Sharing a container over SMB

If you would like to share an iodyne container from Pro Data or Pro Mini to another computer over the network, you can do so with the file sharing built-in to your operating system. Below are instructions on how to do that for macOS.

macOS SMB Sharing

Add User Accounts

1. System Settings → Users & Groups → Unlock.
2. Add User → Change Standard to Sharing Only.
3. For read-only access: Account Name: share_ro 
4. For read-write access: Account Name: share_rw

Grant Full Disk Access

1. Settings → Privacy & Security → Full Disk Access.
2. ＋ → ⌘ ⇧ G → /usr/sbin/smbd → toggle ON.
   1. macOS will auto-enable Allow full disk access for all users – leave it on.

Share Desired Containers

1. Settings → General → Sharing → File Sharing ︎→ Toggle On
2. Click the ⓘ next to the File Sharing
3. Shared Folders ＋ → select your container(s)

5. Choose Registered User
   1. For read-only access:

      2. Password: (what you set above)
   3. ✓ Remember this password in my keychain → Connect.
6. A list of shares appears — highlight SMB_Test → OK.

Optimize SMB Performance (Optional)

For optimal performance when hosting SMB shares from macOS, we recommend applying the following SMB performance tunables on the host Mac.

These settings optimize SMB behavior for dedicated media workflows and should only be applied to Macs that are acting as the SMB host.

Note

• Apply these settings only on the Mac hosting the SMB share.
• Administrator privileges are required.
• Restart the Mac after applying or removing the configuration.
• If the Mac is no longer being used as an SMB host, restore the default configuration by removing the custom tunables.

Tip: triple-click anywhere inside a code block to select the entire command, then press ⌘C to copy it.

Apply the SMB performance tunables

1. Open Terminal.
2. Run the following command:

   • sudo bash -c 'printf "%s\n" "[default]" "signing_required=no" "streams=yes" "notify_off=yes" "port445=no_netbios" "protocol_vers_map=2" "unix extensions = no" "veto files=/._*/.DS_Store/" > /etc/nsmb.conf'

3. Restart the Mac.

Restore the default SMB configuration

If the Mac will no longer be used as an SMB host, remove the custom configuration.

1. Open Terminal.
2. Run the following command:

   • sudo rm /etc/nsmb.conf
