Cannot give myself access to hard drive
I bought a new iMac and merged my old Macbook Pro info over from a Time Machine backup. Everything went well for moving the apps, favorites, and settings over but it did not move my folders over. I moved them to my desktop today and when I tried to drop them into the internal hard drive it won't allow me to do it. When I pull up the get info window on the HD my name isn't there so I click the plus button and when I try to add my name it tells me I don't have the permissions to add me even though I am in users as an admin. I ran disk first aid and even did it from safe mode. Any idea how to fix the issue?
