Mojave Paint
A macOS image editor for Apple Silicon
Mac App Store macOS 15 Sequoia · Apple Silicon Changelog
About
A new macOS image editor with familiar key bindings and a somewhat retro aesthetic. Keeping the dream of the '90s alive!
This a tool for humans to make intentional and mathematically specific edits. That being said… we do have to acknowledge that some judicious use of AI features might make sense. Such features are not core to Mojave Paint, but more of a "why not?"
Built for Apple Silicon. Requires macOS 15 Sequoia.
