Skim is a PDF reader and note-taker for OS X. It is designed to help you read and annotate scientific papers in PDF, but is also great for viewing any PDF file. Skim requires OS X 10.10 or higher.

Video Projector/Monitor Calibration Software orginally developed as ColorHCFR. This code base is based off version 2.1 and will aim for a more open development process. The opensource version integrates an ArgyllCMS interface for continued meter support and development. If you feel the program has been of value to you since I started working on it about 3 years ago please consider a contribution via the link below. Thanks! -zoyd https://www.paypal.me/zoyd

Lynkeos is a Cocoa® application dedicated to the processing of astronomical digital images taken through a telescope. It is optimized for SSE vectorized instructions sets, multi-processor and multi-core machines.

A multiplatform C++ library for dynamic generation of Excel .xls files containing multiple worksheets. Unlike .csv files, these can be directly opened by Excel and thus provide an excellent way to output large data sets that require further analysis. To see the latest changes, select "Files" and view the README text displayed at the bottom of that pane. IMPORTANT: Major changes are contained in the current SVN source. If you have time please try to use it or the xlslib-package-2.4.0b1.zip archive, and enter bug reports on any problems! Changes: - library specific strings now in their own namespace - iOS Objective-C library - most project files updated (MSVS etc) - C bridge now supports formulas Note: there is a related SF project, libxls, to read Excel files.

DarwiinRemote is a tiny program & library which reads data from and sends data to Nintendo Wii Remote (Wiimote), nunchuk, & classic controller.

A native Macintosh front-end and distribution for the GAP computer algebra system. It provides a Mac-like command editing environment and save/load, while making available graphical libraries compatible with xgap.

N.B. SuperCollider is now hosted at GitHub, and the most recent versions can be downloaded from there. http://supercollider.github.io A real time audio synthesis engine, and an object-oriented programming language specialised for music. SuperCollider was created in 1996 by James McCartney, now (since version 3) released as free software.

Darling is a free and open source runtime compatibility layer—akin to Wine—for Linux that allows native macOS (Darwin) applications to run directly without hardware emulation. It implements macOS libraries and frameworks, enabling macOS binaries to execute on Linux. Darling has support for DPREFIXes, which are very similar to WINEPREFIXes. They are virtual “chroot” environments with an macOS-like filesystem structure, where you can install software safely. The default DPREFIX location is ~/.darling, but this can be changed by exporting an identically named environment variable. A prefix is automatically created and initialized on first use. Please note that we use overlayfs for creating prefixes, and so we cannot support putting prefix on a filesystem like NFS or eCryptfs. In particular, the default prefix location won't work if you have an encrypted home directory.

EasyChem is designed to draw chemical molecules in an intuitive way, with a very high quality (designed for book-publishing). Exporting is done to various formats (PostScript, Fig, LaTeX, etc.) to help you integrate your drawing in any software you use.

RSM (Radiation Spectrum Method) is a 2D rigorous tool to solve the Maxwell equations for the propagation of light in integrated optics or photonics devices. It makes use of an eigenmode expansion method to solve the electromagnetic problem. This software running on Windows and MacOS comes with a GUI that permits to define with the aid of files or scripts the arbitrary and complex geometry of the waveguide. Of that way any waveguide geometry can be handled. Several plots are available : refractive index plot, field propagation plot and modes spectrum plot. This permits, with the interpretation of the guided and radiation modes spectrum, a physical understanding of the propagation mechanisms in the integrated optical device under evaluation. The complex geometry of the component is discretized in a stack of multilayer dielectric waveguides. See : https://ipp.icube.unistra.fr/index.php/Photonics_Modeling_and_Simulation:RSM

Various computational physics projects for the Mac / GNUStep platforms.

iRad is a DICOM workstation written in Cocoa for MacOSX. Using QuickTime, OpenGL, and open source databases iRad aims to provide an easy and efficient way to review medical images from CT, MRI, ultrasound, and other DICOM sources such as angiography a

The purpose of the CoCalc project is to develop a simple RPN calculator application for use on laptops running OS X. It has been developed in Cocoa and Objective C, although it may change to a PyObjC application in the future.

An OS X screen saver that renders a 3d "perpetual motion" desk toy with up to 10 weighted rings.

Wii joystick interface. Wiiji is the perfect joystick solution for Wii remotes on Mac. Wii remotes will appear as joysticks to the OS. It does this through a kernel extention. It can emulate keyboard input. It runs in the menu bar.

MatrixGen is a Bioinformatics application used to generate scoring matrices from analysis of aligned Amino Acid and DNA data sets. These matrices can then be used by Clustal to generate more accurate alignments. Based upon the Henikoff BLOSUM method.

6Vertex is an Objective C/Cocoa application (and standard C functions) for computing and visualizing matrix models generated with the 6-vertex model for computing boundary shapes and phase transition shapes for differently weighted vertices.

ACNexus is a bluetooth sensor device, communicating with various clients such as mobile phones. The software suite consists of: ACNexusBT (Arduino firmware), ACNexusMobile (J2ME Phone App), ACNexusQC (Quartz Composer Plugin), ACNexusX (OS X app)

A framework of drivers on which generic astronomical applications can be built.

Computational modelling is a interdisciplinary field spanning many techniques and programming languages. AgenTools is a project dedicated to establishing increased modularity in scientific computing packages and a portal linking to other existing project

Aircraft navigation receiver using software-defined radio (SDR)

ArchiScale is an easy-to-use Mac OS X software that converts distances using a user-defined scale. It is also able to determine which scale is the best to draw something on a given paper format. This software is useful for students in first years of architecture schools, when you work without CAD-softwares, and for people using non-numerised documents with uncommon scales.

Astral Projection is a testing tool for iOS applications that use the CoreLocation framework. AP allows for testing location-aware apps on both the device and the simulator, using configurable location data sources like a GPX file or a remote agent.

A replacement manager for the BOINC software on Mac, written to use native UIs and yield better control.
