Hi all,
I updated my iMac to Sierra 10.12; so far everything seemed OK, even my own programs.

BUT ... my remote connections (via AFP) to my other machines fail since then.
It appears that the directory /Volumes which looked formerly (I think over many years):

drwxrwxrwx@ owner=root, group=admin

suddenly looks:

drwxr-xr-x@ owner=root, group=wheel

So, without a chmod I can't put mount points in there.
Of course I could sit somewhere else and mount my remote systems on a directory in there,
but some of my programs conform to the standard that all mounts are in /Volumes.
Does anybody know if the change in 10.12 is a measure against some security problem?
Should I just change the mode of /Volumes back to drwxrwxrwx? Or should I make my own?
Need some advice.
Thanks for reading this and thinking it over.
;JOOP!

As Disk Utility would reset all permissions to normal, changing /Volumes is no option.
So I created my own /Volumes in my home directory and rewrote all associated software.

It's also not a good idea to change ownership on directories created by the system. Doing so can lead to unexpected results from the operating system or other applications. Apple changed /Volumes to be owned by root to improve security. Refer to https://forums.developer.apple.com/message/169554 for more information

Thanks for the link (I'm not alone).
Still it would be great if APPLE would add some info with new updates.
This is not the way to find out; I'm retired, but I must not think
of still working on a project and then clashing with this kind of stuff.
Remember that umask was dropped in Mavericks?
Little changes that kill your deadlines.
Thank Heaven for forums like these.
;JOOP!
