Help with time machine restore file permissions

[dellsweig]

I have restored some user files fromm a time machine backup to a new disk on an IMAC runing Big Sur

The restored files have user but wrong group permissions

the group is set to _analyticusers and should be staff.

When I try a chggrp as root from the shell i get the following:


bash-3.2# man chgrp


bash-3.2# chgrp -fR staff *


chgrp: Desktop: Operation not permitted


chgrp: Documents: Operation not permitted


chgrp: Downloads: Operation not permitted

Here is what the permissions look like

bash-3.2$ ls -l

total 0

drwx------@ 54 dellsweig _analyticsusers 1728 May 12 2022 Desktop

drwx------@ 81 dellsweig _analyticsusers 2592 Apr 7 2022 Documents

drwx------@ 7 dellsweig _analyticsusers 224 Dec 23 2020 Downloads

drwxrwx---+ 51 dellsweig staff 1632 Jun 2 2022 Library

drwxr-xr-x 4 dellsweig staff 128 Oct 13 2020 Movies

drwxr-xr-x 3 dellsweig staff 96 Jul 25 2020 Music

Any ideas??
