Each modern MacBook comes with the original Mac OS as part of the computer’s package. If your MacBook is not performing as expected -- running slow or not loading applications properly -- you can restore your MacBook to the factory settings to fix it. In some cases, this will repair whatever is not working correctly with your computer. However, when restoring the computer to its factory settings you are removing all your files and personal data.
