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)
