Due to a failure of my primary disk, I had a new disk installed and all data transferred from my external backup. When trying to open my file on the new disk, I was received a message that I did not have permission to write to this file. I am the admin, so I checked permissions and all looked ok. i went back to my external backup and found I could still open the file without any problem. I called support for help, but after an hour of downloading a new app and trying to backup to the new disk, I still received a permissions message, only this time it indicated I did not have permissions on the new disk. The tech gave up and suggested I do back to the repair shop that did the installation and file transfer. Also, I have a copy of the file on my new disk, but when I look for it it does not show in a search. I have the same problem with the backup disk, unless I search by clicking on the Q in the corner of the open file. When I do this, Library is greyed out. Anyone have any thoughts on this problem?
