They have the public betas (available to anyone) but this is a developer beta and requires a developer account (albeit you don't need to pay the $99 anymore). They should probably put it behind the $99 barrier again. It astounds me that people on a site like HN can install a developer beta and then act shocked that it's not 'buttery smooth'. Companies either need to educate people or make it difficult to access beta software again.
Doesn’t look like you require anything. I don’t have a developer account and I can select the developer betas on my MacBook and iPad.
