path/to/installinstallmacos.py -compress To use this option, please run the command shown below with root privileges: Using the –compress option will allow installinstallmacos.py to generate a compatible disk image.
Update – 2-27-2018: Greg reached out to let me know that the –compress option’s primary function is to produce a disk image which is compatible with Munki and Imagr.īoth tools expect to find the macOS Installer application at the root level of a read-only disk image. This option will create a compressed read-only disk image, with only the macOS Installer application stored on the disk image. If it’s desirable to save space, the script includes a –compress option. If desired, this folder may be discarded once the disk image has been created. Note: A content folder owned by root is also created, which was used by the script to store the various downloaded components. In this example, I’m selecting option 1 to download the standard macOS Installer application for macOS 10.13.3. Once an option has been selected, the script then runs through the rest of the actions described above and creates a disk image with the macOS Installer application stored in the Applications directory of the disk image.
