El Capitan Synology

I feel your pain. I do not have a Synology, but SMB connections utterly failed for me after upgrading to El Capitan after working for years under Yosemite and earlier OSes.

After trying dozens of hours of various tweaks, I finally gave up and re-installed El Capitan via the Recovery Partition...and SMB stated working again for me.

Crazy.

OK wait! 10.11.3 may have fixed it for me!

Is still have the same problems with OSX 10.11.3 on a 13 inch Macbook Pro Retina Late 2013 (8GB Ram, 2,6 GHz). My Diskstation DS213 is visible in the finder and I can access it with "connect as..." but when I try loading folder content it says "folder XY count not be found".

Time Machine finds the volume as well and accepts user credentials but won't start the backup. I tried turning AFP and SMB on/off on the Diskstation, restarted both DS and Mac, turned file sharing options on the Mac on/off, but nothing seems to work.

I have exactly the same problem and have only just noticed as ive not had to use Lightroom where i store my photos on my Synology NAS since upgrading.

The folder is mounted connect when i re-boot my Mac but my Diskstation no longer shows under devices and Lightroom doesnt see the folders anymore on the NAS

So by remounting the diskstation as shown on the Synology page ive fixed my issue:

Any time I get a "folder xyz cannot be found" error, I restart finder and it works again. I usually have problems only after my laptop been sleeping. Doesn't usually cut out on me after I've successfully open a network folder and started using files within.

Turns out I still have problems under 10.11.3.

Apple's going the way of Microsoft. Getting too big for their britches. Power corrupts.

Hi All,

I have tried all the solutions, finally I get it work by setting on the Synology :

• Control Panel
• File Service
• SMB -> Advanced Settings
• Protocol to SMB 1 (using newer SMB protocols generate conflict with AFP)

Now I can connect to my synology using AFP within the finder 🙂

Hope it's help...

After trying all the earlier solutions, I arrived at the last one with little hope left. But it paid off to try anyway. Thanks @rdmendo!!

Neither of the above solution worked for me,

Just to share my workaround after hours of fixing:

Scroll down to look up Kirillius's post, what he said make sense n worked for me!

Goodluck.

I wish I had found your post earlier. Switching from SMB to AFP solved my issue as well - totally counter-intuitive, since Apple seems to be indicating that it will be retiring AFP in favor of SMB.

My issue:

I had been having major challenges on transfer speeds between my MacBook Pro running El Capitan 10.11.5 and my DS214 over 802.11ac. Transfers were taking minutes instead of seconds, and imports via applications like Lightroom were unbearably slow. I had been connecting with SMB3 and had fine performance with OS Yosemite 10.10.x.

Upon switching back to an AFP mount:

• Small file (1-2MB) writes have improved from 2.5MB/s to 15MB/s
• Large file (1GB) writes have improved from 15MB/s to 35MB/s

My conclusion? Apple continues to care not a lick about network storage. And it only took me yet another 10 hours of life to determine it.

I haven't tried turning off SMB entirely. That will be next.
