Apple has launched a replacement program for certain iMac models with 3TB hard drives. If you bought a 27-inch iMac with a 3TB hard drive between December 2012 and September 2013, you might be eligible for a free replacement hard drive.

One frustrating aspect of Boot Camp is that it doesn’t support hard drives larger than 2.2TB. That means that if you custom install a larger hard drive, or order a new iMac with a 3TB hard drive, you won’t be able to use all of that space to run Windows. Luckily, there’s now a partial fix, thanks to the developer of Winclone.
