"Supports macOS Tahoe on Apple silicon since Firefox 145. See [bug 1992212](https://bugzil.la/1992212).",
"Supports older macOS versions on Apple silicon since Firefox 147. See [bug 1993341](https://bugzil.la/1993341).",
"Does not support macOS on Intel CPUs. See [bug 2004105](https://bugzil.la/2004105).",

FF147 supports WebGPU on on all macOS versions on apple silicon in https://bugzilla.mozilla.org/show_bug.cgi?id=1993341.
Previously it was only supported on Tahoe - I can't find a bug for that, but this issue stated that it was added for Tahoe in 145. It isn't supported on Linux. It isn't supported on macOS on Intel.
I have updated the (partial) subfeatures in the 250+ places that support is recorded.
