Customizing The Mac OS X User Interface

by Scott Chitwood, http://www.resexcellence.com

Part III, Appearance Themes

One of the big gripes regarding the user interface in Mac OS X is that with each OS release, Aqua has become inconsistent and too varied in its appearance. Panther gave us the much debated and despised brushed metal Finder; Tiger has adopted yet another variation of Aqua with a plasticized, unified toolbar in the System Preferences and Mail 2.0.

So what can users do to overcome these UI distractions? We can give Aqua a makeover using third-party appearance themes. The Macintosh theme community is blessed with a number of dedicated and outstanding artist/developers whose works allow us to change our user interface with the click of button!

Apple first introduced appearance themes in Mac OS 8.5, but never supported their use. The final candidate shipped with Apple Platinum; the Apple developed themes Hi-Tech, Gizmo, and Drawing Board were withheld from the general public. Lucky for us, creative third-party developers stepped up to the plate and gave us a variety of themes to toy with.

As we stepped into Mac OS X, third-party developers were putting their modification skills to work as early as the public beta release, and they’ve been going strong ever since.

Switching out theme files early on required one to manually backup and copy the Extras.rsrc and Finder.rsrc, a simple task (if one knows where to look) and still my personal favorite method of test driving themes, even though it’s been a long time since there’s been an opportunity to do so. The easiest way to find the path for the Extras.rsrc and Finder.rsrc is to launch the Terminal and paste in the following command.

locate Extras.rsrc

You should see the following result, or one quite similar:

/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/ HIToolbox.framework/Versions/A/Resources/Extras.rsrc

Copy and paste the results (without “Extras.rsrc” on the end) into the dialog box of the “Go to Folder…” command in the Go menu. The directory is owned by the system so you can’t make any modifications to it without changing permissions. Our recommendation is to just take a look around the folder, and don’t mess around with the files unless you’ve backed them up and know what to do if something goes wrong.

Later on we were able to use third party applications that did the work of switching out system resources for us. Those programs did a nice job of making the switch, but they were also somewhat dangerous to use. Switching out system resources is an inherently risky task; the average user may not be aware of the pitfalls, such as using a theme file for an older OS release on a newer version—a recipe for disaster if there ever was one.

2003 ushered in the modern era of appearance themes when Unsanity released ShapeShifter, a preference pane that applies themes by directing Mac OS X to load and overlay the graphics in theme files (guiKits) on top of the system resources. This revolutionary idea brought appearance themes to the masses and is by far the safest method to date for changing the Mac OS X user interface.

ShapeShifter lets you apply appearance themes, desktop pictures, and system icons as separate entities, so you can pick and choose what to use from any installed guiKit. And, if you’ve downloaded and purchased Mighty Mouse, you can also change the system cursors from within ShapeShifter!

Where can you find appearance themes for Mac OS X and earlier? Stop by the ResExcellence theme archive to get started—there are plenty of links to third-party theme developers that we encourage you to explore and enjoy! If you’d like to try your hand at creating themes, download a copy of ThemePark by Jason Harris at Geekspiff.
