No problems here. I used the Mac OSX installer. cosm.query shows up, but I have to type it in manually (i.e. it doesn’t appear under autocomplete). I’m a student of these guys at UCSB, so if one of the installations is actually missing externals, I could tell them directly for you.
I have no trouble creating an object like cosm.query in a Max patch but I’m not able to create a collective or standalone that incorporates these objects (although creating a collective and opening in a full version of Max does work), presumably because they’re not actually included as separate externals in the cosm package.
According to the post mentioned above, the issue has been reported already. However, thelizard, it would be great if you could mention this to Wes and Graham. Thanks!
