This service was stopped at the end of 2018. From 2019 on users have to use the Recovery partition to re-install macOS, see https://support.apple.com/en-us/HT204904 for details.
The information below is kept for historic reference only.
Installation of macOS is possible over the network from the NetInstall server - without the need to create any local installation volume. We provide NetInstall images for the supported version of Mac OS X, except for the .0 versions. Together with the operating system we also install the OCS Inventory Agent, see https://information-technology.web.cern.ch/services/fe/info/ocs-inventory-agent.

There are some people who want a fresh operating system and you can install it we are telling you the method. But what if you want to keep all your data and just reinstall the OS, that is also possible by just skipping this step and moving on to number 3.
Before starting the installation, it is recommended that you:
- check your latest backup,
- verify and if needed repair your disk using the 'Disk Utility'.
In most places, NetInstall will not work over Wifi (Airport). To avoid potential complications, it is recommended to turn off the Airport interface before doing a NetInstall.
To use the NetInstall service, connect your Mac to the CERN network, start the 'System Preferences' and select 'Startup Disk'. After a few seconds you should see the icon of the NetInstall image, as in the screenshot below. Select the icon corresponding to your image, and click the 'Restart…' button to restart your Mac.
When the Mac boots it will download and start the installer, and you will see the usual Installer interface. Select the target disk and make the package selection according to your preferences. It is highly recommended not to disable the 'Combo Updater' that is enabled in some of the install images.
If you do not see any NetInstall image in the list of proposed systems, you should check:
- that you have a proper network connection. This service is not supposed to work via wireless connections, or outside of CERN;
- that your Mac does work with the provided system versions. Non-Intel Macs do not work with 10.6 or newer, and will not show the NetInstall images.
If you do have a proper network connection and your Mac is supposed to work with one of the provided images, but you still don't get any of the images, please contact the ServiceDesk, describe the problem and provide the hostname and IP# of the Mac, as well as the 'Model Identifier' according to the 'System Information' app.
When you first start using a brand-new Mac or performed a clean install of OS X, you are presented with Setup Assistant, allowing you to create the first user account and specify some initial information, such as keyboard layout and locale.
Under certain circumstances, it can be advantageous to re-run the Setup Assistant. Using some command-line trickery, we can do just this without having to erase and reinstall OS X.
What Setup Assistant Does
Setup Assistant is designed to run on the first boot of a fresh install of OS X, which is why you'll only see it when booting up a a brand-new Mac or one that has been erased and had OS X reinstalled.
Besides options for keyboard layout, time zone and asking if you'd like to register, Setup Assistant also lets you create a new user account. As Setup Assistant assumes the account it is creating to be the first, it is always given administrator privileges.
Why Bother?
There may come a time when you need to set up a second user account on a Mac while attempting to resolve a user account issue. If a Mac has only one user account and it seems to be unable to log in correctly (getting stuck at the login window, for example), having a second account will allow you to access OS X and continue troubleshooting.
Sticks & stones mac os. By re-running Setup Assistant, we can use the process to create a user account that will automatically have administrator privileges, without having to do so via System Preferences, which we might not be able to access.
There are other reasons why re-running it can be advantageous, though in my experience, the above has always been the most common reason to do so. Sure, you can create user accounts using a number of commands, but Setup Assistant is just far easier.
.AppleSetupDone
Every time OS X boots, it checks for the existence of a file known as .AppleSetupDone. This empty file is created after the completion of Setup Assistant. It doesn't exist on a brand-new, out-of-the-box Mac, nor on one that has had a clean installation of OS X.
Installation For Social Media Breakup Coordinator(wip) Mac Os Pro
By removing this file, OS X will assume that Setup Assistant has never been run and will launch it as soon as OS X boots.
Setup Assistant is also run with root privileges, which is why it can create a new user account with administrator privileges without the need for any authorisation.
Removing .AppleSetupDone
To remove this file, we need to boot the Mac into Single-User Mode. This provides a method of interacting with OS X via the command-line, with full root privileges.
Start up the Mac whilst holding down ⌘-S. After a few moments, you'll see the Mac boot to the command line.

Before continuing, the filesystem must be checked and mounted, so files are't immediately accessible to interact with. To do this, enter the two commands that are displayed within the prompt, one at a time.
The following command will check the filesystem to ensure there are no problems. Enter:
The next command will then mount the filesystem for it to be accessible:

With the filesystem mounted and accessible, it's time to remove the file so OS X will re-run Setup Assistant:
After that, simply enter reboot and your Mac will restart and boot normally. Only this time, Setup Assistant will launch.
Security Concerns
By now, you're probably wondering why should this be even possible, since someone may use this to gain access to a Mac. Indeed, re-running Setup Assistant would certainly allow for an unauthorised person to create a new account with administrative privileges and gain access to the Mac along with your data.
In terms of security, physical access trumps almost every method of preventing unauthorised access not involving encryption. While a little more complicated with the SSD technology Apple uses in their product lines, access to your data can easily be done simply by removing the Mac's storage device and connecting it to another.
This is where encryption methods such as Firmware Password and FileVault 2 are useful. With a Firmware Password set, it must be entered if the Mac is being booted either into Single-User Mode or to another boot volume. FileVault 2 takes this one step further by performing full disk encryption, preventing any form of access to your data unless authorised by entering your user account password - even if the drive is removed and attached to another Mac.
