Save a Document

After you create a document and make changes to it, you can save the document to preserve your work. When you work on a document, OS X stores the changes in your computer’s memory. However, OS X erases the contents of the Mac’s memory each time you shut down or restart the computer. This means that the changes you have made to your document are lost when you turn off or restart your Mac. However, saving the document preserves your changes on your Mac’s hard disk.
