Messages
When iOS 10 was released over two years ago, Apple’s Messages app got a huge update, adding features like stickers, effects, and “iMessage Apps” with their own dedicated section on the App Store. However, its macOS counterpart was left out of the fun, still providing only very basic messaging functionality, with limited abilities to even display the richer content available from the iOS version. In fact, about the only significant new feature that Messages on Mac has gained in the past few years is iOS 11.3’s Messages in the Cloud, allowing for secure iCloud-based storage and sync of a users’ entire messaging history.
It looks like Apple is finally ready to bring Messages up to speed in macOS 10.15, adding effects such as as confetti and fireworks and proper support for stickers. It’s unknown whether Apple will go so far as to extend the iMessage App Store to the Mac, and if so, whether developers would need to specifically update their apps to work with Messages on macOS. Either way, this seems like another area in which Marzipan could be a very big help.
