How to change the default iCal Leather skin in OS X Lion

Not a fan of the new look that iCal and Address Book are sporting? The following guide will show you how to revert to the ‘aluminum’ look for iCal, which is more consistant with the rest of OS X.



  1. Make sure to quit iCal if it’s open.
  2. Note: this step is important. Start out by making a back-up of your current iCal. Locate iCal in your Applications folder, ‘right-click’ (ctrl + click) it, and select Compress “”

  4. Now you’ll see an iCal .zip file in your Applications list. Select it, hold down the command (Apple) key, and drag it to your Documents folder (or any other folder you want to store the back-up of iCal).

  6. Download this .zip file and open it (doesn’t matter where).
  7. Back in your Applications folder, ‘right-click’ (ctrl + click) iCal again, and this time select Show Package Contents.
  8. Select the Contents folder and then the Resources folder.

  13. When the Copy window appears, place a check in the box labeled Apply to All, and click the Replace button.

  19. When iCal updates, it’s very likely that it will revert back to the previous ‘leather’ style. You’ll need to repeat the steps in this tutorial to get the aluminum style back.
  20. If you ever have issues, remember that you have the backup copy of iCal as a .zip file. Use it if needed!
  21. Thanks to macnix for creating all the necessary files!

  1. same here, file no longer available? would be great to have it because this ‘leather look’ doesn’t make my eyes happy…thanks!

  2. tried to follow instructions but zip file no longer available.
    Thank you for the instructions.

  3. awesome! the new default chrome on ical (& address book) show a remarkable lack of taste on the part of certain apple product managers. i’m surprised jobs allows them to create this ugliness. thanks for the fix.

  4. Hi! Thanks I just installed your skin! What was apple thinking. I don’t understand the new iCloud logo either.

    There’s one more ‘problem’ though. In iCal, the font of ‘Day Week Month Year’ ‘Timezone’ and ‘iCal’ are still kinda brown/ yellowish.

    Do you know a way to change this?
