Qt5.6 removed QTWebKit which hifi depends on. Before we complete the migration listed in https://wiki.qt.io/Porting_from_QtWebKit_to_QtWebEngine the build instruction need to tap into qt55 in historical brew versions.

Please read the general build guide for information on dependencies required for all platforms. Only OS X specific instructions are found in this file.
###Homebrew Homebrew is an excellent package manager for OS X. It makes install of all High Fidelity dependencies very simple.
brew tap homebrew/versions
brew install cmake openssl qt55
We no longer require install of qt5 via our homebrew formulas repository. Versions of Qt that are 5.5.x provide a mechanism to disable the wireless scanning we previously had a custom patch for.
###OpenSSL and Qt
Assuming you've installed OpenSSL or Qt 5 using the homebrew instructions above, you'll need to set OPENSSL_ROOT_DIR and QT_CMAKE_PREFIX_PATH so CMake can find your installations. For OpenSSL installed via homebrew, set OPENSSL_ROOT_DIR:
export OPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2d_1
For Qt 5.5.1 installed via homebrew, set QT_CMAKE_PREFIX_PATH as follows.
export QT_CMAKE_PREFIX_PATH=/usr/local/Cellar/qt5/5.5.1_2/lib/cmake
Not that these use the versions from homebrew formulae at the time of this writing, and the version in the path will likely change.
###Xcode If Xcode is your editor of choice, you can ask CMake to generate Xcode project files instead of Unix Makefiles.
cmake .. -GXcode
After running cmake, you will have the make files or Xcode project file necessary to build all of the components. Open the hifi.xcodeproj file, choose ALL_BUILD from the Product > Scheme menu (or target drop down), and click Run.
If the build completes successfully, you will have built targets for all components located in the build/${target_name}/Debug directories.
