Apple Releases macOS High Sierra 10.13.3 With Fix for Messages Bug

Apple today released macOS High Sierra 10.13.3, the third major update to the macOS High Sierra operating system available for Apple's Macs. macOS High Sierra 10.13.3 comes over a month after the release of macOS High Sierra 10.13.2 and a little over a week after a macOS High Sierra 10.13.2 supplemental update which brought a fix for the Spectre vulnerability.

macOS High Sierra 10.13.2 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.

No major outward-facing changes were discovered in macOS High Sierra 10.13.3 during the beta testing period, but according to Apple's release notes, it brings security and feature improvements.

The update offers additional fixes for the Spectre and Meltdown vulnerabilities that were discovered and publicized in early January and initially fixed in macOS High Sierra 10.13.2.

We also know that the update fixes a bug that allowed the App Store menu in System Preferences to be unlocked with any password. Aside from those changes, Apple's release notes say that the update "addresses an issue that could cause Messages conversations to be temporarily listed out of order."

Are they even going to release iMessages in iCloud at this point?

Haha, the bar started out, raced to 3/4th done, then said 39 minutes left.
In the future, to update, open a Terminal, then:

sudo softwareupdate -i -a

And enter your password. When it's done, type "reboot". It's much faster than using the App Store app, and does the same thing.

Have you tried submitting this bug to Apple's feedback site? https://www.apple.com/feedback/

The more people that submit bugs like this, the sooner Apple will pour time into fixing them.
Maybe when Steve Jobs was alive and kicking summiting bugs used to work, not anymore, the cat is gone and the mice ara having a party. Sierra renders PDF documents sharp and clear, High Sierra are blurry. Load a pdf document and see it for your self.

As always they fix this and break something else... That is the motto.

Apple if you read this, please fix Preview to render PDF documents properly. I hope I'm not asking for something impossible...

Are this downloads only for macOS High Sierra?
No. You can use the Gatekeeper one for any system from Mountain Lion onwards and the XProtect one from Mavericks onwards. So many systems use them, not just High Sierra.

Is there any order to install? I mean after installing iTunes 12.7.3 and macOS High Sierra 10.13.3 Combo Update can I continue installing the new xprotect and gatekeeper? or I have to install first xprotect and gatekeeper?

Thanks
Came
Order won’t matter.
