Gimp
GIMP is a free and open-source image editor used by photographers, graphic designers, digital artists, and hobbyists worldwide. It offers a comprehensive toolkit for photo retouching, digital painting, image composition, and animation, with support for layers, masks, channels, color management, and a vast library of filters and effects. GIMP runs on macOS, Windows, and Linux and has a large community of users and third-party plugin developers. The application is maintained by volunteers and distributed directly from gimp.org without Mac App Store distribution.

1 suggestionGIMP ships a native Apple Silicon build as part of its standard macOS distribution starting from version 2.10 and continuing through the latest stable release. If you are still running an Intel-only build, simply download the ARM64 version from gimp.org (or gimp.cc), extract it from the .dmg file, and drag it into your Applications folder. GIMP will automatically detect your Mac's architecture and serve the correct build. Note that GIMP is not notarized by Apple, so on first launch you will need to right-click the application icon in Finder and select Open to bypass the Gatekeeper warning — this is normal for open-source projects and does not indicate a security problem. After that first launch, GIMP will open normally. You can delete the old Intel build once you confirm the native version works for your needs.
