Qt 5.6 / 5.7 Mac installer not launching


  • I usually use Qt on Windows, and now I'm trying to set up a Mac development machine.
    I am unable to install Qt on my MacBook Pro. I have tried using the macOS web installer that the most recent Qt download page directs me to (open source). A file called qt-unified-mac-x64-2.0.3-online.dmg is downloaded, which contains a .app of the same name, but when I try to open that file, a dialog says that the file cannot be opened "because of a problem." I have also downloaded the offline installer, which is a .app within a dmg, but double-clicking that .app gives a similar error message.

    My MacBook Pro has Mac OS X Version 10.6.8, with an Intel Core 2 Duo.
    I have Xcode Version 3.2 (1610) installed, with (I am pretty sure) command line Xcode enabled/installed. The MacBook itself is about 4.5 years old. (Model Identifier MacBookPro5,5)

    Any tips would be appreciated. I'm not super experienced with Macs. Thanks.
    Aaron

    @aampere Current MacOS version is 10.12.1 and XCode > 4.0 (don't know exactly). I don't think with such an outdated environment you will be able to use Qt. Why don't you update your OS and XCode (both are free)?

    Hi and welcome to devnet,

    You need at least 10.8 to develop with the current Qt versions. Xcode 7.3.1 works pretty well for that otherwise the current version is 8.1.

  • Thank you very much, both of you!
    Updating to OS X 10.11.6 (El Capitan) and updating XCode (to 8.1, I believe) fixed this issue for me.
    It's an older laptop, and I maxed out its automatic updates without realizing I needed to get further OS X updates from the App Store.

    Im using Mac OS like you, but im using OSX 10.11.3 el capitan and Xcode 7.3.1, installed without prorblms, the only downside i have found is a problem with the include paths, but once you add them you should be good to go
