Apple has released macOS 10.13.4 High Sierra, a 2.36 GB update you can install via Software Update or as a standalone 2.49 GB combo updater. It’s a minor update but does offer some nice tweaks and additions. As always, we recommend waiting a few days before installing to make sure that the update doesn’t cause any unanticipated problems.
The key new feature is support for Apple’s new Business Chat service, which lets you use the Messages app in macOS (and iOS 11.3) to communicate with participating businesses. If a firm is signed up for Business Chat, you’ll see that information in its listing in Maps, Safari, and Spotlight search. Initial launch partners are 1-800-Flowers, Ameritrade, Apple (obviously), Discover, Hilton, Home Depot, Lowe’s, Marriott, Newegg, and Wells Fargo.
High-End Graphical Improvements
There’s some big news for Mac professionals with high graphical requirements: macOS 10.13.4 now supports external graphics processors, which can be connected to a 2016 or later MacBook Pro, 2017 or later iMac, or an iMac Pro to boost graphical performance for media creation, 3D gaming, virtual reality, and other demanding applications. The update also addresses graphics corruption issues with certain apps running on the iMac Pro.
Safari gets a bunch of attention in macOS 10.13.4:
- You can now jump to the rightmost open tab by pressing Command-9.
- You can sort Safari bookmarks by name or URL by Control-clicking bookmarks and choosing Sort By.
- To protect privacy, Safari will autofill usernames and passwords only after you select them in a Web form field.
- Safari will display a warning when interacting with password or credit card forms on unencrypted Web pages.
Like iOS 11.3 (see“iOS 11.3 Adds Battery Health Screen and Much More,” 30 March 2018), macOS 10.13.4 displays privacy icons and links to explain how your data will be used and protected when Apple features ask to use your personal information.
macOS 10.13.4 fixes a bug that prevented Web link previews from appearing in Messages.
Enterprise Content and Security Updates
For enterprise users, macOS 10.13.4:
- 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
--eraseinstallflag to the
startosinstallcommand in the macOS Installer app at Contents/Resources/startosinstall. Use this flag to erase and install macOS on a disk. For details, run

Finally, macOS 10.13.4 includes 34 security updates.
