Apple Releases macOS High Sierra 10.13.5 With Messages in iCloud Support

Friday June 1, 2018 10:04 am PDT by Juli Clover

Apple today released macOS High Sierra 10.13.5, the fifth major update to the macOS High Sierra operating system available on Apple's Mac lineup. macOS High Sierra 10.13.5 comes more than two months after the release of macOS High Sierra 10.13.4, which introduced eGPU support, Business Chat in Messages, and more.

macOS High Sierra 10.13.5 can be downloaded directly from the Mac App Store or through the Software Update function in the Mac App Store on all compatible Macs that are already running macOS High Sierra.

The macOS High Sierra 10.13.5 update introduces support for Messages in iCloud, a feature that Apple has been testing and working on since macOS High Sierra was announced last June.

Messages in iCloud, as the name suggests, stores your iMessages in iCloud rather than on each of your individual devices, introducing improved cross-device syncing and saving on-device storage space. Messages in iCloud support is also available in iOS 11.4, which was released to the public earlier this week.

macOS High Sierra will be followed by macOS 10.14, a next-generation version of macOS that Apple is expected to introduce at the Worldwide Developers Conference next week.

Apple today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name. The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...

Messages in iCloud: delivered on the last business day before it'd be a year since it was announced at the last WWDC. Haha.

There was a time when Apple refrained from vapourware. Today, under Cook, they are beginning a dangerous trend into vapourware that brings the respect level down several "notches".

It is one full year and now they are delivering it. These guys used to perfect things in the back before releasing, and one could buy products and use services right on the day of announcement, not any longer. I do not know why, understand why, but I do not like this trend.

Messages in Cloud: 3 days before iOS 12 instead of shipping with 11.
HomePod was announced to come months later, released even more months later.
iMac Pro, previewed. Why! Just launch when ready!

There used to be pride in it. But I do sincerely feel that any kind of personalisation, any sort of character of a company was lost the day Jobs passed away.
