I am trying to install USB 3.0 compatibility drivers on my MacBook Pro 17 2011, just purchased a USB 3.0 PCI Express card and was recommended to me I use this program to install the drivers. I am running OS X Sierra on a 2.5 GHz Intel Core i7 with an AMD Radeon HD 6770M 1.2GB I select "Third Party USB 3.0" and got to build; it throws me the installation failed error with this log: 12/14/16 00:32:21 - Starting MultiBeast 9.0.1-20161010 12/14/16 00:32:37 - Mounting EFI 12/14/16 00:32:37 - Mounting EFI failed. Exiting. I have already tried restarting, reinstalling, and I am running as an administrator; no luck. Much help is appreciated...
