Change iCal Leather Interface to Aluminum in OS X Lion

Do you hate the way iCal looks in Mac OS X Lion? The leather interface of iCal looks like it’s right out of an iPad has definitely caused a split with users, people either love the way it looks or hate it with a passion. For the sake of this article, we’re going to assume you’re not a fan of the leather UI,

Replacing iCal’s Leather User Interface with Aluminum

To ditch the leather, you are going to replace the leather image files with aluminum versions:

  • Download the iCal aluminum replacement files by clicking here and unzip them, place this directory in an easy to access location like your desktop
  • Navigate to /Applications/ and find iCal
  • Important: Make a copy of iCal by selecting the app and hitting Command+D to create “iCal” – this is important because it allows you to revert the changes
  • Right-click on the original and select “Show Package Contents”
  • Open “Contents” and then open “Resources”
  • Drag all of the previously downloaded iCal aluminum UI replacement files into iCal’s “Resources” folder, replacing the contents (click ‘Apply to All’ and then select “Replace”)
  • Launch iCal and enjoy your aluminum interface

I have tested this and it works flawlessly. Just remember to backup the original iCal app (it’s only 42mb) in case you ever want to change back to good old cowhide. Keep in mind that future iCal updates will probably overwrite your changes too.

OS X Lion iCal replaced with Aluminum interface

A huge shout out to MacNix for creating the files to replace the UI. If you are not comfortable messing with apps resource contents, MacNix also offers an ‘automatic installer’ version that just writes over the files for you, but you’ll still want to duplicate as a backup.

If you want to get everything back to how it was before, all you need to do is swap in your backup copy of the app and rename the aluminum version again, and voila, back to leather:

    Thank you so much! I even stopped using the calendar because the interface got so icky. Thank you for the fix!!!

  2. Tracey says:

    Why can’t they just give you a few options? Not everybody is going to like one or the other….I can change a billion other things on this to make it work the way I want but I can’t choose a different calendar screen without basically going back in time to an older app.

  7. Polly says:

    Thanks so much for this download- much better!

    Does anybody know how to make the ‘all-day’ events section larger. I usually have around 10 all day events in my diary and can only see 6 at a time. I can scroll to see the rest, but as I look at my diary all the time, it’s a real pain.

    Thanks to anybody who can help me!

  21. victor says:

    You can also customize iCal’s look by replacing the “LeatherTile.png” and “LeatherTileFullscreen.png” files in resources, by another texture keeping the same files names and using the “Killall Dock” command in the terminal.

  22. TheAntibyte says:

    hey the files for this guide are missing can you repost them….

    I originally made this fix, I sometimes update the file but you can always find a live copy on

    excellent!! thank you.

  25. Tim says:

    The file is unavailable now. Any chance of getting it back? Cheers, Tim

  26. JeremyB says:

    Anyone have a solution for getting rid of the animated page flip while in the month view in the new iCal?

  27. Scott says:

    Anyone else have the files uploaded so that we can download again?

  28. Marcos says:

    “This file is no longer available” :(

  29. Ricardo Guerreiro says:

    Hate the new iCal (with passion). Fix the leather is good already but can we also have the All Day Events witha solid color bar? Now the events are less prominent in the cal. All the interface seems so dull! Nothing stands out and that was handy… Any solutions? Thanks

  30. Rudonja says:

    Thanks a lot for correcting this ugly mistake OS X Lion!

  31. yocheved says:

    thanks! I did not like the torn off paper pages things – that just annoyed me as I do lots of forward planning back and forth and do not want to see torn off paper pages. Small thing but I like it better this way – seems to me they should offer a few different skins you can switch between. Thanks so much – this was easy to fix with your help.

  32. Phineas says:

    Great tweak. How about a way to change the brown text in the UI to black after this fix?

  34. Sophie says:

    Thank you, what a relief not to have to live with someones misguided idea of design.

  35. AlastairM says:

    thanks for the fix – why do Apple think we want to replicate old paper systems on high power computers. Please change this soon, we want the future.

  36. gigipeeps says:

    Thanks so much that new look was just not me. It’s like someone got really bored on their cowboy retreat.

  38. parmetmusic says:

    Easily done. Bravo. Thanks.
    (The leather interface change produced the same response to seeing a guy wearing a toupé and wondering, “Ok, besides you, who really thinks that was a good idea?)

    Unless yanks have too much of the element SODUM in their diet and it’s obscured the ability to spell…

  51. Melanie says:

    Yay!!! Many thanks — I *hated* the beige pleather. Happy now. :)

  52. talltree says:

    Great hack, thank you!

    Now if someone can figure a way to show the Calendars, like in Snow Leopard (vs. Lion’s need to click each time in order to see your calendar list), I’ll be fully on with Lion’s iCal.

    • John says:

      I would love to see this, as well! I’m not a developer, so I’m making a request to the world that this gets created! Thanks.

  53. Pam says:

    I can not find how to turn the to-do list on the new iCal. Am I missing something?

  54. Dirk says:

    Hmm, seeing both side by side, i think Apple made the right decision ;-)

  55. It was only a matter of time. Thanks for this.

    However, I still prefer the old iCal sidebar. This new one makes it tougher to immediately hide and show certain categories. Also, the colours are fainter and the typography is different. Basically they made a bunch of changes that I, for one, don’t enjoy.

    The new address book is a complete mess. The old one was so much easier where you could easily see three columns: categories, names, and info. Now there’s pages to turn? Cmon.

  57. douglas says:

    Great tip

    BTW aluminium is the proper spelling

    • MacBill says:

      Either your spelling or the authors is correct. Just depends what part of the world you are in. =)

      • Alberto says:

        Call it Bauxite……

      • Nathan says:

        Lol indeed Aluminium is Dutch but Aluminum is English isn’t it?

        well, we spell that as “Bauxiet” so there still is a difference between those

        • George says:

          US English and British English varies massively in spelling and pronunciation of certain words.

          Both of you are correct.

          Aluminum is correct in the US
          Aluminium is correct in British English

          The method you use depends on who told you English should you be from a non-English speaking country.

    leather look was terrible… thanx… hope that it will be same with AdressBook…

  59. Parakeet says:

    Finally! I don’t like the bound desk calendar look, keep it consistent Apple
