Ever since I have installed the beta versions of Mojave, I am constantly having to authenticate file moves. When I "get info" on my boot drive, I am not listed as a user. I try to add my self (I am the only administrator/user on the account), but the system responds with " You don't have the access to complete the operation. Has anyone else had the same issue? Any suggested fix? I am not listed in the box when I do "get Info", When I try to add myself, I get the error message. I have found a workaround, by turning SIP off, adding myself, and then turn SIP back on, but I believe that this is a bug in the OS, can anyone confirm this?
