Prevent Mac from stealing USB mount?

Postby fearless_fool » 21. May 2019, 17:37

I have an embedded development board that presents a USB mountable filesystem when plugged in, and MacOS (Mojave v10.14) duly mounts it.

The problem is that if I ask MacOS to unmount the filesystem, it automatically re-mounts a few moments later, and thus prevents my Windows image running under VirtualBox from gaining access to the USB.

Is there an easy fix for this?

Add a USB filter for the board.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.

If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.
