For the last few years, Apple have been releasing public betas of their major operating system updates in the Summer. Installing these public betas can be risky because they’re likely to contain bugs, and many apps won’t be updated to support major new OS updates until close to the official release date.
We would advise against installing major OS update betas on any device that you rely on to get work done and – even when they’re released to everyone – we always advise customers to be cautious about rushing to update. This year’s public betas seem to be causing problems with a wide range of apps, so we’d recommend staying away from them unless you absolutely have to install them for some reason!
We’re keeping a close eye on macOS Catalina and iOS 13, so expect to hear more about them from us in September.
