It has let problermlos via the USB interface to connect with the iMac and is also recognized directly in the Control Panel. The lack eject button I see as no disadvantage, since the current iMac an eject button is integrated directly on the keyboard - this the LW can be easily operated.
The LW is a bit noisy in operation - but I do not feel this is more disturbing. The reading and writing speed for DVD and CD's fine.
Buy recommendation.
