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. -

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. -

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. -

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. -

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. -

Attabench
Microbenchmarking app for Swift with nice log-log plots
Attabench is a microbenchmarking app for macOS, designed to measure and visualize the performance of Swift code. This app is for microbenchmarking low-level algorithms with one degree of freedom (usually size). It works by repeatedly performing the same operation on random data of various sizes, while continuously charting the results in nice plots. Attabench's default log-log plots are ideal for seeing your algorithm's performance at a glance. Attabench was originally created to supply nice log-log charts for my dotSwift 2017 talk and Optimizing Collections book. At the time, it seemed easier to build a custom chart renderer from scratch using Core Graphics than to mess with a bunch of CSV files and pivot tables in Excel. (It has to be noted though that this opinion has been somewhat weakened during the implementation process.) -
25
Bagel
A little native network debugging tool for iOS
Bagel is a little native iOS network debugger. It's not a proxy debugger so you don't have to mess around with certificates, proxy settings etc. As long as your iOS devices and your Mac are in the same network, you can view the network traffic of your apps separated by the devices or simulators. Most basic usage is to start Bagel iOS before any network operation. Since Bagel exposes every request info to the public it would be better if you disable it for the store versions. By default, Bagel gets your project name and device information. The desktop client uses this information to separate projects and devices. You can configure these if you wish. Bagel framework communicates with the desktop client by using Bonjour protocol. You can also configure these Netservice parameters.
