I was wrong about the timing of this relative to the shipping of 8800GT-equipped Mac Pros. This means that at least one of these is true about those Mac Pros:
- The have 10.5.2 on them already. (Most of them are still in transit. I don’t think anyone has reviewed or benchmarked them yet.)
- They shipped with the video driver installed separately on 10.5.1.
- They actually were delayed because of the 8800 GT’s short supply, and it’s complete coincidence that they waited almost until 10.5.2’s release that contained their driver.
And this is why it’s not wise to bet any money on Apple speculation.
