Software
I develop and maintain free, open source software in my spare time. Most of the software packages available here are for Apple's macOS. They are distributed as free software under various permissive open source licenses. All of them are on GitHub if you want to lend a hand or submit feedback.
If you find my software useful, please make a donation.
Platypus
Platypus is a developer tool that creates native Mac applications from command line scripts. Such scripts can then run natively as applications via the macOS window environment instead of running through a terminal client.
Sloth
Sloth is a Mac application that shows all open files and sockets in use by all running processes on your system. This makes it easy to inspect which apps are using which files and sockets. It's basically a friendly, exploratory GUI for lsof.
FastDMG
FastDMG is a macOS utility to mount .dmg and other disk images quickly, efficiently and without any unneeded nonsense. It's a very fast and reliable replacement for Apple's DiskImageMounter.
KatSearch
Fast native Mac power-user app to quickly find files on entire HFS+/APFS volumes by scanning the file system catalog. Do you miss the good ol’ days before Spotlight, when search on the Mac simply scanned the filesystem? Yeah, me too.
ManDrake
Native man page editor for macOS with syntax highlighting and live mandoc syntax validation. It also displays a live-updating rendered preview of the man page during editing.
searchfs
Command line tool to quickly search by filename on HFS+ and APFS volumes. Searching takes place at the driver level using the file system catalog. This means the volume's entire directory tree can be scanned much faster than with a standard recursive hierarchical search.
osxiconutils
A set of command line utilities for creating, converting and working with Apple .icns files and Finder file icons.
Phew
Phew is a FLIF image viewer for macOS that can open FLIF images, and export them to PNG, TIFF, and other formats. With the accompanying QuickLook plugin, FLIF images show thumbnails and previews in the Finder and Spotlight just like regular images.
