I arrived a few days ago, via Processing, thanks to a posted comment. It is nice and quiet here, and it is now time perhaps, for me to introduce myself to the NodeBox 1 forum as I run Version 1.9.5 on OSX v10.6.8
I may be able to upgrade a HD partition to run Mavericks, but as yet, I do not have an Apple ID., so upgrading is not an immediate option. In any event, it is as well to cut my teeth on NodeBox 1 Version 1.9.5 before upgrading to Version 1.9.7rc2.
