Apple releases macOS Big Sur 11.3 with M1 optimizations, updated controller support, ability to change window size of iPhone and iPad apps on Macs, and more

Context & Ripple Effects
Big Sur began as a broader Mac interface overhaul, with a redesigned Control Center and Notification Center arriving in the initial release. On M1 Macs, Big Sur 11.1 then let iPhone and iPad apps with fixed windows enter full screen, rather than making their windows resizable.
Version 11.3 advances that M1-era app compatibility path by adding resizable iPhone and iPad app windows alongside M1 optimizations and updated controller support. The change matters because it addresses a specific desktop-use constraint in Apple’s cross-device app catalog.
First-order effects
- M1 Mac users can resize compatible iPhone and iPad apps instead of relying on the earlier full-screen option for fixed-size app windows, making those apps fit more naturally alongside Mac software.
- Apple expands the practical value of its M1 Mac app environment with system-level optimization and updated controller support.
Second-order effects
- Developers whose iPhone and iPad apps run on Macs face less friction in serving Mac users through the existing mobile-app catalog, rather than depending solely on a separate fixed-window experience.
- Controller support makes the Mac environment more accommodating for games and other controller-oriented iPhone and iPad apps, increasing the relevance of mobile software on M1 Macs.
Third-order effects
- If Apple continues removing desktop-use limitations from mobile apps on Macs, the distinction between its Mac and mobile software catalogs will increasingly be defined by interface adaptation rather than separate distribution paths.
The trend: Apple is using M1-era macOS releases to make iPhone and iPad software more usable on Macs while retaining Mac-specific interface capabilities.
