Hi @wangl2 ,

I had this same issue sometime last year. I'm not 100% sure what I did, but looking into my Sibelius 8.5 package now, I can see the fonts are all inside the /Library/Fonts folder.
I had created a Composer manifest to use with Sibelius in the past and the Fonts folder wasn't included in the manifest. Looking a bit further, I remembered that I probably installed an updated version of Sibelius on a computer that had it previously when I created the Composer manifest. So I had to use an older manifest to load the fonts from there. Thanks for reminding me of updating my manifest.

I've listed below all the fonts used by Sibelius and their location so you can add them to your manifest too.

I hope this helps you.

Thanks Luis.
I will copy those fonts out then from a working computer and just install them using ARD, instead of installing the whole Sibelius throughout the network.
Best Regards,

Just curious. Why do you prefer ARD to install Fonts or push out PKG's? It seems much easier with jamf.
