Apple’s first iOS 10 beta ships with an unencrypted kernel that will make it easier to hunt down flaws in its code. This gives the company a greater chance of eliminating possible holes before the final version is made available to all this fall.
Some users of early 2009 iMacs who have upgraded to OS X Snow Leopard or higher are still reporting issues with a kernel issue that seems to be due to the Nvidia GeForce GT 130 graphics card that came with the machine, with nary a response from Apple proper. There’s a thread on Apple’s support discussion pages that is now around a year old that mentions the problem. According to the posters there, there was a faulty kernel extension released in one of the later Snow Leopard updates that can cause graphics glitches and even kernel panics when there’s a heavy load on the video card, like when playing games. Apple has not yet responded in the official forums.
Some early Macbook Air adopters have reported seeing video anomalies and kernel panics on the new 11-inch and 13-inch models of the Macbook Air which may be related to sleep/wake issues.
Additional reports about the video problem have been posted to Apple’s discussion forums and for the people reporting it the symptoms can vary. I’ve even encountered the problem myself on my 13-inch MacBook Air.
The problem with kernel panics has been experienced by Cult of Mac staff that purchased 11-inch or 13-inch models. Users on Apple forums haven’t complained about this specifically yet, but they have been complaining about their new MacBook Airs crashing.
