I wrote a cross platform application and I distributed it successfully for Windows and Linux (and tested them on "clean" virtual systems, with no other additional software and/or libraries installed).
I have already compiled my application on my Mac computer, but I don't know if my application will work on other Mac computers.
I don't have two Macs, also, (as far as I know) it's difficult to install Mac OS X on a virtual machine with "legal" discs or without having to perform a process similar to building a Hackintosh, this means that I cannot test my app on a virtual machine (in VirtualBox).
So may question would be: Is there any way of making sure that my application will actually run on other Mac systems (without the need of using another computer)?
As an additional note, I wrote my application by using the Qt framework.

You can use a VM running on your Mac. I've done this with Parallels: http://kb.parallels.com/en/112121
If I understand correctly, you have a Mac on which you have compiled the app but you want a clean environment to test deployment. So if you set up a VM on that same Mac that you compiled on, you will have a clean OSX to test with.
