Couldn't agree more. I can't open my coworkers KeyNote presentations because my copy is a year newer. My two year old Macbook Retina Pro black screens half the time it tries to wake up from sleep and yes, I've wiped every startup program and kernel extension. I'm just glad it isn't my work Macbook Pro which black screens on login half the time and insists I forgot my password and won't let me time my password in another quarter. I suspect it has something to do with disk encryption since it started after they turned File Vault or whatever it is on.
