Running macOS High Sierra without the APFS file system.

With the release of Deep Freeze Mac 7.0 this process is no longer required to support a system running macOS High Sierra, or Mohave. Customers wishing to run Deep Freeze on a system running macOS with a APFS formatted volume should upgrade to Deep Freeze Mac 7.0.

As of macOS 10.13 Apple systems running Solid State disks are, by default, being converted to use an updated file system called APFS on the boot disk. Deep Freeze does not support installation on a APFS based system and cannot be used on systems that have been upgraded to macOS High Sierra and converted to APFS at this time.

While Faronics does intend to support AFPS in a future release of the Deep Freeze product we at this time cannot provide a timeframe for support. For customers who wish to upgrade to High Sierra, and run Deep Freeze this document will detail a process for performing the macOS upgrade and suppressing the conversion of the file system to APFS

It is important to note that while converting to APFS is the default during the High Sierra install process not all machines are converted during the upgrade. Systems running a magnetic disk, or systems configured as a Fusion Drive are not automatically converted and continue to use the existing HPFS+ based file system on the boot volumes.

The attached document will detail the process of installing High Sierra and suppressing the conversion of the system to APFS in order to continue to be able to use Deep Freeze on the client system without interruption.

If the client system has already updated to High Sierra and has converted to APFS the only way to revert this setting will require a reformat of the disk and a reinstall of the operating system.
