+Subject: [PATCH] Fix build error with macOS 10.13 SDK
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf8
+Content-Transfer-Encoding: 8bit
+
+Several of these variables/macros are no longer defined. We didn't
+validate the preconditions on iOS, tvOS, or watchOS, so no
+need to bother validating them on macOS either. Nor did we check the
+OSStatus result on any platform anyways.
+
+Task-number: QTBUG-63401
+Change-Id: Ife64dff767cf6d3f4b839fc53ec486181c176bf3
+(cherry-picked from 861544583511d4e6f7745d2339b26ff1cd44132b)
