How to Save to an External Hard Drive on a Mac

By K.C. Winslow

The hard drive of a computer has a fixed amount of space. Using an external hard drive with a Mac gives you access to additional storage space. External hard drives provide a means of backing up information and of moving information to a different computer. You can save files to an external hard drive from the "Save" menu of any application on your Mac. When you save to an external drive, the only copy of the file is on the external drive.

Open the file you want to save to the hard drive. Click the "File" menu of the application and select "Save As."

Step 3

Step 4

Click the "Save" button to save the file to the external hard drive.
