That's not what I'd call integration testing. Integration testing tests the interfaces between your classes/modules/processes. And that's a completely different set of tests from your unit tests.

Virtual machines, eg VirtualBox. You can install all of the required OS on a single physical machine (assuming the same hardware of course). For example, on my Linux Mint box I have 2 versions of Windows(XP and Win 8.1) plus Ubuntu and Mandriva Linux virtual machines ready to run. It only takes a few seconds to start/stop each one. It might be possible to run an intel based MacOS in a virtual machine too but I've not tried that and limit my Apple testing to my ancient G3 based iBook... > the same.
