iMac Pro

Apple released macOS High Sierra 10.13.4 to the public on Thursday. In addition to going hand in hand with iOS 11.3, which was released earlier in the day, the update features Business Chat, support for external GPUs (eGPUs), Messages on iCloud, and more. Users will also find the gorgeous wallpaper included with iMac Pro, shown below.

Business Chat

Andrew Orr wrote up a great piece about Business Chat. Cribbing from that, Business Chat will work across Apple’s devices like iPhone, iPad and Apple Watch, but not the Mac. Apple customers can start a conversation with a business from Safari, Maps, Spotlight, and Siri.


External GPUs are video cards running on an external PCI breakout box, particularly through Thunderbolt 3, such as OWC’s Mercury Helios FX. It allows Mac users to harness newer, or simply even more, GPUs than the internal one that came with their Macs. This can be especially important for video pros using MacBook Pros.

Messages on iCloud

This feature shifts local storage of iMessages to iCloud. Rather than storying everything locally and syncing everything up when you use your individual Apple devices, those devices will instead pull just recent messages from iCloud.

If you have lots of iMessages chats and group chats going—and if those chats are image, movie, or other files-heavy, this will save you gobs of space. For instance, my Messages folder is currently 11GB and growing. It will also make syncing on devices you don’t use every day a lot faster.

  • Actually, Messages on iCloud is not mentioned in the release notes. A quick trip to Messages preferences and I see the feature is not there. It’s also been reported that it’s gone in iOS 11.3 so you might want to remove it from your article.
