The MorphOS development team is proud to announce the public release of MorphOS 2.6 introducing support of PowerMac G4 systems. In addition to the extended hardware support, existing users will benefit from various bug fixes and a few new features. For an overview of the included changes, please read our release notes.
We strongly urge owners of PowerMac computers to carefully read our installation and troubleshoot guides before they attempt to install MorphOS for the first time. Existing users can upgrade via the familiar procedure but are encouraged to read the guides as well. MorphOS 2.6 is available for download in our files section.
