My drive will randomly disconnect while mounted on my Macbook Pro 15 inch 2015. I had the issue, although seldomly, in December of 2018 when I first bought it, and I was running Mac OS High Sierra. I am now running 10.14.16 and while still intermittent, the frequency can sometimes be so bad that I cannot use it. I assume that I need to return it via RMA. I have used multiple thunderbolt3 cables and different ports on my Macbook pro. The computer and cables used have been stable with other thunderbolt3 drives and devices. Any suggestions before I RMA?
