wonderfully reliable MBP bit the pooch. I loved this model for its port options (FireWire AND Thunderbolt), its user expandability (16g RAM and TB SSD) and it’s overall vibe. I’ve tried reseating RAM and Battery, reinitializing SCM and other systems. Nada. I can’t find any new logic boards. Scared to go used or even refurb. Too broke to buy a new MBP. I have an appointment next week at Apple Store, but I’m becoming afraid I have few options. Any other things I should pursue? Any hope Apple store can save me? May have to go Wintel.
