Can't Mount SMB/CIFS Shares in OS X Sierra Public Beta 4

Of note, just in case:

http://kb.netgear.com/app/answers/detail/a_id/24923/~/readynas-os-6%3A-smb-plus-app?cid=wmt_netgear_organic

"ReadyNAS OS 6 supports SMB protocol 3.0 by default."

So there's that, for people that are out of warranty - a newer device should work without issue, it looks like, or at the very least has the proper protocols in place to be supported.

Hmmm... now I am being told AFP was *not* removed in macOS Sierra:

https://support.apple.com/kb/PH25269?locale=en_US

Apologies as I knew that. It wasn't removed. The only difference between you and I seems to be that you can browse via SMB and I can't. I can authenticate to both protoclos and see directories but never see any files. 

Yeah, the commenter on the Apple Discussion boards was talking out of his butt, so that was bad information.  Argh....

The consistent thing I am seeing is a problem with Authentication... AFP forces me to manually reconnect and authenticate each time I want to mount a share.  Time Machine never asks me for credentials, and just fails when trying to connect, presumably because it can't authenticate.  This does sound more like a bug, and less like intentional.

ovrdrvn - try removing all references to authentication to your NAS from your Keychain, see if that clears it up and lets you reconnect, at least by hand?

I have already connected to AFP shares on my OS6 NAS. I'm yet to try Time Machine but I can see the Time Machine disk. I'll give it a try today.

ReadyNAS OS 6.6.0 has the latest version of Netatalk (AFP/Time Machine service for Linux). We are using samba 4.4.x (SMB service for Linux) currently and will continue to evaluate the changes in new versions and decide when to update to newer versions of samba. OS6 is designed to make upgrading these packages as straightforward as possible. We keep these much more current in OS6 than many of our competitors.

Unfortunately Apple has a poor track record of breaking compatibility with older NASes with their software updates and not taking responsibility for fixing what they broke.

I will need to have a look at one of my 4.2.x systems at some point and try and see if there are any workarounds.

Just tested Time Machine backups with Sierra and ReadyNAS OS 6.5.0 (which we released some time ago now, the latest OS6 firmware is 6.5.2) and it's working fine for me.

Running a full (i.e. first) backup now.

I did some experimenting last night, with interersting results.  The plot thickens...

I did the following:

• Removed all references to my NAS from my Keychain
• Removed all mounts, and rebooted.
• Went into the NAS Admin Panel, disabled, and re-enabled AFP on all my shares.

Once I did this, the following things happened:

• SMB is not working - I am getting an error that the device could not be found.
• AFP works fine, once I authenticate for the first time.
• I am unable to connect to the Time Machine that is included with the NAS.  However, if I set up an individual home folder and configure it to be a Time Machine location, and authenticate using that, it works fine - as long as I authenticate using that specific user's credentials.
  • I had specifically done this in the past because I have 4 Macs in my home, and I didn't want one of them crowding out the others.  This way, each Mac has its own dedicated disk space for the Time Machine backup, and one won't compromise another's backup.

It looks to me as if the main issues are: 1) SMB, and 2) Authentication to multiple points on the same NAS using different credentials by Sierra.

Edit: This is how I set up a share as a Time Machine location for a specific user:

Did you try both the IP address and the hostname?

Perhaps try disabling SMB signing on your Mac. SMB signing is now required by default by Sierra.

Didn't work for me but here's how to do it for anyone else wanting to try:

printf "[default]\nsigning_required=no\n" | sudo tee /etc/nsmb.conf >/dev/null

Any updates from Netgear on this? I have strange performance with AFP (testing more to see how useable it is or not) and CIFS/SMB I can't see any files...only directories. 

ovrdrvn please check what difference reverting the SMB setting change makes.

This disn't help at all. I still have no SMB access, no Time Machine abilty and some AFP access (peformance isn't great and one large volume seems inaccessible but I suspect it's a time out issue)
