I have Macbook Pro retina, model 2013. It started to randomly shut down for no apparent reason. The system log always contains this message:
Previous shutdown cause: -104
I have tried to reset SMC and PRAM several times. It did not help. The hardware test found no errors. I have tried to google the meaning of shutdown code "-104", but I could not find anything.
Can anyone please provide any info about what's going on and possibly how to fix it? Thanks.
