Description

In Homebrew, we were trying to build Qt6 on macOS 15.0 Sequoia (RC) with a deployment target of 15.0

The build failed due to use of obsolete APIs in QtBase Cocoa Platform Plugin:

This was seen building 6.7.0, but should impact latest development code: https://github.com/qt/qtbase/blob/dev/src/plugins/platforms/cocoa/qcocoascreen.mm#L550
