I change the kit to my "Qt 5.3.1" installation. Everything compiles fine. The issue is that QtCreator can not seem to locate any Qt Header. There is a red squiggly line under #include <QtCore/QObject> and then none of the syntax highlighting works after that. I

When I've seen this with qmake projects it's been because the .pro file was valid enough to be parsed correctly by qmake, but had errors in it that caused Creator to fail to parse it. Tools -> C++ -> Inspect C++ Code Model might be useful (or it might cause Creator to unceremoniously crash: save everything first).

There are also some environment variables you can set to get more diagnostics, if the code model window doesn't have anything useful.

I've not seen debugging work usefully on OS X for an age, regardless of Qt version.
