Psst…hey you…yea the one in front of the Mac. Go here: https://tapbots.com/ivory/mac/
Sorry about the short Mac alpha window yesterday. We ran into a TestFlight issue and are trying to get it resolved. We definitely want to allow more of you access to the Ivory for Mac alpha. Will hopefully have more info in a couple days. Thanks for your patience! 🙏
