Hello,
I recently bought a USB 3.0 to 4K Adapter (USB32HD4K) and installed 2.4b1, but when I connect the device, it doesn't show up or anything.
I tried the command:
Quote:

sudo mkdir /Library/PrivilegedHelperTools
|
And received:
Quote:
|
mkdir: /Library/PrivilegedHelperTools: File exists
|
Then I tried:
Quote:
|
ls -al /Library | grep PrivilegedHelperTools
|
And received:
Quote:

drwxr-xr-t 11 root wheel 374 28 apr 14:39 PrivilegedHelperTools
|
I'm running OS X Yosemite version 10.10.2 on a 13-inch MacBook Pro Retina.
