Install for Updated Messages Updates
While there are new emoji coming with macOS Catalina, they won't make it until a future release. What you can count on is better iMessage support.
Even with iMessage in the cloud, the experience on the Mac isn't as good as on the iPhone or iPad. You miss out on Stickers and Effects.
With the macOS 10.5 beta, you can try out these new features on your Mac so that you finally get the full iMessage experience.
This feels like it is a long time coming, and we're excited to finally send messages with lasers from the Mac.
