I was under Mac OS Sierra and first tought it was this upgrade which happend about the same time as the WD upgrade.
I am talking about accessing my files locally to my WD My Cloud shares. Simple. Nothing complicated. Just basic.
Thinking at first it was OS X...
So I reinstalled completely my iMac to El Capitan.
It was EXACTLY as slow. And when I say slow, I say reallllly slow.
The WD My Cloud is using a fix IP address.
I am accessing a public share. When I experienced this slow browsing and slow transfer speed, I tried :
- connecting to the share using smb://fix ip address/sharename, no improvement
- connecting to the share using cifs://..... no improvement
- connecting to the share using afp://..... no improvement
- switching the share to a private share and use the username / passowrd to connect to it... no improvement
- limiting WD My Cloud to smb2... no improvement
- limiting WD My Cloud to smb1.... no improvement
Having lost at least 2 days doing all this and reinstalling all my precious softwares I need for my business, I finally decided to try to downgrade the WD My Cloud firmware... BOOM. Everything is back to normal.
I am sorry guys, you just have to open a share on any iMac, you will experience this. It is obvious, and it does NOT depend on the OS X version, nor on the smb / cifs / afp connection.
Oh and BTW, my network is cabled. So no, it is not because of wi-fi.
I also have 2 PCs under windows... They were fine accessing the shares. So guys, your new smb protocole is not correct.
With this firmware, on Mac OS X :
-The more files there is in a folder, the greatest amount of time we wait in a blank finder screen for up to a minute or 2 before the finder starts displaying files.
-The files displays slowly (very very slow browing the files)
-The transfer speed is 20 times slower than before
-Working in lightroom switching between pictures is just not viable
I can tell you, people who will buy a WD My Cloud and working on Mac are going to throw back to you the device thinking the device is just not suitable for Mac. Which is false. It is a firmware problem... But new customers will not know they should downgrade and your reputation will be really bad for you regarding Mac's community... My 2 cents.
