Hi all, I have recently installed OSX Mavericks on both my macbook pros, The first one is the latest version and the other one is macbook pro 13 inch 2011 model. I have a Western digital my book live duo 4 TB. My older mac now is unable to connect to my WD duo. When I click on its name in finder and the finder restarts. My newer macbook has no problem connecting to the drive. Also neither of these macs had problem connecting to WD when they were running OSX Mountain lion. I fixed permissions and restarted but it did not fix my issue. Thank you for your help.
