Trying to get Ubuntu Precise 12.04 to communicate with Apple's iMac 10.8.5.

Copying files / folder from share Mac to desktop Ubuntu 12.04 gives files all 0 bytes, folders error on directy cannot be copied and movies also copy to 0 bytes on ubuntu precise.
Shares can be accessed flawlessly on Mac but nothing can be copied nor used.... so to speak.
