macOS (previously known as OS X or Mac OS X) is Apple's operating system for the Mac line of computers. It's a UNIX platform, based on the Darwin kernel, and behaves largely similar to other UNIX-like platforms. The main difference is that X11 is not used as the windowing system. Instead, macOS uses its own native windowing system that is accessible through the Cocoa API.
To download and install Qt for macOS, follow the instructions on the Getting Started with Qt page.
Supported Versions
When talking about version support on macOS, it's important to distinguish between the build environment; the platform you're building on or with, and the target platforms; the platforms you are building for. The following macOS versions are supported.
Then, under the “MAC OS:” section, click on the “.tgz archive” file (green arrow in the photo above). This is the G’MIC-QT plugin’s download file for MAC. Clicking this link will download the file to your Downloads folder on your computer. Step 2: Extract the Download File.

Unzip it to whatever folder you think is most convenient. Open Qt Designer using any of the available shortcuts in your computer. By default, Qt Designer will show the New Form dialog on opening. Choose Dialog with Buttons Bottom from the template forms list and press Create. Qsynth is a fluidsynth GUI front-end application, written in C around the Qt framework, using Qt Designer. Eventually it may evolve into a softsynth management application allowing the user to control and manage a variety of command line softsynths. To use QtCreator and the Slicer designer plugins, a possible option is to build QtCreator against the installed Qt libraries. See discussion on the mailing list. Mac with Homebrew. As an alternative to the binary, you can install QT 4.8.7 with homebrew on mac 10.12: brew tap cartr/qt4 brew tap-pin cartr/qt4 brew install qt@4 brew install qt.
Build EnvironmentQt Creator Mac Download
The build environment on macOS is defined entirely by the Xcode version used to build your application. Xcode contains both a toolchain (compiler, linker, and other tools), and a macOS platform-SDK (headers and libraries). Together these define how your application is built.
Note: The version of macOS that you are running Xcode on does not matter. As long as Apple ships a given Xcode version that runs on your operating system, the build environment will be defined by that Xcode version.
Xcode can be downloaded from Apple's developer website (including older versions of Xcode). Once installed, choosing an Xcode installation is done using the
xcode-select tool.
You can inspect the globally selected Xcode installation using the same tool. Soundcloud app for mac.
The
xcrun command can then be used to find a particular tool in the toolchain.
or show the platform SDK path used when building.
Target Platforms
Building 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. 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.
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. 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.
Qt expresses the deployment target via the
QMAKE_MACOSX_DEPLOYMENT_TARGET qmake variable, which has a default value set via the makespec for macOS. You should not need to change this default, but if needed you can increase it in your project file:
Note: You should not lower the deployment target beyond the default value set by Qt. Doing so will likely lead to crashes at runtime if the binary is then deployed to a macOS version lower than what Qt expected to run on.
By always building against the latest available platform SDK, you ensure that Qt can take advantage of new features introduced in recent versions of macOS.
For more information about SDK-based development on macOS, see Apple's developer documentation.
Opting out of macOS behavior changes
One caveat to using the latest Xcode version and SDK to build your application is that macOS's system frameworks will sometimes decide whether or not to enable behavior changes based on the SDK you built your application with.
For example, when dark-mode was introduced in macOS 10.14 Mojave, macOS would only treat applications built against the 10.14 SDK as supporting dark-mode, and would leave applications built against earlier SDKs with the default light mode look. This technique allows Apple to ensure that binaries built long before the new SDK and operating system was released will still continue to run without regressions on new macOS releases.
Mac Install Qt
A consequence of this is that if Qt has problems dealing with some of these macOS features (dark-mode, layer-backed views), the only way to opt out of them is building with an earlier SDK (the 10.13 SDK, available through Xcode 9). This is a last-resort solution, and should only be applied if your application has no other ways of working around the problem.
Pyqt Designer MacArchitectures
By default, Qt is built for x86_64. To build for x86_64h (Haswell). use the
QMAKE_APPLE_DEVICE_ARCHS qmake variable. This is selectable at configure time:
QMAKE_APPLE_DEVICE_ARCHS can also be specified as a space-delimited list in order to build for multiple architectures simultaneously:

On the command-line, applications can be built using
qmake and make . Optionally, qmake can generate project files for Xcode with -spec macx-xcode . If you are using the binary package, qmake generates Xcode projects by default; use -spec macx-gcc to generate makefiles. For example:
Configuring with
-spec macx-xcode generates an Xcode project file from project.pro. With qmake you do not have to worry about rules for Qt's preprocessors (moc and uic) since qmake automatically handles them and ensures that everything necessary is linked into your application.
Qt does not entirely interact with the development environment (for example plugins to set a file to 'mocable' from within the Xcode user interface).
The result of the build process is an application bundle, which is a directory structure that contains the actual application executable. The application can be launched by double-clicking it in Finder, or by referring directly to its executable from the command line, for example,
myApp.app/Contents/MacOS/myApp .
If you wish to have a command-line tool that does not use the GUI for example,
moc , uic or ls , you can tell qmake to disable bundle creation from the CONFIG variable in the project file:
Deploying Applications on macOS
macOS applications are typically deployed as self-contained application bundles. The application bundle contains the application executable as well as dependencies such as the Qt libraries, plugins, translations and other resources you may need. Third party libraries like Qt are normally not installed system-wide; each application provides its own copy.
A common way to distribute applications is to provide a compressed disk image (.dmg file) that the user can mount in Finder. The deployment tool,
macdeployqt (available from the macOS installers), can be used to create the self-contained bundles, and optionally also create a .dmg archive. Applications can also be distributed through the Mac App Store. Qt 5 aims to stay within the app store sandbox rules. macdeployqt (bin/macdeployqt) can be used as a starting point for app store deployment.

Note: For selling applications in the macOS App Store, special rules apply. In order to pass validation, the application must verify the existence of a valid receipt before executing any code. Since this is a copy protection mechanism, steps should be taken to avoid common patterns and obfuscate the code that validates the receipt as much as possible. Thus, this cannot be automated by Qt, but requires some platform-specific code written specifically for the application itself. More information can be found in Apple's documentation.

I am very new (to Python, Designer, etc) and having a problem installing PyQt DESIGNER. I installed Python 3.6 I also installed PyQt5 using Windows command window and pip3. Everything worked fine (it said it was successful). Since PyQt - DESIGNER did not show up in my Windows Start Menu (like in a normal download from a web with an exe file), I am guessing I need to install DESIGNER separately. After searching various forums, I tried installing DESIGNER using 'pip3 install PyQt5-tools' in the Windows command window and got 'Could not find a version that satisfies the requirement PyQt5-tools (from versions:) No matching distribution found for PyQt5-tools.'
I also downloaded something called a wheel -- pyqt5_tools-5.7.dev9-cp35-none-win_amd64.whl (md5) -- from Python software foundation. It is in my download bucket, but I do not know how to 'run' it -- like a traditional downloaded exe file. So what do I do now? I want to download QT5-DESIGNER so that it shows up in my Windows Start Menu. Again, I am new so please be patient. Thanks I figured out how to download the wheel mentioned above using pip -- but it says ' the wheel is not a supported wheel on this platform' -- anyone know what that means? Should I give up on PyQt5 and use PyQT4? Comments are closed.
