Document QtWebEngine support for OS X 10.9

09:33 <alcroito> The-Compiler: Afaik webengine 5.7 is not going to be officially supported  for 10.9 anymore
09:36 <alcroito> The-Compiler: Also without the build log, it's kind of a guessing game what went wrong
09:37 <alcroito> The-Compiler: My initial guess would be that if the build is done with the 10.10 sdk shipped with xcode 6.2, then it will not be enough, because it requires a newer 10.10 sdk
09:38 <The-Compiler> alcroito: yeah, I just mentioned that guess as well - seems like 10.10.3 is required?
09:38 <alcroito> The-Compiler: Yes, which ships minimum with xcode 6.3, which is not supported on 10.9, which is why we will probably not support it either
09:39 <The-Compiler> alcroito: FWIW http://doc.qt.io/qt-5/qtwebengine-platform-notes.html#os-x says "On OS X, Xcode version 5.1 or later on OS X 10.9 or later is required." for 5.7 which implies that'd work
09:39 <alcroito> The-Compiler: That is outdated, and we will have to update it. We discovered that 10.9 won't work fairly recently
09:40 <alcroito> The initial assumption was that 10.10.3 sdk would be shipped with xcode 6.2, but that's not the case.
09:41 <The-Compiler> So homebrew would have to drop QtWebEngine for 10.9 with Qt 5.7?
09:41 <alcroito> You can of course take the 10.10.3 from a newer xcode, and build with the older one, but that might not work forever
