Commander
AppleCommander is a utility for working with Apple II disk images, used primarily by retro computing enthusiasts, educators, and developers who emulate or preserve vintage Apple II systems. It provides both a graphical interface and command-line tools for creating, inspecting, and extracting files from Apple II disk image formats (such as .dsk, .do, .po, and others). The application is useful for managing software collections, transferring files to and from emulators, and educational projects involving classic computing history. AppleCommander is an open-source Java application.
AI Recommendation
1 suggestionAppleCommander provides separate native builds for Apple Silicon and Intel Macs. If you are still running an older Intel build under Rosetta, download the current version from the AppleCommander release page and explicitly select the aarch64 (Apple Silicon) variant labeled AppleCommander-macosx-aarch64-VERSION.jar. The key point: do not simply re-download from the main page without checking the filename — you must ensure you get the aarch64 build, not the x86_64 build. You will also need Java 21 or later installed on your system; if you do not have it, install OpenJDK via Homebrew (brew install openjdk@21) or download from AdoptOpenJDK. Once you have the correct JAR file and Java version, simply double-click to launch. For command-line use, AppleCommander is also available via Homebrew (brew install applecommander) and will automatically get the native variant that matches your system.
