I don't personally use Apple products, but I do have some trust that they can get font rendering right. The browser window I'm looking at right now is a subset of my monitor, and could be considered a 'virtual display', but subpixel rendering works in that region. There's no reason other than laziness or lack of vertical integration that it wouldn't work in a virtual environment.
