How to debug an OS X crash? I have a 15-inch, mid 2010, MacBook Pro with OS X 10.9. It crashes very often (about 0-3 times a day). I have installed all available updates. Where do I start searching for the root cause of the problem? It could be some 3rd party product. Should I start uninstalling the 3rd party programs till the problem disappears? My suspicion is that it has something to do with the video driver, as the crashes happen when I maximize a photo in Facebook, for example, or do some other things related to changing something in the display. However, I updated the video driver and the problem persists. I also have the stack trace from the crash, but I can't read it. If anyone can point me to a tutorial about reading such a trace, it would be nice. Any advices about the problem are welcome. Thank you.

P.S. The problem was caused by a faulty motherboard.
Start with log files.  You have a program in your Applications &gt; Utilities folder called Console; Fire that up, and it will show you a collection of log files - you should inspect these to see if there is anything obvious showing up at the time of your crashes.  Once you have discovered something that looks odd, or consistent across your crashes, you can google it or ask again here.
