The Macintosh applications, source code and articles on these pages were written by Bill Cheeseman. They are meant to be useful in their own right, as well as informative to developers.

Each link takes you to a page with more information, where you can also download a disk image, zip archive or PDF file containing software, its source code and its documentation, or other information. Licensing terms, where applicable, are explained on the individual download pages.


TagMinder (2011) is a set of AppleScript scripts enabling you to tag Finder items with words or phrases. Tags allow you to find files by tag without regard to their location, adding an organizing principle to your files that is separate from and more flexible than the filing system's folder structure. You can find all files having specified tags either by using Spotlight or by running the Reveal Tagged Items in Finder script.

PackageMaker 3: Building a Leopard or Snow Leopard Installer Package Step by Step, version 1.1

The PackageMaker 3 PDF file (2010) provides detailed step-by-step instructions for creating a flat installer package for Mac OS X 10.5 Leopard and newer. It describes a typical installation scenario in which an application and a shared framework are installed with all the bells and whistles, including options to relocate the application and to install the framework without the application. This article is based on the original installer for the free Event Taps Testbench application.


Lucubrator (2009) demonstrates how to use the Core Location frameworks introduced in Mac OS X 10.6 Snow Leopard to detect your current location. At the time of this writing, Macintosh hardware is limited to the same technique used by the iPod to determine location. If you have not disabled Location Services, if you have AirPort turned on, if you are connected to the Internet, and if you are in range of a WiFi hotspot that is in the Skyhook database, Lucubrator will find you. When it does, click the Show on Map button to show your location in Google Maps. If you’re in a major city, you’re probably in luck. Otherwise, you might have to add your local hotspots to the Skyhook database yourself. We’ve had reports of success from Boston, Hamburg, Paris, and Sydney.

Wareroom Demo

Wareroom Demo (2005) is a demonstration application that implements the complete AppleScript Standard Suite (plus a few custom commands) in a Core Data application. It requires Mac OS X 10.4 Tiger and newer. It is intended to demonstrate a variety of techniques for making any Cocoa application scriptable using Cocoa Scripting, but with particular focus on some special techniques that are needed to make a Core Data application scriptable. (Note that more recent versions of Apple’s Cocoa frameworks provide easier techniques for accomplishing some of these tasks. Wareroom Demo has not been updated for the latest versions of Core Data.)


QSW_UUID (2004) is an Objective-C Cocoa framework for using Apple's Core Foundation UUID API in your Cocoa applications. It is written for Mac OS X 10.2 Jaguar and newer.

A universally unique identifier (UUID) is an identifier that is unique across the space of all UUIDs and unique across time. It can be used to reliably identify and distinguish persistent objects in many contexts, such as identifying remote procedure calls on the internet, identifying header files in software, and identifying individual records in multiple databases. A UUID generator can continue generating unique UUIDs until approximately 3400 A.D.

Vermont Recipes 1

Cocoa Recipes for Mac OS X: The Vermont Recipes (First Edition) was published by Peachpit Press in 2003. You can read the Errata and download the source code and project files here. Note that the project can only be opened in older versions of Xcode.
