Haven't seen this info published yet, so here goes.

This is how you can join the public beta or developer seed program.

 

This is basically what the macOSSierraPublicBetaAccessUtility does.

Please note that there are currently three types of seeds available.

* PublicSeed

* DeveloperSeed

* CustomerSeed
