Build number 23D56

Also the Ventura 13.6.4 RC 4 is build 22G513 and Monterey 12.7.3 RC 4 is build 23H1015

Other new builds:

audioOS 17.3 RC build 21K646

tvOS 17.3 RC build 21K646

watchOS 10.3 RC build 21S644

iOS and iPadOS 17.3 RC build 21D50

iOS and iPadOS 16.7.5 RC build 20H307

iOS and iPadOS 15.8.1 RC build 19H380

3rd gen AirPods build 6A321 - this one is not an RC - it is a public release

ipsws available for all of these except watchOS, audioOS, Ventura and Monterey, airpods

Full installers not available. Although older Ventura and Monterey RCs are available they probably won't be this time.

The full installers for Sonoma, Ventura and Monterey will however be available upon public release, potentially but not necessarily with the same build numbers as the new RCs.

I had it hanging like that too for quite a long time. I force restarted it, redownloaded and the second time it installed without stalling.

Hopefully this fixes the external USB drives disconnecting constantly

Current workaround is to use amphetamine.app to force wake them every 5 seconds

The bug where the mouse cursor is not changing form based on what it's hovering over, is still not fixed.
This has been a thing in MacOS (and OS X) for decades...
Happens in Windows too, but less frequently for sure. But I think what you mean, in Electron based apps it has since Sonoma been more common to see the text selection pointer instead of the arrow pointer when doing a right-click in a text to bring up the contextual menu.
