I picked up the new 13" rMBP yesterday in Sydney. It's already back at the Genius bar. The app store doesn't recognise that an update to OSX is required (it came with 10.8.1). The manual download of the 10.8.2 upgrade won't install because the 'hard disk does not have the correct requirements'. According to the Genius bar, it doesn't have the correct build for the machine. He's not even sure if there is a build for the 13 rMBP yet. This strikes me as something Microsoft might do. I am baffled as to how you can release and sell a product without having the latest OS software available on it. Has anyone else experienced this issue or is it just my laptop!?
