I've owned a Macbook Pro 2008 (used from 2008 - end 2012) that ran Snow Leopard and Windows XP, a Macbook Air 2010 (used from nov 2011 - nov 2013) that ran Snow Leopard, a desktop (used from 2013 - present) that runs Windows 7, and finally a Macbook Air 2013 (nov 2013 - present) that runs Mavericks. I recall a handful of crashes and BSODs on the MBP2008, but such crashes were rare and only occurred once a month at most. For the MBA 2010 and Win7 Desktop, I can't recall any incident where they have crashed. My 2013 MBA on the other hand has problems at least once a day. Sometimes when waking it up from sleep it has problems with the audio or trackpad. No audio is played with or without headphones, and only a reboot fixes it. Trackpad fails to register single taps or clicks but right clicks are fine. It also crashes fairly often. Sometimes the monitor simply goes blank halfway. From the back I can see the LCD is still on, but it's completely dark on the monitor and nothing responds. On other times, it simply freezes. On both occasions I have to hold down the power button to force it to turn off, then reboot it again. It's frustrating as hell and the only thing that makes all this crashing bearable is that it reboots so quickly. Anyone else facing similar issues? Daily crashes isn't even something I expect to see on a Windows XP computer, let alone a from a 2013 Mac.
