Macbook keyboard and trackpad not working in OSx
A client brought me a Macbook A1502 with a non-working keyboard and trackpad, but when I decided to test them in another OSs (Linux MX and HBCD in my case) and they work perfectly.
I tested them in High Sierra and Big Sur in safe mode but they didn't work.
Another thing that is happening is that the keyboard is not working on pre-boot, meaning that I can't reset the NVRAM, or even use ALT to boot into another OS, I've been using an extenral keyboard this whole time. The only key combination that is working is SHIFT+CONTROL+OPTION to reset the SMC, but I think that it's working becuse the Macbook is off, as soon as I turn it on, nothing works.
Yes, I've already reset the NVRAM with the external keyboard, and re-seated the keyboard flex and trackpad ribbon and still nothing.
