Hi,
The following message came up when trying to connect an external drive to the usb port:
"System extension cannot be used
The system extension /System/Library/Extension/IOstorageFamily.kext was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update."
Earlier I installed Disk Warrior 4.2. After using it I restarted the system and when I wanted to use a usb-stick the message came on the screen and the device did not function.
There was problems with the FW800 port as well.
This thread did not help me that much.. http://forums.applenova.com/showthread.php?t=34056
Would be very glad and grateful if someone could help me with this!
