Checksum Validator 1 is launched as a simple yet effective tool with which you can easily calculate and validate checksums (SHA-1 or MD5 digests) for files that you download (or will upload). By comparing a site's published checksum with your calculated checksum, you can verify that your download matches the site's official copy; free from corruption or tampering (unless the site's checksum was also tampered with).
Everything needed to calculate checksums is in Mac OS X, this is just much easier and quicker, and let's face it, the easier and faster, the more likely you will actually verify these downloads.

XML-RPC Client 1.6
XML-RPC Client - Debugger for developers setting up/accessing XML-RPC services more>> XML-RPC Client - Debugger for developers setting up/accessing XML-RPC services
XML-RPC Client is a free Cocoa-based developer tool for Mac OS X Tiger that allows you to access and debug XML-RPC web services from the comfort of your desktop.
Its not much? and its not very full-featured. Basically, the suitably-named "XML-RPC Client" allows you to point at an arbitrary XML-RPC service URL available on the network, specify a method and (limited) parameters, and view the response in a readable display. Its pretty much meant to be used as a handy, graphical debugger for developers setting up or accessing XML-RPC services. I kinda needed something like this at work, and was tired of using the command line for something for which there should be a nice little graphical tool. Theres still work to be done. At this point, you can only send arguments of some of XML-RPCs "primitve" types: string, int, double, and boolean are supported. structs, arrays, base64 and dateTime.iso8601 are not yet supported. That means that you may not access any service methods requiring parameters of those types using XML-RPC Client. Release early and release often, right?
Enhancements
- Now a Universal Binary.

Free WYSIWYG XML editor, cross-platform, supports DITA, Docbook, and other popular XML formats. more>>
An easy-to-use WYSIWYG XML editor intended for students, open-source projects, and other non-commercial uses. Authors with virtually no XML experience can start working with structured content in a familiar environment that looks much like a conventional word processor.

Serna offers exceptional DITA 1.1 support and comes with integrated DITA Open Toolkit. Flexible visualization of DITA maps and topics with the ability to resolve referred content and in-place editing of local conrefs greatly simplify DITA authoring.
