Mac users can pretty easily change their icons for hard drives and folders.

  1. Find an image that is at least 128px x 128px you’d like to use.
  2. Edit the image in Photoshop or any image editor able to set the background transparent. You can also add a drop shadow background if you want to get fancy.
  3. Save the file as a PSD or PNG image file.
  4. Install the Apple’s Developer Tools (available from Apple or your on your Mac OS X install disk.)
  5. Open Icon Composer (/Developer/Applications/Utilities) and drag the image file you made into each box. It will ask you for to confirm some things and be sure to select “Use Scaled Version” and “Extract Mask.” Save the file.
  6. Convert the ICNS file to RSRC using Icns2Rsrc.
  7. You’re now ready to switch the icon. Open the Get Info window for the icon, click on the miniature icon in the top left and press Command C. Then, use Get Info on the drive you want to change the icon on, click the mini icon and press Command V.
