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

Thank you
cifs doesn't help me. With cifs & smb networks shares work veeeeeeery slow and unstable :-(

Apple, make something!

I do not want come back to windows

So apparently mounting with cifs:// uses the SMB1 protocol instead of SMB2.

As I understand it, yes.

I am glad others are having success with cifs://

I have had no issues at all with cifs:// but still got issues with smb://

At the end of the day as long as something works i am very happy

Upgrading to 10.9.3 did not solve the SMB and / or cifs disconnect issues... 😟

...agreed: IMO this problem is all Apple

Thanks for the info PleasantSpectrum. Similar scenario here as well. So far 10.9.3 did not solve our SMB/CIFS issues.

...agreed: IMO This problem is all Apple.

I cannot believe im just being lucky with 30 macbook probretina and few old mac minis all with maverick able to use smb, ip, to mount shared folders.

i understand your frustration, but explain me how could it be an OS X issue if i can mount shared drive with SMB ?

Looks like it.

Somewhere in this thread there are some tips to set the Mac to use SMB instead of SMB2. You could try those as a start.

Bit hit and miss and not the fastest though.

Then there's this site: http://macsmbissues.com/

Their test config doesn't involve *any* Windows servers at all, just Linux servers running Samba..further evidence that this isn't a Microsoft issue.

@Kazop

Regarding issue 2. Do you experience Finder crashes when using the "quicklook" feature on multimedia files (video, photo, music)?

Still an issue in Yosemite. The command to force SMB1 works but the upload still suqs....

Very disappointing that SMB is not working in Yosemite... OSX seems to be bug ridden these days, what's going on Apple?!

What is your beef with Yosemite? It fixes the SMB issues.

Brilliant. I've been reading up on this for three weeks. This is the ONLY thing that worked. Thank you so much, my Friend!
