Imaging is dead. Secure Boot and the T2 system controller have changed the toolset available to Mac administrators. The new post-imaging world of Mojave requires new workflows. We learn about the role that 'off-boarding' or the erase/install step has in the modern macOS deployment cycle. In this session, we will explore the startosinstall command in detail and learn about its uses and limitations. Finally, we will introduce a few workflows and tools (Erase&Install.app) that you can use to quickly offboard or reset your Macs.
