As more interviews with Apple's software engineering chief Craig Federighi surface, we learn more about why iPadOS's Stage Manager feature is limited to the iPad with the M1 chip.
Federighi was asked if Apple tried to make Stage Manager compatible with iPad models without the M1 chip. Federighi said that Apple did some early testing of the feature on other iPads, but they weren't satisfied with the experience they got.
He said that it became apparent early on that they couldn't deliver the experience that they were designing for with them. We don't want to hold back the definition of a new experience and not create the best foundation for the future in that experience. We could only do that if we built on the M1.
Federighi said in an interview with Matthew Panzarino that the M1 chip's performance ensures that all apps in Stage Manager are instantly responsive.
Apple stated that Stage Manager requires large internal memory, incredibly fast storage, and flexible external display I/O, all of which are delivered by iPad with the M1 chip.
The M1 iPad Pro has up to 16 gigabytes of RAM and a Thunderbolt port, while the previous-generation iPad Pro only has 6 gigabytes of RAM and a port. The M1 iPad Pro has faster storage and performance than the previous model. The iPad mini, entry-level iPad, and older iPad Pro models are not compatible with the fifth-generation iPad Air.
Stage Manager is a new feature in iPadOS 16 that allows users to change the size of iPad apps. Users can use up to four apps on the iPad and up to four on the external display at the same time with the feature. Stage Manager can be used to keep windows front and center.
