Mac users may be interested to know that we have today released a very minor update for the English-language version of Sibelius 3.1.3 that allows it to use the Sibelius 4 fonts. This new build has no functional changes over Sibelius 3.1.3, except that it will now work correctly with the Sibelius 4 fonts (installed by both the current version of Scorch and Sibelius 4 itself). You only need to install this update if you still wish to continue working with Sibelius 3 on your Mac.
