It is Universal binary... has been since like 10.4.5 I believe. I think the only reason they release PPC and Intel versions of the updates is because of hardware differences and patches to reflect that.

In any event, if you check the info on the system files they should show Universal Binary... that doesn't mean that you can clone an Intel machine to a PPC machine easily, but it is possible with some workarounds.

Hello,

Simply the fact that it is actually running on your system is proof enough. No other version of OS X would run on an intel mac. If you really want to check simply Get Info on any default system application like iChat or Preview and check under Kind. Mine for example only say PowerPC yours will say Universal.

able to run on intel mac doesn't proved is UB... in fact, I agreed that 10.4.5 may have codes that allow to run on it, consider how much R&D goes into Tiger and every version of OSX, I suspect a UB OSX require as much R&D as a new version. there is no documentations released from APPLE that 10.4.5+ is UB, anyone with links or information, please post it, thank.

Apple was maintaining a separate set of builds of Darwin for x86 for years. The kernel, the OS, has to be written and compiled for the hardware and cpu.

Applications are Universal Binary. The OS is probably not technically "UB" but allows for and supports Intel Core 2 Duo, and various flavors.

So there was years of 'R&D' and parallel development and testing going on.
