The single most important thing to know is that Titanium Software builds a separate OnyX for each major macOS version, so you must download the build that matches your system rather than the newest one. The current release, 5.1.0, is built for macOS Golden Gate 27 and requires an Apple-silicon Mac; Intel Macs are supported only through older builds, the newest being 5.0.6 for macOS Tahoe 26. It is donationware — free to use and to distribute unmodified, with no registration.",
