To all OpenAFS and AuriStorFS macOS users,

Next week Apple is expected to release macOS High Sierra to the public
as a free upgrade.

Apple has published the following document describing the upcoming
changes that institutional end users must prepare for.

  Prepare your institution for iOS 11, macOS High Sierra, or macOS
  Server 5.4

    https://support.apple.com/en-us/HT207828

In that document Apple references two sets of changes that impact
macOS systems upgraded to High Sierra if an OpenAFS or AuriStorFS client
is installed.

 1. Apple File System (APFS)

    As part of the High Sierra upgrade the local file system will
    be converted from HFS+ to APFS.  Unfortunately, the OpenAFS
    and AuriStorFS disk cache is file system dependent.  All OpenAFS
    clients for macOS and all AuriStorFS clients for macOS prior
    to AuriStorFS v0.160 are unaware of APFS and will panic the machine
    if the disk cache is located on an APFS volume.

    Today, AuriStorFS v0.160 has been published to the AuriStorFS
    download web page:

      https://www.auristor.com/filesystem/client-installer/

    Prior to performing the macOS High Sierra upgrade, any installed
    OpenAFS or AuriStorFS must be uninstalled or upgraded to
    AuriStorFS v0.160.

    As with any macOS upgrade, after the upgrade the High Sierra
    specific installer for AuriStorFS should be installed.  The
    macOS High Sierra v0.160 dmg was published to the AuriStorFS
    download site today.

 2. User Approved Kernel Extension Loading

    https://support.apple.com/en-us/HT208019

    Apple has decided that newly installed kernel extensions will
    require "User Approval" before they can load.  "User Approval"
    is more than just running an installer with Administrator
    privileges.  After installing AuriStorFS on macos High Sierra,
    an end user will have to manually approve the kernel extension
    before /afs can be accessed.

I realize the time is short.  Apple is expected to release macOS High
Sierra on Tuesday 26 September 2017.  AuriStor, Inc. became aware of the
panic after upgrade issue a couple of days ago.
