Rispondi a "How do I replace the stand hinge mechanism?"A simple fix-it is to place a rubber cane or crutch tip ( available from almost any pharmacy) between the stand and the body of the computer. It's even adjustable. And then proceed to give Apple !&&* for not making this endemic problem a recall. I had a 27 inch iMac , model 2007 for 8 years with never a hinge problem. With it's replacement a 2013 model the hinge broke after two years.
