I have similar problem with my MacBook Pro 2015 it doesn’t detect my new Transcend JetDrive 850, and even in a OWC Envoy Pro case still not detected. Not even Disk Utility detects it. Any help would be great! Thanks
First the OWC case is designed to support the Apple custom Samsung SSD so I don’t know if the Transcend SSD will work in it. What was your system running for MacOS before you took out the original drive?What happens when you put back the original SSD back in?Did you contact Transcend to see what they say? Update (02/09/2019) You’ll need to get a real Apple SSD for the Envoy case. Or get the case Transcend offers for their SSD.
