NetBoot provides modern Mac® computers with the option to boot directly from a shared network volume instead of a local drive or data medium. This is particularly relevant for recovering from a damaged macOS® installation or for initial setup of new devices. This functionality is based on the firmware of compatible Mac computers that enables them to boot from network drives or from a system image at a storage location that is accessible for the Mac. NetBoot can also provide new Mac computers with a customized installation file to roll them out in the organization.
- Mac OS X Server comes with the Network Image Utility, which can easily build a NetBoot image of a generic Mac OS X installation. This utility also creates all of the needed support files in the.
- Building a bootable image from a CD is and entirely different process. Bootable CD's are built in a similar fashion as NetBoot images to save space on the CD. What we need to do is locate the data we need on the CD and build our Netboot image from there. This process requires the use of Terminal to get the necessary parts.
It shouldbe noted that some current Mac models do not support NetBoot anymore.
How toenable NetBoot for Microsoft SCCM
Create NetBoot images in System Image Utility on Mac. A NetBoot network image allows you to start several Mac computers over an Ethernet network using the NetInstall service of the Server app. Workflows that create custom NetBoot network images can use a bootable volume, a disk image (of a bootable volume), or a macOS install app as the source. So, WDS is not going to work at all, even if you could bootp to it, is can't host a netinstall image or a netboot image and you'll need apple tools to even attempt to block copy an OS image to it. I also wouldn't invest much in imaging a Mac either, it is likely going away. Create the new iPXE image and embedding the ipxe.efi file by running the following command: make bin-x8664-efi/snponly.efi EMBED=ipxe.efi Make sure to copy snponly.efi to your TFTP root, restart the services and the iPXE shell should now automatically load.
Parallels® Mac Management for Microsoft® SCCM allows organizations toutilize the NetBoot functionality within an SCCM environment. Only a few prerequisitesneed to be met to make NetBoot work with SCCM. The IT team needs to install theNetBoot component on a server for it to assume the role of a distributionpoint. All other requirements are explained in detail in the Administrator’s Guide (PDF). Dynamic Host ConfigurationProtocol (DHCP) forwarding needs to be activated if the NetBoot server and thetargeted Mac clients reside in different subnetworks.
Afterinstallation, the Parallels NetBoot Configuration Wizard will runautomatically. A small number of steps need to be configured here. Afterentering the SCCM environment’s SMS provider and opening a user account for theNetBoot server, the IT team needs to create a directory for the image files.
The last step for the IT team is to create a NetBoot image of macOS that the Mac devices can boot from. The Parallels tool PmmOsdImageBuilder helps with this. The IT team will need a reference Mac computer for the software tool to mirror its operating system. The next step is to add this image in SCCM. This is done by navigating to “Software Library / Overview / Operating Systems / Operating System Images” and selecting: “Add OS X Image.” The last thing to do is to add this operating system instance to the distribution point.
