  • 1) To format external hard drive for Mac, connect it to one of the ports on your Mac. Turn the drive on, and make sure it appears in the Finder. If it's the Mac's internal hard drive, of course there's no need to connect.
    • If the drive is internal, it should already show up in the Finder. If not (for example, if you installed a new drive that hasn't yet been formatted), look for it in Disk Utility in the next couple steps.
    • If you have already written data to the drive, back it up before proceeding to the next step.
  • 2) In your Mac's Finder, choose Go > Utilities. The /Applications/Utilities folder will open. Then launch Disk Utility.
  • 3) Click the Erase tab if it's not already selected. At the bottom of the window, you'll see some information about the drive you have selected. Look at the Partition Map Scheme entry. format mac hard drive
