In revealing hard numbers to USA Today on Thursday, Cue offered the first real indication of how well Apple's streaming music service is faring after its launch at the end of June.
"We're thrilled with the numbers so far," Cue said.
Apple on Thursday released a second beta build of its upcoming OS X 10.10.5 Yosemite update to developers for testing, including what appears to be only minor tweaks and bug fixes.
The latest beta, build 14F19a, comes a little over two weeks after the first beta version was pushed out to developers and users signed up for Apple's public beta program.
Like the first beta, today's build brings minor tweaks and bug fixes aimed at improving system stability, app compatibility and security.
A day shy of its one-month anniversary, Apple Music has reeled in more than 10 million subscribers on iPhone, iPad, iPod touch and iTunes, a report said Monday.
Anonymous sources connected to major music labels provided the supposed adoption numbers to HITS Daily Double, saying the swift and substantial uptake is surprising even for Apple. The data reportedly comes directly from Cupertino, which is sharing streaming statistics internally with content owners.
Today's El Capitan beta version, build 15A235d, comes less than one week after Apple seeded its last round of prerelease software for developer assessment, a round that included iOS 9 and watchOS 2 builds.
Today's beta 5 build carries over the same areas of focus from Apple's previous beta version as well as known issues with Photos, Apple ID and Language localization and formatting. Many problems can be traced back to iCloud syncing, likely due to incomplete or incompatible backend assets also in testing.
While most people tune in to Apple's WWDC keynote to figure out what's coming in the next version of the company's operating systems, the event is a developer's conference. Apple genuinely uses WWDC to introduce a lot of new technologies that end users will never experience directly. So with the exception of big news like Swift, the company generally does this in later, non-public talks and through the software released via its Developer Connection.
