Way to go Apple for producing updates to an old OS even when they made a new OS.

On a side note, this new push notification thing is great! First comment :D

My 2013 27" with the Fusion Drive applied the firmware update, despite the description saying "recommended for iMac with flash-only storage." Not sure if it'll affect mine or not, but either way, good deal. :)
