    Hey there,

    I tried to install Qt 4.8.3 (Creator 2.6.2) with on my Mac (10.8.2 Mountain Lion). Running projects which ran on other Macs failed to built. So, after a while I pretty fucked up everything on my system.

    I have no maintenance tool anymore, and don't know why. I don't have the python script neither. Please, I am desperate; How can I uninstall Qt for a clean re-install?

    I really like to work with Qt.
    Thanks in advance!

    Rob

      Hello,

      How did you install Qt ?

        Hey SGaist!

        On this page, I clicked the DOWNLOADS tab, downloaded the Mac Version of 4.8
        Qt libraries 4.8.4 for Mac (185 MB) and debug libraries (480 MB) and installed it.

        As I said (didn't know about the ###), I really messed it up, while not being able running projects. So I tried 5 then 4.8, and I was able to uninstall both again with the python script as well as the maintenance tool. But now, nothing is available anymore...

        EDIT:
        Even the examples aren't there anymore.

          Hello. Did you tried to have a look (via xterm) in the subfolders of /usr/ ? or use the locate command (or find) to try to find one file present in qt (e.g a source file present in qt) ?

          Maybe you will find the path of your qt install by this way ?

            There is some in /System/Library/Frameworks/QTKit.framework. But does this help me? I guess just remove these files isn't really a clean uninstall, isn't it?

              Don't touch one ! It's for QuickTime (QT) not Qt (Yes casing is really important here)

                Have a look in your /usr/local/ folder, maybe you will find the qt install folder (by default my qt install is there (mac os x 10.7 & qt5). If you find it there, remove the folder by using the command rm -rf yourQtFolder

                and as SGaist said, be carefull with casing. And look only in /usr/local (if you used the binaries for your install as you said before, the setup floder should be there).

                  Haha, thanks for mention that! But any suggestions yet for the actual problem?

                  I just saw, that there is also content in /Applications/Qt Creator.app/Contents/...
                  Any chance, that this is helpful?

                    No, it's juste Qt creator app. you can use a soft like AppCleaner to remove it. For Qt itself, try what i suggested on my last post

                      I just looked. In the /usr is nothing like Qt and no folder 'local'.

                      Since Creator is running but working, isn't it possible, that all files are removed allready but the ones in /Application/...

                        Murphy is gone!

                        Thread can be closed. I just removed the files in /Application/... cause they seemed to be the last one. Reinstalled Qt 5 and it runs. Thanks to all of you.
