I am trying to migrate a user from an old mid 2010 iMac with OS X 10.9 (Mavericks) to a new iMac Pro with macOS 10.14 (Mojave).
Using the Migration Assistant with a time machine backup of the old machine seems to work -- all things seem to be back in place (Mail has the old accounts, all files are there, etc.).
Unfortunately, there is one issue with the home folder: I cannot open it in Finder -- it is 'transparent/grayed out' and it is not possible to open it via double-click. However, I can directly browse to its contents via the "Go To Folder"-command (SHIFT + CMD + G). Also in the terminal, for some operations on the folder i get the error message "Operation not permitted".
I did verify that the folder is not locked (as this seems to be the default issue with the transparent/grayed symbol). Also the file permissions I can see via 'right click-->Get Info' are correct (I and can read+write, the group can read, everybody can read).
The terminal command
ls -l@ "/Volumes/Macintosh HD/Users" returns:
drwxr-xr-x@ next to my home folder, which is different from the default(?) permissions
drwxr-xr-x+. I followed the instructions here and here to reset permissions and remove all flags and extended attributes (there were 5 or 6 in total. Unfortunately, I did not write them down. Two of them had sth. like 'oldest time machine snapshot' and 'newest time machine snapshot' in their name).
That is (following the superuser post linked above), i did:
sudo chmod -N "/Volumes/Macintosh HD/Users/me" # Remove ACLs from file sudo chmod ugo+rw "/Volumes/Macintosh HD/Users/me" # Give everyone read-write permission to file sudo chflags nouchg "/Volumes/Macintosh HD/Users/me" # Clear the user immutable flag from file sudo chflags norestricted "/Volumes/Macintosh HD/Users/me" # Remove the SIP protection from file
followed by using the corresponding commands
sudo xattr -d com.apple.XXXYYYZZZ "/Volumes/Macintosh HD/Users/me" to remove all extended attributes, and finally followed by resetting the user permissions of the folder (as detailed here) via:
diskutil resetUserPermissions / `id -u`
This resulted in the permissions of my home folder becoming
drwxr-xr-x (no "+"!) and still the home folder is not accessible.
What could be other reasons for this behavior & how can I fix them? Alternatively: What would be my best alternative route to migrate the old user to the new system?
