# How to resize iPhone Mirroring and open Control Center in macOS 27

*Drag a corner to resize the window, and press Command-4 for Control Center*

**Key points**

- In macOS 27, you can drag a corner of the iPhone Mirroring window to resize it; Command-9 returns it to iPhone size.
- Apps such as Mail, Messages and Calendar show more information when the window is made wider.
- Command-4 opens the iPhone's Control Center in iPhone Mirroring on macOS 27 or later.

macOS 27 Golden Gate, released on 14 September, makes two practical changes to iPhone Mirroring: the window can now be resized freely, and Control Center can be opened from the keyboard. Here is how both work, according to Apple’s [iPhone Mirroring support guide](https://support.apple.com/en-us/120421).

## How to resize the iPhone Mirroring window

Until now, the window could only switch between three preset sizes. Those presets remain: choose Larger, Smaller or Actual Size from the View menu, or press Command–Plus sign (+), Command–Minus sign (–) or Command-0.

In macOS 27 or later, you can also drag a corner of the window to any size you like. Some apps, such as Mail, Messages and Calendar, are designed to show more information when you make the window wider, Apple says. To go back to the standard iPhone size, click the iPhone size button in the iPhone Mirroring toolbar or press Command-9.

## How to open Control Center

Press Command-4 while iPhone Mirroring is active to open your iPhone’s Control Center. This shortcut requires macOS 27 or later. It joins the existing shortcuts: Command-1 for the Home Screen, Command-2 for the App Switcher and Command-3 for Spotlight.

## Requirements

iPhone Mirroring needs a Mac with Apple silicon or the Apple T2 Security Chip, an iPhone set up with a passcode, and both devices signed in to the same Apple Account with two-factor authentication, Bluetooth and Wi-Fi turned on. The iPhone must be locked and near the Mac. The feature is still unavailable in the European Union.
