Exactly one week after the last build, Apple has released Build 12F23 of OS X Mountain Lion 10.8.5 to developers. The new build is only three builds newer than the last, and this could mean that Apple is winding down on the development cycle for 10.8.5. This could mean a public release in the next couple of weeks (based on past development history). Apple continues to say that 10.8.5 includes no known issues, and asks developers to focus on WiFi, Graphics, Wake from Sleep, PDF viewing and Accessibility, and Mobile Device Management during testing. Thanks, D!
