need to change the name of the internal HD
Needed to replace the internal HD with an external SSD. Was required to call new boot drive Macintosh HD. Now Time Machine won't back up as I have two drives with the same name. Although I excluded the internal HD from the items to be backed up, Time Machine still refuses to start the backup. Do I need to keep the Macintosh HD name on external drive? If so, how do I change the name of the internal HD ?
