Apple just put a lot of work to all the developers launching the third beta of iOS 11.2, macOS 10.13.2, watchOS 4.2 and tvOS 11.2. If you have the previous betas, you can now do the update as if it were a stable version.
These betas arrive a week after the second beta of iOS 11.2, which opened for Apple Pay Cash tests to all Americans and introduced new wallpapers. By the way, now the funds arrived with the iPhone X will be present in all terminals.
Remember that we are talking about preliminary and experimental versions of these systems, which you should not install if you are looking for optimal performance of your devices. We are not responsible for the errors and the performance drop you may have with these betas.
