I have been running the Mavericks 10.9.1 beta for about a week, and overall it addresses a solid number of the usability issues that shipped with 10.9. So far so good, with one very specific and very annoying exception.
The system is kernel panicking and rebooting spontaneously, and I cannot pin it to anything except World of Warcraft. Ripping CDs, streaming music, general use — all fine. The moment I sit down to play, it is only a matter of time before the OS halts and restarts with no useful detail about what caused it. Every single time, it is during gameplay. Nothing else triggers it.
I am choosing to believe the operating system has developed opinions about how I spend my free time.
To verify the issue is actually tied to the 10.9.1 beta and not something deeper, I am rolling back to 10.9.0. If the problem disappears, that confirms it. If it does not, I may have to drag my dual Xeon tower in from the garage to keep the WoW habit alive and the Mac out of trouble.
More to follow once I have results.
