I recently purchased a Retina MacBook Pro 13 (2013) and installed Windows 8.1 with EFI on a partition using bootcamp. Everything in it appears to work near perfectly with a single exception. Whenever I close the lid to put it into sleep mode, it will not resume and I am forced to trigger a hard reboot with the power button. As I'm coming from a Windows machine I really would prefer to stick with Windows and having the sleep functionality is very important to me. I've looked around and haven't been able to find a solution, so I'm hoping that it isn't simply to "wait until Apple releases new drivers". Thanks in advance for any suggestions on fixing this.
