MacUSB
Creating bootable macOS and OS X USB drives has never been easier
macUSB is a macOS utility that streamlines the creation of bootable USB installers for macOS and legacy OS X versions, taking the complexity out of preparing installation media on modern Apple Silicon or Intel Macs. It automates disk formatting, installer detection, and content writing so that you can revive or install operating systems on older hardware—something that has become more difficult since Apple’s transition to its own silicon. With support for handling various disk image formats and applying necessary fixes for installers with older certificates, macUSB demystifies what was once a command-line-intensive process. Its goal is to make preparing bootable media accessible to users of all skill levels by intelligently managing installer images and systems, giving Mac users a straightforward path to restore or reinstall macOS across generations. -

MiddleDrag
Three-finger trackpad gestures for middle-click and middle-drag
MiddleDrag is a free, open-source macOS utility that enables middle-mouse button functionality using three-finger trackpad gestures, filling a longstanding gap for Mac users who rely on middle-click or drag interactions in many applications but don’t have a physical middle button. The app runs as a native menu bar application written in Swift, and it intercepts raw touch data using Apple’s private MultitouchSupport framework before the system gesture recognizer processes it, which allows three-finger taps and drags to be translated into middle-mouse events. It is designed to work seamlessly alongside built-in system gestures like Mission Control and Exposé so that default macOS behaviors remain intact while adding the missing mouse interactions. MiddleDrag’s GUI lets users configure sensitivity and behavior without using the terminal, and it can be set to launch at login for convenience. -

Pearcleaner
A free, source-available and fair-code licensed mac app cleaner
Pearcleaner is a small, native macOS utility that helps you fully remove applications by finding and deleting the leftover files they scatter across your system. After you drag an app into Pearcleaner (or select it from a list), it scans common Library locations for related caches, logs, preferences, containers, launch agents, and support files. Results are presented with clear paths and sizes so you can deselect anything you want to keep before sending items to the Trash. The tool favors safety: it avoids critical system areas, uses a conservative matching strategy, and relies on the Trash so you can restore items if you change your mind. Power users appreciate the transparency—no opaque “cleanup magic,” just an auditable list of what will be removed. For people who frequently test software or want to reclaim disk space after uninstalling large apps, Pearcleaner streamlines the tedious manual hunt through ~/Library and system folders. -

Hot
Hot is macOS menu bar application that displays the CPU speed limit
Hot is macOS menu bar application that displays the CPU speed limit due to thermal issues. CPU throttling is a power management technique in computer architecture whereby the frequency of a microprocessor can be automatically adjusted "on the fly" depending on the actual need, to conserve power and reduce the amount of heat generated by the chip. -

LinearMouse
The mouse and trackpad utility for Mac
The mouse and trackpad utility for Mac. If you are not comfortable with natural scrolling when using a mouse, LinearMouse can help you reverse the scroll direction. Since each device can be configured independently, there is no need to worry about the trackpad's travel address being affected. LinearMouse allows you to find comfortable cursor speed and acceleration and helps you move the pointer faster and more accurately. You can even disable cursor acceleration if you are a player or designer, to get the best pointer precision. -

2FAS Auth for iOS
Source code for 2FAS Auth iOS app
2FAS Auth for iOS is the official iPhone and iPad client for the 2FAS authentication platform, offering users a secure and privacy-focused mobile app to manage multi-factor authentication (MFA) tokens for their online accounts. The app generates time-based one-time passwords (TOTP) and counter-based one-time passwords (HOTP) that are widely required for logging into services with enhanced security, and it lets users scan QR codes or manually enter secret keys to register new accounts. Designed with native iOS conventions, it supports Face ID and Touch ID to quickly unlock the app while keeping authentication secrets encrypted locally on the device, so sensitive data never leaves the user’s control. The client is also structured to work offline, meaning you can generate codes without a network connection, and it integrates with companion browser extensions or other 2FAS sync tools so tokens can be backed up or restored across devices securely. -

Swift System
Low-level system calls and types for Swift
Swift System provides idiomatic Swift interfaces to low-level system calls and types, aiming to be the canonical home for these building blocks on all supported Swift platforms. It wraps platform details behind portable APIs while still allowing you to drop down to exact OS semantics when needed. The design follows Swift’s value semantics and protocol orientation to keep code predictable and testable. It’s distributed via SwiftPM with tagged releases, making it straightforward to pin versions in larger stacks. Over time, the library is intended to centralize foundational syscalls so other packages don’t reinvent thin wrappers. Escape hatches to exact platform behaviors when required. This consolidation improves consistency, documentation quality, and cross-platform behavior for systems programming in Swift. Portable, idiomatic wrappers for system calls and types. -

SwiftNIO
Network application framework for protocol servers and clients
SwiftNIO is a cross-platform asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Low-level protocol implementations are often a collection of ChannelHandlers that implement a protocol but still require the user to have a good understanding of SwiftNIO. Often, low-level protocol implementations will then be wrapped in high-level libraries with a nicer, more user-friendly API. High-level implementations are usually libraries that come with an API that doesn't expose SwiftNIO's ChannelPipeline and can therefore be used with very little (or no) SwiftNIO-specific knowledge. The implementations listed below do still do all of their I/O in SwiftNIO and integrate really well with the SwiftNIO ecosystem. SwiftNIO aims to support all of the platforms where Swift is supported. Currently, it is developed and tested on macOS and Linux. -
