Apple is upgrading iPhone Mirroring in macOS 27 Golden Gate with three significant enhancements that improve daily workflow for Mac users. The window resizing feature eliminates the previous limitation of only three preset sizes, allowing users to adjust the mirroring window dynamically with any iOS 27-compatible applications.

Control Center access now works through CMD+4 keyboard shortcut or the View menu, addressing a longstanding gap in functionality. DRM video support resolves the frustrating black screen issue that plagued protected content playback, making streaming services accessible during mirroring sessions.

These updates strongly suggest preparation for the rumored foldable iPhone Ultra, expected later this year, as flexible display support requires adaptive window management. Currently limited to native Apple apps, third-party support will arrive as developers roll out iOS 27 updates throughout the year.

The new iPhone Mirroring icon rounds out the visual refresh, bringing the app in line with other updated Apple stock applications. For users who rely on cross-device workflows, these changes eliminate major pain points in what was already a useful productivity bridge between Apple's ecosystems.
