      I  have a new Mac Pro computer and have migrated my files from my older computer to the new computer. In trying to open a Lightroom catalog on an external hard drive  I keep on getting the message "lightroom cannot use the catalog named " " because it is  not writable and cannot be opened. I have fixed all the "permissions" and yet it will still not open. How do I fix this?
