You should not need to change this default, but if needed you can increase it in your project file: Qt expresses the deployment target via the QMAKE_MACOSX_DEPLOYMENT_TARGET qmake variable, which has a default value set via the makespec for macOS.

If the binary is launched on a macOS version below the deployment target macOS or Qt will give an error message and the application will not run. In theory this would allow running your application on every single macOS version released, but for practical (and technical) reasons there is a lower limit to this range, known as the deployment target of your application. When the binary is run on a macOS version lower than the SDK it was built with, Qt will check at runtime whether or not a platform feature is available before utilizing it.

14.sdk Target PlatformsД«uilding for macOS utilizes a technique called weak linking that allows you to build your application against the headers and libraries of the latest platform SDK, while still allowing your application to be deployed to macOS versions lower than the SDK version. app /Contents /Developer /Platforms /MacOSX. I can only guess why they did that, suspecting that the intend was to have Xcode in the location where it belongs: It's and application, so it shall be accessible under /Applications./Applications /Xcode. The error has historical roots - Qt still tries to access Xcode in the path /Developer/Xcode.app/Contents/Developer - but Apple has moved the installation to /Applications/Xcode.app/Contents/Developer. Those who never had Qt installed before most likely encounter the error Xcode is not installed in /Developer/Xcode.app/Contents/Developer when trying to build a project - The solution is easy to find, but added here for completeness. Fixing Xcode is not installed in /Developer/Xcode.app/Contents/Developer

Click on Install and Xcode starts downloading and installing the Command Line Tools.ДЄfter the installation has completed you can install Qt flawlessly with the corresponding installer. You can see an item Command Line Tools in the List. You can find them in the Xcode status bar, under Xcode -> Preferences. Start Xcode - Make sure that you have installed the latest and greatest version, and applied all the updates: Whatsoever, installing the Command Line Tools is fairly easy if you are already familiar with Xcode, and for those who are new to Xcode it is not that big kind of a deal, either.

What surprised me the most is that this is nowhere mentioned if you look at the Qt download page - Not a single word, even though many developers will stumble upon the sane issue. Fixing the IssueДЄfter a lot of research and talking to a coworker who happens to be some sort of a Qt Guru I eventually found out the problem: Qt access clang via the Command Line Tools, and these tools are not shipped with every version of Xcode. The trouble starts when you try to compile your code: It won't, because Qt uses clang via the Xcode Command Line Tools. If that error occurs, you can still run Qt based apps on your Mac and the Qt Creator will still start as nothing happened. In addition to that they attempt to configure clang, a C++ compiler, and a failed configuration attempt leads to the already mentioned error message. The setup installs the Qt Creator and the Qt binaries. I needed quite a bit of time and a hint from a colleague to find out what was wrong, and since not everyone has the luck of having a colleague who happens to know the answer to most of the problems Qt offers you, I decided to share the solution to the mysterious error clang install_name_tool failed error - Which is as easy as big the surprise is when the error hits you for the first time. I want to explain what clang is, and why its absence (yes, that error message shall indicate its absence - I was surprised too!) causes the installation to fail. This is certainly applicable if you want your Qt IDE to run on Windows, but when it comes to OS X you are very likely to run into the installer error clang install_name_tool failed. Installing Qt is (usually) an easy task: Download the installer, let it do its duty and done you are.
