It’s still not perfect for Intiface desktop, as there are moments now and then when it doesn’t keep up, but based on the animations I have tested, I feel like it’s good enough now.
As for the Mac version. I haven’t been able to confirm that everything works in intiface-bridge as I’m unable to start the intiface server on my mac. So if you have a mac and is able to use intiface desktop, please let me know if it’s working for you.
