Closest thing is PCSX2 on PC, which sorta works and sorta doesn't.
Needs a high clocked dual core cpu, high end graphics card and lotsa ram.
PS2 emulation won't reach mac for a few years at least, it hasn't really reached windows yet.
As for X360, well xbox emulation virtually doesn't exist, so you can forget about X360 emus for half a decade or so.
