Configure macOS's built-in SMB server (com.apple.smb.server) — settings apply only when committed via SCPreferences, never via defaults write. Use when a Mac's "Macintosh HD" or a home folder is visible to other machines on the LAN (virtual shares), when disabling guest access on file shares, when a com.apple.smb.server change doesn't take effect, or when proving server-side which shares a Mac offers.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# macOS SMB server (com.apple.smb.server)
Validated on macOS 26 (Darwin 25.6), Mac mini M2, 2026-08. Two facts drive everything here:
- **Virtual shares**: beyond the explicit sharepoints, smbd automatically offers every mounted
volume to admin users ("Macintosh HD", external drives) and each authenticating user's own home
folder. They never appear in System Settings or `sharing -l`, so they can't be removed there.
- **Commit, don't write**: smbd never reads
`/Library/Preferences/SystemConfiguration/com.apple.smb.server.plist` off disk. A `defaults
write` there is invisible until reboot. Changes apply only when committed through the
SCPreferences API, whose commit fires the `com.apple.smb.preferences` launchd event that runs
`/usr/libexec/smb-sync-preferences`.
## 1 — Classify what clients see
`sharing -l` lists the explicit sharepoints and their per-share guest flags. Anything a client
sees beyond that list is a virtual share. Done when every share visible from a client is
classified as sharepoint or virtual — the two are fixed by different mechanisms.
## 2 — Change settings

How to install
mdr add soulmachine/skills/macos-smb-server@sha256:1eca12046e075f6dThe line at the top of this page pins the label git:20260831.964a54b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
