Hi, today my Mavericks crashed while apparently sleeping. At least I put it to sleep before coming home, finding it an unresponsive state; displays were blank and I couldn't SSH in. So I hard-resetted. Since then my trackpad isn't working properly anymore: the only thing I can do is move the cursor and click; no gestures, tap to click or secondary clicks! Keyboard is working for the most part but also has some sporadic hiccups: pressing keys (mostly Opt-<letter> combinations) trigger volume ups/downs suddenly my displays get mirrored. Somethings obviously wrong but I cant't figure it out. Already changed batteries, severals restarts and file system checks. No luck! Any ideas? Thanks in advance!
