macOS 10.13.4 High Sierra is out, adding external GPU support

Yesterday, Apple released its mid-stream feature updates for iOS, watchOS and tvOS. Now, macOS 10.13.4 High Sierra is available to everyone.

One of the key new features is external GPU support. This is big news for those that need the extra power, such as those that edit video professionally, develop for VR, or play games. After all, with the exception of the 15-inch MacBook Pro, all MacBooks come with integrated graphics, which uses the system memory for graphics memory.

Another new feature is Business Chat in Messages, bringing macOS to parity with yesterday's iOS 11.3 update. Here's a list of other, more minor features that Apple included in its changelog:

Fixes graphics corruption issues affecting certain apps on iMac Pro.

Allows jumping to the rightmost open tab using Command-9 in Safari.

Enables sorting of Safari bookmarks by name or URL by Control-clicking and choosing Sort By.

Fixes an issue that may prevent web link previews from appearing in Messages.

Helps protect privacy by only AutoFilling usernames and passwords after selecting them in a web form field in Safari.

Displays warnings in the Safari Smart Search field when interacting with password or credit card forms on unencrypted webpages.

Displays privacy icons and links to explain how your data will be used and protected when Apple features ask to use your personal information.

Enterprise content:

No longer disables User Approved Kernel Extension Loading on MDM-enrolled devices. For devices with DEP-initiated or User Approved MDM enrollment, administrators can use the Kernel Extension Policy payload.

Improves Spotlight search results for files stored on network mounts.

Properly evaluates ACLs on SMB share points.

Adds the --eraseinstall flag to the startosinstall command in the macOS Installer app at Contents/Resources/startosinstall. Use this flag to erase and install macOS on a disk. For details, run startosinstall with the --usage flag.

Updates System Image Utility to allow creating NetInstall images that erase and install macOS to a named target volume.

One other thing that Apple didn't add to this release from the betas is a warning when 32-bit application are launched, stating that a future version of macOS will only support 64-bit apps; that future version will likely be macOS 10.14, which will be announced at WWDC.

To install macOS 10.13.4 High Sierra, open the Mac App Store and go to the Updates tab to get started.
