crashing
whenever my MBP goes to sleep, it crashes.
MacBook Pro (Retina, 15-inch, Early 2013), OS X Mavericks (10.9.2)
Without more info it's hard to know how to respond. For example, does it crash every time? Is it intermittent? How does it crash - frozen? non-responsive login? restart? Have you tried EtreCheck?
Some things to consider:
* Maybe this is caused by some third party software.
* Standard troubleshooting includes resetting NVRAM and PRAM, and Resetting the System Management Controller.
