Apple on Tuesday seeded the first beta of macOS High Sierra 10.13.5 to developers, just under one week after releasing the macOS High Sierra 10.13.4 update. It’s not clear as of yet what type of changes 10.13.5 will bring, but we’re expecting bug fixes and other improvements not addressed in the previous update.
We are waiting on several features to come to macOS and iOS, including Messages on iCloud, a feature that was in the iOS 11.3 beta but later pulled. Messages on iCloud has been reintroduced in the iOS 11.4 beta and is likely in macOS High Sierra 10.13.5 as well.
The previous macOS High Sierra 10.13.4 update brought support for external graphics processors (eGPUs) along with Business Chat in Messages and several other bug fixes and smaller feature improvements.
Registered developers can install the new beta via the Update tab in the Mac App Store, and it should be available in the Developer Center shortly.
