|Qt Creator 2.6.0 Release [8.11.2012]|
For Linux you have to make the downloaded file executable and run it (e.g. "chmod u+x qt-creator-linux-x86-opensource-2.6.0.bin").
For Mac download and open the .dmg and copy the included Qt Creator.app to a location that you can access.
Please note that the source .zip packages are with Windows EOL (End of Line) termination. So, if you use that on Linux or Mac you want to unzip with the -a option to get proper EOL.
If you have any feedback on this package, please direct them to the bugtracker, or the Qt Creator mailing list.
Thanks, and happy coding!
The Qt Project
