How to Partition a Mac With HFS

Computers running the Mac OS X operating system use the Hierarchical File System Plus to maintain files on the computer's hard drive. HFS+ supports the features necessary for the UNIX-based Mac OS X, including file and folder permissions, and resource forks. Every Mac must be formatted with HFS+ for Mac OS X to install to the hard drive. You can partition and format a Mac with HFS+ by booting from the installation disc and running the Apple Disk Utility.

Instructions

1. Insert the Mac OS X installation disc into the disc drive, then restart the computer.

2. Press and hold the "C" key on the keyboard until the Mac begins to boot from the disc.

3. Click the blue "Next" arrow.

4. Click the "Utilities" menu at the top of the screen.

5. Click "Disk Utility."

6. Click the Mac's internal hard drive in the left column of the window.

7. Click the "Partition" tab.

8. Click "1 Partition" under "Volume Scheme."

9. Click "Apply," then click "Partition." The Mac is now formatted with HFS and the Mac OS X operating system can be installed.

Tips & Warnings
