I started by just recalling the WiFi Chip which did actually bring back wifi. But it got very hot and threw a temp warning every minute or so. So I removed the...

    A1502 820-3536A working, but turns off after about 30 minutes

    No seems to work fine. The only thing I found weird (could also be an OS Bug though) is that it goes to sleep while playing YouTube.... Yes original charger, though this reboot was on a genuine battery

    Yup, maybe should get one soon. Also now found out what is the reason for the crashes according to macOS as I finally got a log... Is that of any use? Will try the new EFI file you sent today. Will report back on what happens. BTW as Long as the Machine is on all the Time and never goes to...

    A1502 2013 13? MacBook Pro Fan Spin, no chine or Display output

    Back to this old thread after over a month. Got a replacement U1950 in, made no difference. Also tested the original one on a known booting board and it worked. Any other ideas on what I can try?

    820-3462A A1425 2012 13" Retina No s5 rails

    Hi, have this 820-3462A A1425 2012 13" Retina Board that used to have a shorted SMC. Well I finally tracked one down an replaced it. Board still won't work though. It does have the orange light (so 3V42 definitely working) and PPBUS_G3H is normal. Any suggesting? Which rails should I post?

    A1534 Classic SSD failure

    Hi, have a question. Is there anything theoretically possible to fix a1534 MacBook 12" Units with failed SSDs. I mean you can fix failed iPhone NANDs by replacing them and reprogramming the new one. Something similar possible here?
