Restart your Mac and hold down the Option key.DO NOT do this unless you can afford to lose the entire contents of the hard drive on that computer. Very important: This will wipe the contents of the hard drive on the computer you perform this on. (We’ll try this in a future episode.) Start your Mac using a NetRestore image
Obviously, a NetBoot image with only a base installation of the operating system isn’t very useful, but if you create a fresh install of the OS and set user accounts up that have Home Folders stored on a network server you guarantee that every time you restart your Mac you’ll have a fresh copy of the OS.
This is your Mac letting you know that it is starting up from a NetInstall server.īecause we created this image from a basic installation of the OS with a couple of apps added to your Applications folder, when your Mac completes the startup process you sill see the welcome screen you usually see when starting a new Mac for the very first time. You should now see an Apple logo with a spinning globe beneath it.
