I have been engaged on troubleshooting a macbook professional which was donated to our makerspace which was rebooting again and again when plugged in. We did the usual stuff like making an attempt in addition in protected, restoration, clearing the NVRAM. We tried recent set up from an exterior USB, all have the identical impact, that after you select or it begins the boot course of previous the apple brand, (i.e. holding possibility and deciding on a boot gadget, or utilizing restoration and making an attempt in addition to the restoration system), it stops, no error, after which reboots.
I used to be in a position to get the machine in addition utterly into an OS from an exterior Ubuntu drive after which had the thought, what if I set up Ubuntu on the machine after which overwrite that set up with Catalina, to see if that may sidestep some wonky firmware gremlins (granted I am out of my depth right here, which is why I am asking for assist). Ubuntu put in tremendous and boots up with out problem from the interior drive, however after I tried to put in Catalina, it began doing the reboot factor (that means, deciding on possibility on energy up, then deciding on the Catalina USB set up stick, it begins booting from the stick after which reboots).
The reply I received from some Mac buddies is that it is the logic board and I would like to switch it, which is ok, however, if there’s a logic board problem, it appears odd to me that Ubuntu can run completely tremendous however any MacOS cannot. Anybody encountered one thing like this earlier than and any ideas?
