Do you have a 2013 MacBook Air? And, if so, have you experienced any unexpected crashes or freezes?
You are not alone.
Reports of crashing, freezing and black screens have been common for some months, with users needing to use a hard restart to clear the problem.
This comment, from Math_Geek, is typical of the complaints.
Now, MacRumors reports that an unnamed Apple Authorised Service Provider has claimed that Apple is aware of the issue and is about to address it in an update that will prevent the 11in and 13in machines from failing to wake normally.
The service provider claims that the problem is due to “a bug in the sensor that detects when the lid is being opened, which has led to multiple machine returns and replacements as it was previously unclear whether it was a hardware issue or a software issue”.
Now it appears the issue is Mavericks related. And an Apple Support Representative has confirmed the service provider’s claim that Apple is working on a fix and it should be bundled with the next Mavericks update, which would be 10.9.2.
“The problem is related to OS X Mavericks and requires a combination of the computer going to sleep and a press on the keyboard or touchpad to initiate,” reports MacRumors. “One user has been able to successfully recreate the problem by pressing the power button to put the MacBook Air to sleep and then immediately clicking on the touchpad, which causes the machine to freeze.”
Until the update appears, users are advised to continue using a restart to deal with the issue.
