So, as seemingly the Mac users currently miss all the nice Go-Oo features, I put up 3.0 RC4 Intel builds here. A word of warning, though: in comparison to Linux & Windows, the Mac version of Go-Oo has not yet received broad testing, so please consider this version unstable. Any feedback greatly appreciated – and if you want localized UI, there are language packs alongside the RC4 package (e.g. for the fr or de locale).
Just in case you want to try a build yourself: the wiki has a howto.
