Apart from the innovations that we know little by little OS X El Capitan, we also find others but has not had much impact for certain users if it can be interesting. I mean the change suffered in Boot Camp, not because the installation wizard of Windows has changed dramatically, but because now users who want to install the system from Microsoft on your Mac will not have the need to create a partition on a USB stick, but that can be installed natively.
There used to plug in a USB memory and Boot Camp Assistant copied the installer from the ISO image in the memory unit and then download and configure the necessary Windows drivers in the location where the installer for the hardware is would find that Mac specific. Captain makes it simple and just have to select the ISO and the amount of space we want to occupy the Windows partition and click on install, simple as that.
But then, where is the partition installer of Windows ?, very simple, OS X El Capitan apart from creating as did previous versions of the system, its own Boot Camp partition to install Windows, now also creates another partition called OSXRESERVED will occupy 8Gb in FAT32 format and placed after the recovery partition and before the Boot Camp partition.
Now the new Macs have the ability to detect this partition as if it were an installation media through the EFI (Extensible Firmware Interface) as if it were a USB flash drive or DVD to perform the installation. Once the partition is removed OSXRESERVED without trace or occupy space. Of course, it should be clear that not all Macs are compatible because they do not have this feature. In the following list we leave compatible equipment
- Mac Pro
- MacBook Air 13-inch
- MacBook Air 11-inch
- 13-inch MacBook Pro (Early-mid 2015)
- 15-inch MacBook Pro
The iMac does not appear, something strange given me the latest models feature the latest versions of EFI, although these versions may even be the last are not equally compatible.(Source: Twocanoes)
