I lost access to my NAS share drive since EL Capitan

How do you enter you ID and Pasword with the cmd+K ?

I've been experiencing these headaches since Yosemite.

The quickest method that i've discovered to resolve this is to simply unplug/replug the ethernet cable. (or disable/enable wifi connection if you're connected via wifi.)
This resets the connection and relinks the NAS devices as it should.

CMD+K and typing the IP manually also works.
Restarting the computer also works.
Restarting the NAS devices also works.

Pretty much any method that Unlinks and Re-links the NAS devices to your MAC.

I've done tons of research and there are many people that are experiencing these issues.
On reddit some place someone explained to me that Apple changed the way they handled some network related connections in Yosemite and it hasn't been the same since.

I've also found that if you leave the connection open it doesn't seem to go offline.

I've also been having issues accessing my other Macs from the same "shared" section (file sharing/screen sharing etc).
I'm almost certain that they're related.

Hope this helps.

This is a different problem. But thx anyway.

Thank you very much for finding a solution for one user, but i need a fix for more than one. Current system is a Ubuntu 14.04 LTS with netatalk and avahi. Is there a solution for more than one user?

Cheers

Simply. After you enter the url, a dialog window appears and you can choose to connect as a guest or type a user name and password.

Different? How so?

Same issue described by the OP.

Never experienced under Yosemite. None of your solutions does work.

Hi

same issue on 10.11 with Lacie big2 nas, latest FW.

No acces thru finder, OK thru "connecting server" smb://+ IP or cifs://+IP

do you have any idea how I could use your tip on my mac?

hope Apples gives out a patch soon!

bye

I am having a similar issue. I just upgraded my Mac Mini to El Capitan from Yosemite and now I can no longer see my networked drives that are connected to the server and shared via File Sharing. Never had any issues with this in Yosemite. This is not good 😟

I have a Sinology NAS and like many others here, after the El Capitan update seemed to have no other whey then CMD-K getting into my NAS' shares. However, it seems that my mac just simply needed a WINS reset, perhaps yours is fixed with this also. Try this:

1. Open system prefs

2. Select Network

3. Press Advanced (button in right corner)

4. Select WINS tab

5. Select a Workgroup. My mac shows 'homegroup' as well as 'workgroup' selecting either one seemed fine

6. Click OK

7. Click Apply and dismiss dialog

Now select your NAS icon in Finder and it should show you all the shares on that NAS.

I am having exactly the same issue with my Sinology NAS, let's hope apple find a fix soon.

@Yvonne; did you try/follow the steps? Thats the solution (at least for me).

I tried to system changes but no different for me, maybe I missed a step

I'm actually trying to install a new Buffalo LinkStation NAS, but judging by the previous posts, creating a home network with El Capitan is **** near impossible. I'm really ******, not only because I've tried everything in the previous posts with no success, but because I can't help but think that Apple is making things difficult so as to become so proprietary, that using other brands will no be an option. My fingers are crossed that this is a legit bug and not some crazy conspiracy. So far I've tried the Nav 2 software included with the NAS, the workgroup thing, the sub net thing, killing the finder, using cifs protocol when connecting via the IP, and everything _sub suggested even though I knew it wouldn't work. The NAS sometimes appears in the Shared section, but it has never connected. Any other suggestions?

Same problem too! please fix it apple
