Chosen Solution
I have a late 2013 MacBook Pro running Mojave with 16GB memory. Has battery on 2 years old. Replaced the SSD with OWC Aura Pro X2 SSD / 2 TB. Goes well. But, when I put the computer to sleep, it will shutdown after about an hour even if the battery is at full charge. I can stop this by plugging in the charger. I also have a 13” MacBook Pro 2015 in which I put a OWC 1TB SSD and it is doing the same thing. Have zapped the PRAM several times without success. Anyone having similar problems? Thanks
OWC has some SSD firmware updates, did you check it? OWC firmware updaters
