Chosen Solution
Hi! A couple of weeks ago, I powered on my Mac. A screen appeared with 3 icons: drive icon i.e. “Macintosh HD”, underneath “an upward looking Arrow”, and “WiFi signal” with the option “Choose Network”. When I clicked the drive icon, it asked for the password, which I fed but was not accepted despite repeated tries. Finally clicked the “Forgot Password” option and chose a new password. I did the hard-restart and this time tried to punched in new password - instead of showing password, it started splaying weird symbols - also, did not accept the password. Had a long call-session with Apple and was asked to punch various keys, including resetting of NVRAM, but nothing happened. I then myself reset SMC which worked. As for weird symbols, I fixed it through Accessibility option. Mac worked fine for couple of weeks but today when I powered up, the same screen appeared with same issue. I did NVRAM reset - nothing happened. Then did SMC reset and this time it did not work. MacBook Air IssueAny suggestion please!
The problem you face here is the ultra compact nature of the logic board as clearly it is having problems. There just isn’t any way to fix it as you just can’t to the discreet parts without effecting the neighboring parts. Your only action here is to replacing it MacBook 12" Retina (Early 2016) Logic Board and here’s the guide Retina MacBook 2016 Logic Board Replacement
