GanttProject 2.6.1
GanttProject is a free, open-source desktop application for creating and managing Gantt charts, the standard visual format for project scheduling and timeline tracking. It lets users define tasks, set dependencies, assign resources, track progress, and generate reports — making it popular with project managers, small teams, educators and freelancers who need lightweight project planning without the cost of enterprise tools like Microsoft Project. The app supports import and export of standard formats including Microsoft Project files.
AI Recommendation
1 suggestionGanttProject is actively maintained open-source software. However, version 2.6.1 is quite old — the project has released newer versions in recent years, some of which may include native Apple Silicon support that was not present in your older build. Check the official GanttProject website or GitHub repository to see the current latest version and whether a native build is available. If a native version is not yet shipped by default, you should update to the newest available build to ensure compatibility as Apple removes Rosetta 2 in macOS 28 (September 2028). If the latest version still ships only as an Intel build, contact the maintainers to ask about Apple Silicon support, as the deadline for Rosetta removal is less than 28 months away.
