Apple’s High Sierra is coming. Below are some links to help prepare for it—

Upgrade to macOS High Sierra

• Model specific firmware updates are required (via the internet) for each system. Monolithic system imaging is therefore only supported to re-install macOS High Sierra. Please see this article for upgrade methods and supported APFS creation tools:

Secure Kernel Extension Loading (SKEL)

• Administrator or standard user approval is required before loading new third-party kernel extensions. A future version of macOS High Sierra will be able to use MDM to enable or disable SKEL:

Apple File System (APFS)

• Upgrading to macOS High Sierra converts flash storage-based systems from HFS+ to APFS automatically. Systems with hard disk drives (HDD) and Fusion drives won’t be converted to APFS, but will support macOS High Sierra on HFS+ file systems. Apple File Protocol (AFP) is no longer supported from APFS volumes. SMB or NFS are supported file sharing solutions:
