Hatari
Hatari is an open-source Atari ST, STE, TT, and Falcon emulator for macOS and other platforms, used to run classic Atari software.
What is Hatari?
Hatari is a desktop emulator for classic Atari ST family computers, including the ST, STE, TT, and Falcon. It helps users run older Atari operating systems, games, demos, and software on modern Macs and other supported systems. Hatari is aimed at retro computing enthusiasts, preservation users, and developers who want a more complete Atari environment rather than a simple game launcher. On macOS, it is commonly used to boot Atari disk images, test software behavior, and explore original system workflows with emulated hardware options. The app also supports use with EmuTOS, which can simplify setup for users who do not have original ROM images available. Hatari is published by the Hatari project and fits best as an emulator utility for retro software use.

Safety overview
Status: Safe
Hatari is legitimate emulator software used for retro computing. It may access local disk images, configuration files, and input devices as part of normal use. That behavior is expected for an emulator. Use software images and ROM material you trust, and keep backups of any disk image files you modify during testing or play.
Recommendation: Keep Hatari if you use Atari ST emulation, retro software, or classic game and demo files. If you no longer use it, you can remove the app without affecting macOS, though your Atari disk images and related files may still remain wherever you saved them.
