The current release of Imagr supports running in macOS 10.13 High Sierra and restoring APFS volumes. However, the following should be noted when testing.
Important! When you restore an APFS disk image it will wipe the entire device, not just the partition you specify. For most users, this won't be an issue, but you should be aware of this if you use Imagr with multiple partitions.
What needs testing?
The following still needs extensive testing on macOS High Sierra (10.13):
- Restoring both HFS and APFS images
- Running scripts at both during the Imagr run and during first boot
- Installing packages at both during the Imagr run and during first boot
- Partitioning and formatting disks
Jul 26, 2017 First of all you'll need to have Install macOS 10.13 Beta.app in your Applications folder. Then, you'll need to right click it and then go to Show Package Contents/Contents/Shared Support and from there mount InstallESD.dmg. Once mounted there you'll find Packages folder and inside Core.pkg. Double click Core.pkg and this will install macOS to desired partition, SSD or HDD. As I've referred Sierra installs fine, no problem whatsoever (have had to do it 4 times this past month, because High Sierra broke every upgrade attempt) Never had a single hardware problem with this Macbook Pro late 2011, and have been able to setup every single OS X or macOS without any problem until now. Aug 02, 2017 If you want the ability to perform a fresh and clean install of macOS High Sierra, then you should consider creating a bootable macOS High Sierra USB install drive. Not only will this walkthrough.
Your nbi
Currently, only AutoNBI images support booting into 10.13. This is the tool that is used during make nbi.
Firmware
To be able to boot from a APFS formatted disk on a Mac that has never had APFS before, the target Mac's firmware needs to be updated. An update package can be generated using the following script (thanks to Greg Neagle & Pepijn Bruienne for their work on this).
Installesd Dmg Pkg High Sierra Pro
The script requires a copy of High Sierra in your /Applications folder. A full .app is required (not a stub installer)
The resulting package (located at /tmp/FirmwareUpdateStandalone/FirmwareUpdateStandalone.pkg) should be used in a package component that is installed during the Imagr run (so first_boot should be <false/>).
Installesd Dmg Pkg High Sierra Springs
Disk format
You should format any existing HFS disks as APFS using Disk Utility before restoring an APFS disk image into it.
