Apple today released macOS High Sierra 10.13.5 to the public. This update features ‘Messages in iCloud’ which are updated automatically, so you always have the same view everywhere you use iMessage. When you delete a message, photo, or conversation on one device, it’s removed from all of your devices. And since all of your attachments are stored in iCloud, you can save space on your device.
This update also features bug fixes and performance improvements. Apple this week also released the first beta of macOS High Sierra 10.13.6 which just features more bug fixes and updates, and currently have not found anything new.
