I guess it depends on how the OS uses the drive, I suspect that the Macbook running Vista will be the same as any PC running Vista. From the articles that I read it was multiple small random writes that kills the OCZ( and other Jmicron based) drives. If the OS does not do lots of random writes then there will be no problems
It's not just about the OS - it's the nature of the applications that you are running - even without the load placed on the drive by the OS the current MLC drives struggle with multiple different operations involving random read/writes. So even if you used MacOS, were you to try downloading, browsing, and playing music all at the same time you would be in for a nasty suprise according to current reports.
