just saw that there's finally an update available for both windows and mac (comes with Keyscape 1.3.0f / Trillian 1.6.0f / StylusRMX 1.10.e, people seem to be reporting issues with those but I don't really need em).
So I'm using Ableton Live 10 on an OS X Mojave 10.14.5, and my broke ass grad student self has been wanting a working version of Omnisphere for some time.
