I am using a MacBook Pro Retina 15-inch (Mid, 2015) running macOS Catalina 10.15 Beta (19A558d).
I want to use an external USB-C SSD drive (512GB) to use Windows To Go and store other files. Since my MacBook Pro only has type-a USB ports I also bought a USB type-c to type-a adapter.
However, my MacBook Pro does not recognize the USB-C drive, not in Disk Utility, not in BootCamp Windows, not in System Report, or anywhere else I've checked. What's more, the light on USB device is not blinking, which might infer that the device has no power.
So far I have:
- ensured the MBP is full charged and also tested while connected to AC power
- tested the SSD USB devices on my phone (which has a USB type-c port), and it powered up and was recognised fine
- tested the adapter by connecting it to my Surface Pro 6, and everything works fine
- tested the adapter on my MBP but with a USB-C flat drive instead and everything works fine
Consequently, I think the MBP is not giving enough power to power up the USB-C external drive.
Can anyone offer a suggestion on how I may get the USB-C external drive to work with my MBP?
P.S. I found a similar question here.
