IPA-Download
A tool for installing historical versions of IPA
IPA-Download, also known as Pastel, is a macOS application designed for discovering, downloading, and managing historical versions of iOS applications. The software allows users to browse App Store content across different regions and automatically switch between available Apple accounts when changing storefronts. It supports retrieving version identifiers from multiple sources and provides tools for downloading specific application builds, including versions that may no longer be easily accessible through standard App Store interfaces. Account credentials and related information are stored securely using iCloud Keychain, and the application includes support for two-factor authentication workflows. Downloaded IPA files can be previewed, organized, and transferred directly to iPhones or iPads through AirDrop. Built with SwiftUI, the application is optimized for modern Apple Silicon Macs and offers multilingual support for users across multiple regions. -

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. -

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. -

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. -

SwiftLog
A Logging API for Swift
swift-log is the official, vendor-neutral logging API for Swift, providing a small, performant core that libraries and applications adopt to avoid logger lock-in. It defines common logging semantics and levels, plus a lightweight façade that backends can implement—so the same application code can run with different logging engines (e.g., OSLog on Apple platforms or custom sinks on servers). The package embraces Swift Package Manager, offers a clean Logger API, and is widely used across the Swift on server and Apple-platform ecosystems. The repo’s release notes and ecosystem links show active maintenance, CI coverage for recent Swift versions, and community-supplied backends. By decoupling the API from any one implementation, swift-log simplifies composition: frameworks can log consistently without dictating the logging stack to end users. It’s a foundational building block for production Swift services, tools, and apps looking for consistent, structured telemetry. -

KeychainAccess
Simple Swift wrapper for Keychain that works on iOS, watchOS, tvOS
KeychainAccess is a simple Swift wrapper for Keychain that works on iOS and OS X. Makes using Keychain APIs extremely easy and much more palatable to use in Swift. If you want to store the Touch ID protected Keychain item, specify accessibility and authenticationPolicy attributes. Do not run in the main thread if there is a possibility that the item you are trying to add already exists, and protected. Because updating protected items requires authentication. Additionally, you want to show custom authentication prompt message when updating, specify an authenticationPrompt attribute. If the item not protected, the authenticationPrompt parameter just be ignored. The same way as when you get a normal item. It will be displayed automatically Touch ID or passcode authentication If the item you try to get is protected. The same way as when you remove a normal item. There is no way to show Touch ID or passcode authentication when removing Keychain items. -

Connectivity
Makes Internet connectivity detection more robust by detecting Wi-FI
Connectivity is a wrapper for Apple's Reachability providing a reliable measure of whether Internet connectivity is available where Reachability alone can only indicate whether an interface is available that might allow a connection. Connectivity's objective is to solve the captive portal problem whereby an iOS device is connected to a WiFi network lacking Internet connectivity. Such situations are commonplace and may occur for example when connecting to a public WiFi network which requires the user to register before use. Connectivity can detect such situations enabling you to react accordingly. -

GPUImage 2
Framework for GPU-accelerated video and image processing
GPUImage 2 is the second generation of the GPUImage framework, an open source project for performing GPU-accelerated image and video processing on Mac, iOS, and now Linux. The original GPUImage framework was written in Objective-C and targeted Mac and iOS, but this latest version is written entirely in Swift and can also target Linux and future platforms that support Swift code. The objective of the framework is to make it as easy as possible to set up and perform realtime video processing or machine vision against image or video sources. By relying on the GPU to run these operations, performance improvements of 100X or more over CPU-bound code can be realized. This is particularly noticeable in mobile or embedded devices. On an iPhone 4S, this framework can easily process 1080p video at over 60 FPS. On a Raspberry Pi 3, it can perform Sobel edge detection on live 720p video at over 20 FPS. -
