor to open it. Activity Monitor can also be found within the Utilities folder inside the Applications folder
  3. Picture 24 of How to Speed Up a Mac
    Click on the CPU % tab. The higher the percentage, the more that resource is using up your CPU. Programs that use a lot of your CPU will slow down your computer.
  4. Picture 25 of How to Speed Up a Mac
    Close the programs with the highest CPU percentage. You can do this by clicking the program on the list and then the X in the top left-hand corner of the Activity Monitor.
    1. If you recognize the program and don't really need it, then consider removing the program from your mac. If it's making your mac run slow and you rarely use it then uninstalling it may be the best choice.
