Free uml diagram software for mac

jUML is a UML diagram application that is capable of reverse engineering Java source code to create relationship diagrams, source code generation based on a user created UML diagram, and saving/restoring of jUML projects.

System requirements:
-

Enhancements
- This is a working release. You can either import files to show relationships or create a new diagram and generate/test code and save the project.

UML implements UML statecharts in C++ and Java. Next to the standard elements of FSMs, hierarchical and concurrent states are as well supported as pseudostates, segmented transitions, timed events and an eventqueue using a thread pool.

Main features:
- Very easy to use API (See documentation for details)
- Implemented in C++ and Java
- Does require only a very small amount of memory
- Complete object-oriented design (all elements are real objects)
- Parallel usage of the statechart infrastructure. Runtime specific data is encapsulated in a small object.
- Support for many elements of statecharts
- Simple, hierarchical and concurrent states
- Start and final states
- History and deep-history pseudostates in hierarchical states
- Fork- and join pseudostates for concurrent states
- Segmented transitions using junction points
- Transitions can cross borders of composite states (implicit entry/exit)
- Entry, do and exit actions in states
- Events, guards and actions for transitions

System requirements:
- Java

Enhancements
- Fixed a ConcurrentModificationException bug when handling timeout events.
- Fixed shutdown procedure when the created threads are non-deamon threads.

BOUML is cross-platform UML 2 tool box that runs under Mac OS X(Intel), Unix/Linux/Solaris, and Windows.
BOUML is very fast and doesnt require much memory to manage several thousands of classes, see benchmark.
BOUML is extensible, and the external tools named plug-outs can be written in C or Java, using BOUML for their definition as any other program. The code generators and reverses are ones of the pre-defined plug-outs included in the BOUML distribution.

Main features:
- it is free
- it runs under Mac OS X, Linux/Unix/Solaris, and Windows thanks to Qt
- it allows to program simultaneously in C , Java, Php, Python and IDL
- thanks to a full access to the generated forms, you are the master and you decide what must be generated
- it is extensible, and the external tools may be developed in C or Java, using BOUML for their definition as any other program.
- it is very fast and doesnt require much memory to manage several thousands of classes

Enhancements
- Browser search allows now to search for elements depending on their stereotype.
- The menu miscellaneous has the new toggle completion in dialog, it is set by default to be compatible to the behavior of the previous releases. When it is set and you enter a string in a list of choices (combo box) in a dialog, an auto completion/search is done, note this one is non case sensitive (Qt limitation). If you dont like this auto completion/search, unset the toggle.
- Internal extension of the Plug-out API for Java Roundtrip.
- C++ Generator 2.13
- A dependency stereotyped friend produced a wrong code in case the target class was a template, fixed.
- Follow the new API.
- Plug-out upgrade 1.13
- A crash occured when you upgraded an old plug-out without Python management, fixed.
- Follow the new API.
- Java Roundtrip 1.0
- New plug-out, please refer to the documentation
- C++ Reverse 2.10
- Java Generator 2.17
- Java Reverse 2.13
- Java Catalog 2.12
- Idl Generator 2.10
- Php Generator 1.5
- Php Reverse 1.3
- Python Generator 1.1
- Roundtrip body 1.8
- Follow the new API.
- XMI Generator 1.4.6
- When a parameter of an operation doesnt have type the token UML:Parameter wasnt closed, fixed.
- XMI2 Generator 1.10.2
- The base type of a class stereotyped typedef is now produced in an extension form supposing you ask for them

CanvasUML 0.1.1 can be a really useful free Cocoa-based application for Mac OS X Tiger which lends you a helping hand in creating simple UML Class Diagrams. CanvasUML is alpha-quality software and should not be used for mission critical work (as if there were such a thing as mission critical UML diagramming?). CanvasUML is built using Apple's WebKit framework, tag, WebKit's support for ContentEditable.

CanvasUML should be thought of as an exploration of what is possible using the above technologies rather than a solid app. It is basically an experiment to see how far the element can be pushed.

Major Features:

1. CanvasUML is implemented with an unholy mix of HTML, JavaScript, Cocoa, CSS, the tag, contentEditable, and Safari JavaScript Drag n Drop.
2. The main window in a CanvasUML document consists of a WebView (basically like a Safari window) filled by a large, resizable tag. The class/instance boxes are DHTML
   s with nested contentEditable

   s for the title, attribute, and operations sections. The association lines and the shadows behind the class boxes are, of course, drawn by the tag. CanvasUML saves its doucuments as HTML files which link against a shared CSS stylesheet and JavaScript library stored in the CanvasUML app bundle (take a look if you're curious).

Requirements:

• Mac OS X 10.4 Tiger or later.
