Apple on Wednesday released the second beta of macOS High Sierra 10.13.5 to public beta testers, two weeks after seeding the first beta and three weeks after releasing macOS High Sierra 10.13.4. Today’s public beta is identical to the second beta provided to developers earlier this week.
macOS High Sierra 10.13.5 once again introduces support for Messages on iCloud, a feature that was present in macOS High Sierra 10.13.4 betas but pulled ahead of the release of the updated software. The Messages on iCloud feature also allows your older iMessages to be stored in iCloud rather than on your iPhone, iPad or Mac, saving valuable storage space. Older attachments are also stored in iCloud.
Beta testers who have signed up for Apple’s beta testing program will be able to download the new macOS High Sierra beta through the Software Update mechanism in the Mac App Store. Those who want to be a part of Apple’s beta testing program can sign up to participate through the beta testing website, which gives users access to iOS, macOS, and tvOS betas.
