I plugged an ESP8266 into my Mac (Sierra) yesterday and my computer crashed. Since then, I have not been able to get past the login progress bar for any user on the computer.
Best I can explain is probably a CH340 driver that I used in the past that I didn’t remove when upgrading the OS.
I removed usbserial.kext from Library/Extensions, renamed my Library/Extensions to something else, rebuilt my kext cache, ran csrutil disable, reset the RAM, tried logging in with shift, all the things they tell you to do - still no luck.
Anyone know what I can do (besides wiping the drive, of course)?
Thank you!
