nrf52840 DK - J LINK OB MSD readonly LINUX VM

I have recntly purchased a Nordic Semiconductors nrf52840 development board.
I am having issues with the J Link OB MSD. When connected to LINUX Ubuntu 20.04 LTS which is running on a VM (Mac osx), the drive appears as readonly.
I have tried 3 different VM's. VMWare fusion, Parallels and Virtual Box.

If i connect the development board directly to a Mac Book, Win 10 PC or LINUX VM hosted on Win 10 with VMWare it works fine.
The problem only occurs when running LINUX hosted on MAC OSX VM.

Does anybody have any suggestions on how to fix this?

Thanks for you support.
