The Qt Creator official download site is When you go to this site, it should detect that your computer is running MacOS and recommend the installer 'Qt Online Installer for Mac OS'. Click the green 'Download' button to download the installer. 5) Run the Qt Creator installer. 1 Responsible: Qt Creator 54924 User ID: 501 Date/Time: 2020-01-08 22:12:42.699 +0100 OS Version: Mac OS X 10.15 (19A602) Report Version: 12 Anonymous UUID: 103F9158-D5E0-F1B8-BA89-222AB7C6F587 Sleep/Wake UUID: 3FB53B09-90D6-4FB8-AB3A-2D663E75701E Time Awake Since Boot: 170000 seconds Time Since Wake: 15000 seconds System Integrity. I just updated macOS to 10.14.4 as well as updating QtCreator to 4.9. Now I just get a blank screen when I open QtCreator. Any ideas on how I can fix it? Edit: It seems like 4.8 doesn't work either, but 4.7 does. It acts like the issue when you build usin.
How to use Qt Creator for software development on macOS without having to install Xcode
Justification
Qt refuses to install on macOS unless Apple's Xcode is installed beforehand.This is unfortunate because:
- Xcode is huge!
- The full IDE is a 5 GB download, and can occupy 20 GB+ of space on disk.
- Qt doesn't actually need the full IDE.
- Only Xcode's command line utilities are required for macOS application development¹.
- Developers may never actually use Xcode.
- They can program in Qt Creator, like they do in Windows and Linux.
Downloading and installing the command line utilities without Xcode saves time and bandwidth,and means that valuable SSD storage space is kept for better uses.
¹ I believe the full Xcode IDE is required for developing iOS apps with Qt(i.e. apps for iPads and iPhones)but I'm not sure about this as I'm not an iOS developer.
Instructions
Summary
- Install Xcode's Command Line Tools (i.e. not Xcode itself).
- Run in Terminal:
xcode-select --install
- Install Qt using the Online Installer.
- Download links:
- Open Source: https://www.qt.io/download-open-source
- Commercial: https://www.qt.io/download
- The installer will complain that Xcode is not installed.
- Keep clicking 'OK' until the message goes away permanently (after 12 clicks).
- Remember where you installed Qt (default location is
~/Qt).- If you used a different location then you will need to change subsequent commands accordingly.
- Make sure Qt Creator uses the correct C++ Compiler.
- Launch Qt Creator for the first time from the command line,with the location of the command line tools compilers in
${PATH}:PATH='$(xcode-select -p)/usr/bin:${PATH}' ~/Qt/Qt Creator.app/Contents/MacOS/Qt Creator
- Go to Qt Creator > Preferences > Build & Run > Kits and select a build kit (e.g.
Desktop Qt 5..). - Check that both the C compiler and the C++ compiler are:
clang(notgcc)- from the Command Line Tools (not the default compilers in
/usr/bin)
- Close Qt Creator.
- You can launch Qt Creator the normal way in future (e.g. via Spotlight).
- If your Qt version is older than Qt 5.9.2 then you need to update some QMake files.
Mac Install Qt
- Navigate to the directory
~/Qt//clang_64/mkspecs/features/mac - Make a backup copy of the following files before replacing them with newer versions from this git commit:
- Replace
sdk.prfwith this newer version. - Replace
default_pre.prfwith this newer version. - Make this change to the file
default_post.prf:- Find the line
cache(QMAKE_XCODE_VERSION, stash) - Replace it with
!isEmpty(QMAKE_XCODE_VERSION): cache(QMAKE_XCODE_VERSION, stash)
- Find the line
- Replace
All done!
Step-by-step
Step 1 - Download & install Xcode's Command Line Tools
Open a Terminal (press Cmd+Space and type 'Terminal') and enter this command:
Press the Return key to execute the command.
Step 2 - Download & install Qt and Qt Creator
Packages are available for MacPorts and Homebrew,but it's usually best to get it straight from the source:
The Office applications enter a reduced-functionality mode, which means that you can view documents, but you cannot edit or create new documents. Online services associated with the school email address—for example, Office Online and OneDrive—will no longer work. Download microsoft office on mac for free. Your eligibility may be re-verified at any time. When your Office 365 Education plan expires:.
- Open Source: https://www.qt.io/download-open-source
- Commercial: https://www.qt.io/download
The Online Installer is probably the best option for most people.
Tip: when you run the Online Installer it will prompt you to log in with Qt online credentials,but open-source users can skip this step without entering anything.
At a certain point during the install the following error message will appear:
You need to install Xcode version 5.0.0.Download Xcode from https://developer.apple.com/xcode
Press 'OK' or ESC to dismiss the dialog. It will come back again.Keep pressing 'OK' or ESC and the dialog will eventually go away for good!You have to dismiss the dialog a total of 12 times before you can continue.

Hint: Once Qt is installed you can delete the installer as you won't need it again.If you want to update or remove Qt you have to use the MaintenanceTool in the Qt directory.
Step 3 - Make sure Qt Creator uses the correct C++ Compiler.
Run this command in a Terminal windows to find out where Xcode's Command Line Tools are installed:
The result will probably be /Library/Developer/CommandLineTools,unless Xcode is installed. Whatever the result,you need to append '/usr/bin' to get something along the lines of:
Run Qt Creator once with this location stored in your ${PATH} environment variable:
Go to Qt Creator > Preferences > Build & Run > Kits and select a build kit (e.g. Desktop Qt 5..).
Check that the C and C++ compilers are the ones from the command line tools,not the default compilers in /usr/bin.Also check that clang is used for both compilers, not gcc.
Qt Creator will remember the locations of the compilers,so in future you can launch Qt Creator the normal way via Spotlight.
Step 4 - Update some QMake files (only necessary for Qt versions older than Qt 5.9.2)
The xcrun or xcodebuild utilities can be used to show where Xcode's Command Line Tools are installed,but only xcrun works when Xcode itself is not installed.
Qt 5.9.2 and later
Recent Qt versions use xcrun already, so there's nothing left for you to do!
Qt 5.9.1 and older
Older Qt versions try to use xcodebuild to find out where the utilities are installed.This fails with the following error message unless Xcode is installed:
Project ERROR: Could not resolve SDK Path for 'macosx'Error while parsing file . Giving up.
You need to tell QMake to use xcrun instead.
Open a Terminal and change directory to where the QMake files are stored.
Now copy and paste these new commands into the same Terminal windowto create backup copies of some files:
Press the Return key after the final command.
If that all went OK then run these commands to update the files:
