Smb Server For Mac

Apr 10, 2020 Connecting your Mac to a server is an ideal way to copy files directly from one Mac to another, share large files, or access files from another network. You can connect to nearly any Mac or Windows server on your network as long as the. Connect to the server on your Mac. Now, on your Mac, from Finder's Go menu, choose 'Connect to Server.' Enter the IP address you just obtained from your PC, preceded by smb://, as shown.

1. Connect your Mac to shared computers and servers. You can connect to shared computers and file servers on your network, including Mac and Windows computers that have file sharing turned on, and servers that use protocols such as SMB. You can connect by either browsing or entering the computer’s or server’s network address.
2. Sep 04, 2016 SMB Windows file sharing not working on Mac after upgrading to macOS 10.13 High Sierra or macOS 10.12 Sierra or setting up a new Mac or MacBook via iCloud is easily fixed. For SMB windows file sharing, you need to select a user for activation.
3. This tutorial will walk you through connecting your Macs to SMB (Server Message Block) shares, hosted on Windows Servers, Windows Desktops, or network attached storage devices. Mac OS X allows you to connect to different network shares using the Connect to Server utility.

It's a common complaint that in recent versions of Mac OS 10.x, browsing Windows-hosted SMB shares is incredibly slow. Not every solution works, but here are 3 simple fixes that completely solved the issue for me (Using Windows Server 2012 & 2012R2 with Mac OS X 10.9 & 10.10).

3 Steps total

Step 1: Disable writing .DS_Store files to network shares

On the Mac, open up Terminal and enter the following command:

defaults write com.apple.desktopservices DSDontWriteNetworkStores true

Step 2: Make sure NetBIOS over TCP/IP is enabled on the file server's network adapter

Adapter Properties -> IPv4 properties -> Advanced -> WINS tab -> Enable NetBIOS over TCP/IP

Make sure this setting is enabled.

Step 3: Use Powershell to edit the server's SMB configuration.

On the Windows server, open Powershell as an administrator and run:

get-smbserverconfiguration

Look for the values for smb2creditsmin and smb2creditsmax. On my server, the defaults were 128 and 2048 respectively. To change these settings, run

set-smbserverconfiguration -smb2creditsmin 512 -smb2creditsmax 8192

and respond Y to the confirmation prompt.

Following these three steps instantly fixed the issue for me and others, and my Macs are now browsing the file shares just as fast as their Windows counterparts.

  Hey Chris, could you confirm that read and write speeds over SMB 3 on OSX 10.10 are the same as read and write speeds over SMB 3 on windows 8.1? Are you using 10gbe or 1gbe?

  We are using 10gbe and are seeing great read speeds (850MB/s) but not so great write speeds (400MB/s) even though our RAID can easily go up to 3,500MB/s.

  Thanks,

  Philipp

  Hi OSXUser, most (all?) RAID setups have inherently better read speeds compared to write speeds, and this has to do with the mechanics of RAID itself (see: http://www.raid-calculator.com/raid-types-reference.aspx). I suspect that if you benchmarked your Windows machines, you'd see a similar result to your Macs.

  Hi Chris,

  No the RAID actually gets 3,000 MB/s write. I can also hit it with multiple Macs each at 400MB/s write. The Windows server also has a PCI SSD with 2000MB/s read and write. The throttle seems to be on the LAN side.

  When connection one Mac Pro to another Mac Pro we get 800 MB/s read and write. But when connecting from Mac Pro to Windows Server the write is much slower than tge read.

  Any ideas?

  This solved the issue for me too. However, if use Hamachi to access the file shares from another country, I have to wait 2 or 3 minutes for the folders to show up. Then when the folders do show up and I open another folder, I have to wait again for those folders to show up.
  However, using Hamachi from a windows computer, there is no wait time for folders to show up.
  Any resolution for this?

  OSXUser, that's strange- but you're right, sounds like it's LAN stuff. And it sounds like you're not the only guy noticing this. I googled and found this- might have some ideas: https://social.technet.microsoft.com/forums/windowsserver/en-US/46898c7f-92e0-4c99-98d2-18a7458a7d2d/slow-network-write-speeds-via-smb-cifs

  Oscar3097, have you poked around to see if other Hamachi users have experienced the same issues? Sounds like a Hamachi issue to me.

  Chris, I thought this was a Hamachi issue but I discarded that idea because I can browse without a problem from windows computers. I have this problem when browsing from macs in Argentina, Puerto Rico, Panama, Brazil Mexico but not if they use windows. I had the same problem in the local lan, but using your fix we can now browse fast from all macs in the office.

  Hi Chris,

  I know this is an older thread but it is something I need to fix for two clients. I followed your excellent instructions and was successful for my Windows 2012 client, but when I run the set-smb... on a Windows 2008 R2 it says it isn't a recognized cmdlet. Any help that you could give me would be greatly appreciated.

  Hi kimcassidy, just saw this now- sorry for the late reply. I know that the ability to manipulate SMB through PowerShell was added with Server 2012; I'm not sure if you can upgrade your version of PowerShell or import the SMB module into 2008. Others might have more experience with this...

  I don't think this this is possible on Server 2008 R2. is it??

  I just made an account to praise you for writing this little article. It made my home theater set up go from struggling w/ 720p to streaming remux 1080p bluray with only occasional hiccups..

  It's still slower than I would think it would be given the pipes it's coming through, but at least it can handle the 2.77MB/s required to stream this big video.

  This seemed to do the trick here too.

  This worked for me....Took my searches from 3-5 minutes down to about 16 seconds. I'll take it!

  This worked for me, but then it didnt :/

  I was trying out a direct connection between my MBP and consumer Win10 machine connected direct via thunderbolt.

  They connected up nice and easily, and when running a test of disk speed from the MBP (with Blackmagic disk speed test) the internal drives on the Win machine tested at their full speed for around 500MB/s.

  However, external drives did not work - I was getting write speeds of around 5MB/s

  I ran across this page and when I enabled NetBIOS over TCP/IP this seemed to fix the issue - external drives mounted on the Win side would test at their capacity of 320MB/s when testing from the MBP.

  However, I have connected again a couple of weeks later and the network speeds have dropped back down to 5-6MB/s.

  I cannot for the life of me fathom what has changed, everything is still enabled on the windows side, and crucially this is only for externally mounted drives. The internal drives on the Windows machine still test at their full speed.

  Do you have any ideas?

  Hi,
  Any chance someone could provide some details on what each of these commands do.

  We are an office of some 100 users and i am hesitant to make changes to fix the issues for our 1 mac user if there is any negative effect for the 99 windows users.

  Thanks,

  Could someone confirm that this is still an issue with the newest Mac OSx?
