Q: 10.9.2 Mavericks and can no longer connect to our SMB file share on the network.

Yes my smb is not working

Since i upgraded to 10.9.2 i cant access network shares

It shows them empty or thriple directories

My operating system is becoming very unstable

This is the first time this has happened from an update

DO NOT UPDATE ITS REALLY BAD

My SMB shares are accessible just as fine as before with 10.9.2

Did you try to connect with IP address ?

Yes I always connect through ip

i work at multiple sites and this is a BIG problem for me

As i said, it's working fine for me so im not sure we can assume its an update to 10.9.2 related issue.

I have had apple from 10.6 & never had this issue

joekmaclinux has it so YES after the update the issue happened

If you arent affected your lucky but FROM 10.9.2 MY SMB IS STUFFED

Have the same problem after upgrade to 10.9.2 :-(((((((

Can i downgrade to 10.9.1?

Same happening here... upgrade to 10.9.2 makes the cifs:// and / or SMB:// shares disconnect!

Within a multinational NOT acceptable!

please supply either a downgrade to 10.9.1 or a solution!!

Count me in on this one. Any suggestion for a temporary fix?

You will find many posting regarding SMB2 connections since 10.9.2. I'm affect too. There are some workarounds floating through the forum but in reality it doesn't work. So we will have to wait until Apple is thinking this is a priority issue.

Did some snooping around and found this (thanks to the tip of surogat70 that this could be SMB2 related) -> http://hints.macworld.com/article.php?story=20131122083837447

You can change the new default system behavior that uses SMB2 protocol back to SMB. Seems to work for me anyways. I can mount my network drives again.

Not very stabile though. The disks unmount themself's after a certain time not being used it seems.

I can life with it for now. But please fix this ASAP Apple. It seems that it becomes a trend that with every "up"date of osx something very essential for me is breaking. It's becoming a nuisance. 

I didn't know about the SMB situation before this. But being able to browse network storage is for some mission critical! Don't implement new protocols that aren't fully and reliably working.

Same story here - smb:// worked under 10.9.1, but the Update 10.9.2 broke it.

Some facts:

• Mac Book Pro Retina 2012
• Network connection is over WLAN (The connection is very stable and no issues else where)
• The issue seems to be caused when there are larger files (> 500MB) in the share
• smb:// works for shares with lots of folders but only small files in them
• smb:// and cifs:// are both almost unusable
• smb://  shows a blank screen for ages- Finder will eventually hang up
• cifs:// will connect fast (wow!), but the connection is very unstable for larger files

The funny part is, that Mavericks (pre 10.9.2) was the first OS X which fixed most SMB issues of its predecessor. (SMB2 was somwhat slow, but quite usable) Now, I can not really use my Mac to work...

Moral of the story, I think I will switch to Ubuntu 14 when it is released in April - it should support HDPI Displays.

In my case, things happen with all the files (my shared folders are constituted by small files like "pdf", "doc", etc.)

Sorry don't have any tips for you. But I also have a lot of trouble with the "quicklook" function when using it on network storage.

If I use quicklook on a file (.pdf, .mp3, mp4, txt, etc, etc, etc), the finder instantly crashes. This is a serious disturbance in my workflow.

Reading your problem I think these two are related (although I didn't check logfiles, at the moment I have a little bit of a "why bother" attitude towards Apple bugs).

Apple spent so many years to build themselves up, to challenge the pc market

Five mistakes which puts their head in the sand

1) 10.6 Rosetta gone

2) Java so screwed

3) Server going down hill

4) New OS every year

5) This smb issue

Even like the ipad no flash - Why????

We do our head in for third party apps

Really starting to consider the pc

I might suggest it to all my work sites to stay clear from apple

Being a network administrator for 5 sites, there issues become my

Apple do yourself a favour & really think about what your doing?

What you have achieved & stop acting like top cop.

Your product is good but not that good

I been using Windows 8.1 but you install the classic shell & it works really really well.
