Hi all, Recently (possibly since 10.9.3 or 10.9.4) I've been having an issue with my rMBP where, if I turn it on with an external monitor attached (via mini displayport, for the record), it makes the Apple chime, starts loading, then the screen goes black and it starts over with the message about having to restart due to an error. Then it will loop a few times before giving up and shutting off entirely. My "solution" so far has been to boot with the monitor unplugged, then plug it back in after... except that doesn't always work either. About 50% of the time, only in the last week or so, doing that causes the external monitor to not have to work at all. I have to reset my computer a couple of times every time I turn it on lately, which is really becoming a pain. Any help would be appreciated. I've tried resetting the SMC to no avail, though I'm not positive I did it right. I held shift, control, and option and the power button then released them simultaneously, but the MagSafe light did not flicker or change states, which I was told indicates it worked. I'm not sure if that always happens, though.
