 - Only macOS is supported as the host platform
 - Xcode and developer tools must be installed. Note, that usually some time is needed for the Appium team to pick up with the support of the most recent Xcode versions, especially beta ones (check [Xcode version support](#xcode-version-support) section below).
 - Connected real devices must be trusted, added to your developer profile and configured properly along with WebDriverAgent signing. Read [Real devices](#real-devices) section _carefully_ to set them up properly before running your tests.
-    - Starting from iOS/iPadOS version iOS/iPadOS 16 real devices require enabling of _Developer Mode_ option in _Settings -> Privacy & Security_
+- iOS/iPadOS 16 real devices require enabling developer mode. Please read [Enabling Developer Mode on a device](https://developer.apple.com/documentation/xcode/enabling-developer-mode-on-a-device) for more details. `devmodectl streaming` CLI on macOS 13+ and installing development signed apps also help enabling the mode.
 - Consider using earlier releases of the driver (check [Xcode version support](#xcode-version-support) section below) if it is necessary to test iOS versions older than the current iOS major version minus one on real devices. Also, it is highly recommended to always use the same major version of Xcode SDK, which was used to build the particular iOS/tvOS version on your real device under test (for example Xcode 11 for iOS 13, Xcode 12 for iOS 14, etc).
 - Web views must be debuggable in order to test them. If it is not possible to connect to your web view(s) using [Safari remote debugger](https://appletoolbox.com/use-web-inspector-debug-mobile-safari/) then XCUITest won't be able to connect to them as well.
 - Since version 3.33.0 (included into Appium 1.20.0+) of XCUITest driver the [Carthage](https://github.com/Carthage/Carthage) dependency *is not needed anymore*. Prior to that version it was required and could be installed using [brew](https://brew.sh/): `brew install carthage`.
