Hello - I have Macbook Air running macOS Sierra version 10.12.1
I have an external USB drive that contains encrypted files. When I run the file "RemovableMediaAccessUtilityC.dmg" it produces the the error message "You must start Removable Media Access Utility from a removable storage device to view the contents of the device. Contact you administrator". I confirm I am running the file from a USB device, which the Mac mounts during installation.
If I run the .exe file from a Windows machine, eveything loads fine. The problem is the .dmg file won't run on the mac.
I no longer have access to the original computer where the files were copied from
Please help!
