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! 🙏
Rob Mathers@ivory would it be possible to just do distribution outside TestFlight for the Mac?
@robmathers Not without a ton of work. We'd have to build an update system and everything. We are already going to be close to releasing on the app store so just want to let 10k users use it until we ship.
