  2. Open the Mac CD by double clicking on the "Mac" icon representing the Mac Hiarcs 7 CD-ROM: A window will open showing the contents (eg. folders and files) of the CD-ROM.
  3. Copy the folder "HIARCS FILES" from the "Mac" window to the "HIARCS 7" folder you created in step 1: You can do this by dragging the "HIARCS FILES" folder onto the "HIARCS 7" folder on your desktop.
  4. Open the engines folder in the "Mac" window. You will now see some chess engines with an H icon.
  5. Copy/Drag the "HIARCS 7.0 (PPC)" engine from the "Engines" folder just opened onto the "HIARCS 7" folder. If you wish you can also copy the HIARCS 6.0 engine. The 68K engines are provided for compatibility with old Macintosh computers.
