iOS 11.4 beta 2
Oh, you thought Apple were doing May Day? No way, and proof of that is that this very afternoon they have taken out new betas for all their operating systems. Specifically the beta 3 of iOS 11.4, macOS 10.13.5, tvOS 11.4 and watchOS 4.3.1 .
The build number for iOS 11.4 beta 3 is 15F4061d and 15F4061e, the tvOS 11.4 beta 3 is 15L5560b and the High Sierra 10.13.5 beta 3 is 17F59b. If you have a previous beta version installed on any device, you can upgrade to this new version as if it were any stable version.
In these betas we’ll find support for AirPlay 2 and message synchronisation , although that doesn’t mean we’ll have it permanently in the stable versions. Let’s remember that we also saw it in the iOS 11.3 betas so Apple finally removed it.
As always, we recommend that you do not install these betas if you do not know exactly what you are doing. They are experimental versions, designed for testing purposes and not for use on the devices you depend on on a day-to-day basis. The best thing if you want stability and performance is to wait for the final and stable versions of these versions to appear.
