Hi. I have a2009 (5,1 Flash) 6-Core cMP. I have OSX on a Sandisk 120GB SSD in Bay 1, Windows 10 on a Sandisk 120GB SSD in Bay 2. A 1TB HDD in Bay 3 and the original shipping 640GB HDD in Bay 4. In OSX, I cam use BootChamp to boot into my Windows 10 installation. But in Windows 10 (Also tried Windows 8), when I click on the "Restart to OSX" option in the taskbar, it only reboots to Windows. To get back to OSX, I have to boot holding the Option key and select my OSX drive. Anyone have a fix for this?
