macOS 10.13 High Sierra is the fourteenth version of macOS, and the follow up to macOS Sierra. Much like how OS X Snow Leopard was a refinement of OS X Leopard, macOS High Sierra is highly focused on refining macOS Sierra.

Yet the release does add some brand new features to the table. Noteworthy additions include external GPU support, which provides compatibility with VR headsets for the very first time, and Apple File System (APFS), which replaces the previous HFS+ file system.

Update #2: An official fix is now available; no restart required.

Update: An Apple spokesperson has issued the following statement, saying an update is in the works:

“We are working on a software update to address this issue. In the meantime, setting a root password prevents unauthorized access to your Mac. To enable the Root User and set a password, please follow the instructions here. If a Root User is already enabled, to ensure a blank password is not set, please follow the instructions from the ‘Change the root password’ section.”

A newly discovered macOS High Sierra flaw is potentially leaving your personal data at risk. Developer Lemi Orhan Ergin publicly contacted Apple Support to ask about the vulnerability he discovered. In the vulnerability he found, someone with physical access to a macOS machine can access and change personal files on the system without needing any admin credentials.

Users who haven’t disabled guest user account access or changed their root passwords (likely most) are currently open to this vulnerability. We’ve included instructions on how to protect yourself in the meantime until an official fix from Apple is released.

When Apple announced that it would lend official support to eGPU setups via Thunderbolt 3, I was extremely happy with the news. It means adding more graphical power on demand to Thunderbolt 3-enabled Macs like the MacBook Pro.

Just for the fun of it I decided to test the Sapphire Radeon RX Vega 64 inside of a Mantiz Venus external graphics box connected to a 2017 13-inch MacBook Pro. Although official driver support isn’t yet there, I can report that when running the latest macOS High Sierra 10.13.2, the RX Vega 64 does work to some degree. Here’s a hands-on video look at what I found.
