The latest builds can be downloaded by developers taking part in the beta-testing program via the Apple Developer Center, or as an over-the-air update for any hardware that’s already running the beta builds. Public beta versions of the releases generally arrive a short while after their developer counterparts, available through the Apple Beta Software Program website.
Both AppleInsider and Apple itself strongly advise users don’t install beta operating systems, or beta software in general, on to “mission-critical” or primary devices, as there is the chance of issues that could result in the loss of data. Testers should instead use secondary or non-essential hardware, and to make sure they have sufficient backups of their important data at all times.
