I recently installed a new SSD into my iMac along side a new HD. I wiped the computer and installed a fresh OS with fresh files on my SSD. On the HD, I copied all the files from my time machine backup directly onto the HD and many of the files are locked / unusable. How do I unlock all the files on this drive? I changed the sharing & permissions of my music folder and it visually appears to be unlocked, but when I try to add my old library to iTunes on the SSD, it says: "The iTunes Library.itl file is locked, on a locked disk or you do not have write permission on this file." Does anyone know can I completely unlock all these files? Thanks in advance for any help.
