Apple CEO Tim Cook reveals that an extraordinary number of people are taking part in the company's beta program which includes early versions of iOS, macOS and other major operating systems of the company.
In a teleconference to investors following Apple's release of third-quarter results Thursday, Cook said that around four million people are using beta software on their iPhone, iPad, Mac, Apple Watch, and iPad Apple TV devices operate.
"In June, we hosted a hugely successful developer conference that demonstrated many important advances this fall on our four operating systems, iOS, macOS, watchOS, and tvOS," said Cook. "The response from developers and customers has been very positive and we have over four million users of our new operating system beta programs."
The number of beta program subscribers is not typical for Apple, so it's unclear how that number will be compared in recent years. Also unknown is how the participation statistics are broken down by operating system and whether developers are included in the number.
Apple frequently praises both the growth of the app store and its contributions to the app developer profession as a whole, so it's a good guess that the four million for software beta subscribers in a year's time are the biggest ever belong to Apple, if not for the history of the computer altogether.
At WWDC, Apple unveiled iOS 12, Mac OS 10.14, watchOS 5, and TV OS 12, and since then has periodically released beta editions of each in the past few weeks. Full releases are scheduled for this fall.
