Hello,

Since the installation of OS Catalina, I am no longer able to backup my Laptops to the external Harddrive of my iMAC. I get the ERROR 13 before the Catalina update it was possible. Now I am only able to Backup inside a folder inside my IMAC users/shared folder but the Harddrive on my IMac is not big enough to "collect" the Backups of my 2 Laptops, so that is not a solution. So I suppose it is a permission issue but I tried different things but I am not able to find the problem..
