New 27" iMacs With 3TB Fusion Hard Drives Unable to Use Boot Camp
Apple’s 27” iMacs, while powerful and beautiful, possess a rather significant snafu involving Apple’s new 3TB Fusion Hard Drive.
Apple has disclosed rather quietly that any 27” iMac outfitted with a 3TB Fusion Drive will not be able to utilize Boot Camp. At all. Apparently adding the $400 option to a build-to-order iMac prevents business users and others who depend on the Windows platform from accessing Microsoft's OS without the aid of virtualization software like Parallels and VM Ware.
Apple has yet to explain why the 27” iMacs with 3TB Fusion Drives can not utilize Boot Camp, but their smaller 2TB and under hard drives can. User’s have pointed out that it’s likely a limitation of 3TB drives in combination with the BIOS utilized in Boot Camp. Throwing in the 128GB SSD as part of the Fusion Drive is just the icing on the cake.
Whatever the reason Apple should be actively notifying users purchasing made-to-order iMacs with 3TB drives that they will not be able to utilize Boot Camp. At least as of now. Apple has left the door open for future updates adding support.
