Are all features available on all recent Macs (Intel + M1)? iirc there were some features that there were some exclusive M1 features to come, but also overheard rumors that they'd still roll out on "old" Intel Macs. Edit: Apparently some features are indeed M1 only. Those features are - portrait mode in FaceTime - apparently the new Apple Maps design - the interactive globe Seems like the most important features (for me it's livetext) are available on both architectures.
