Mount a NAS over SMB as a Local Drive on Mac with OurClone

Learn how to mount a NAS share over SMB as a local drive on macOS using OurClone — browse, edit and upload your NAS files as if they live on your Mac.

Overview

A NAS on your network holds terabytes of shared files, and mounting it over SMB through OurClone brings those files into Finder with a consistent mount workflow and local caching. This guide shows how OurClone connects to a Synology, QNAP, or Windows share and mounts it as a live local volume on your Mac.

Why Mounting a NAS over SMB on macOS Is a Smart Move

SMB is how macOS talks to a Synology, QNAP, or Windows share, and OurClone wraps that connection in the same mount workflow it uses for cloud storage — with local caching and a read-only option. Mounting your NAS this way puts its files in Finder while keeping management consistent alongside your cloud mounts.

  • 🗂️ Native Finder Access -- Your NAS share shows up as a normal macOS volume across every app.
  • 💾 Cache Only What You Open -- OurClone caches recently used files locally instead of copying the whole share.
  • 🔁 Live Two-Way Access -- Edits in the mount write back to the NAS; changes from other devices appear after the next poll.
  • 🛡️ Read-Only Safety -- Browse a shared media library read-only to prevent accidental changes.
  • LAN Speed -- Because the NAS is on your network, reads and writes aren't limited by your internet connection.

How Mounting a Cloud Drive Works (and Why It's Different from Sync)

Sync copies every file down to your Mac and keeps both ends matched. A mount leaves files on the NAS and streams them to your Mac as you open them, backed by a local cache.

OurClone manages reads, writes, and change detection so recently used files stay quick while the rest of the share waits on the NAS until needed.

You can mount an SMB share with a configurable polling interval and cache size, plus a read-only option for safe browsing.

  • 🚀 Stream files on demand — no need to copy the whole share
  • 💾 Saves Mac disk space by caching only what you actually open
  • 🔁 Two-way sync — edits in the mounted folder write back to the NAS
  • 🛡️ Read-only mode prevents accidental writes when you only need to browse

What to Know Before You Mount Your NAS

A little prep keeps the mount stable.

  • 🧩 Install macFUSE First -- OurClone's macOS mount relies on macFUSE; install it once before mounting your NAS.
  • 🌐 Confirm the NAS Address and SMB -- Have the NAS hostname or IP (e.g. 192.168.1.100) ready, make sure SMB is enabled on the NAS, and that your Mac is on the same LAN with port 445 open.
  • 📁 Pick the Right Mount Source -- Mount a single shared folder for focused access, or a broader share for full browsing.
  • 🖥️ Choose a Sensible Mount Point -- Use a dedicated empty folder like ~/CloudMounts/NAS, not your Desktop or a populated folder.
  • 🔒 Read-Only vs Read-Write -- Read-only suits browsing; read-write is needed to upload, edit, or delete. Read-only mounts can't upload.
  • 💽 Plan Your Cache Size -- A larger cache speeds repeat access but uses local disk; size it to the files you open most.

How to Mount a NAS over SMB on macOS with OurClone

OurClone connects to your NAS over SMB, then mounts the share as a local volume.

  • 🔗 Connect Your NAS via SMB -- Open OurClone and go to Add Storage. Select SMB. Enter the IP address or hostname of your NAS (e.g. 192.168.1.100), along with your username, password, and port (default 445). Once connected, your NAS share appears as a storage destination.
  • Add SMB NAS to OurClone
  • 📂 Open the Mount Tab and Click New Mount -- With the NAS connected, go to the Mount tab and click New Mount in the top-right corner.
  • Open New Mount Dialog in OurClone
  • ⚙️ Configure the Mount Settings -- Pick your SMB connection as the source. Choose a specific shared folder or the whole share, then a local mount point like ~/CloudMounts/NAS. Select Read-only or Read-write, optionally adjust polling interval and max cache size, and click Mount.
  • Configure Mount Settings in OurClone
  • 🗂️ Use Your NAS Mount Like a Local Folder -- Open the mount point in Finder. It behaves as a mounted volume — browse, open, create folders, drag in files, and delete items (when read-write). Add a backup folder and a few files; OurClone writes them to the NAS in the background.
  • NAS Mounted Folder on macOS Finder
  • Confirm the Sync on the NAS -- Back in OurClone, open the SMB storage in the file browser to see the new backup folder. You can also open the NAS web interface (DSM or QTS) and confirm the files appeared in the share.
  • Verify NAS SMB Mount Sync

An SMB connection plus OurClone's mount engine turns your NAS into a native-feeling drive on macOS, managed alongside your cloud mounts.

Getting the Most Out of Your NAS Mount

Keep these in mind once your NAS mount is live.

  • 🔁 Edits Sync Both Ways -- Adds, renames, and deletes in the mount write to the NAS; changes from other devices appear after the next poll cycle.
  • 🛑 Read-Only Means Read-Only -- A read-only mount blocks uploads and saves. Remount read-write to make changes.
  • 💽 Cache Lives on Your Mac -- Recently opened files are cached locally; lower the max cache size if disk space is tight.
  • ⏱️ Polling Interval Affects Freshness -- On a fast LAN, a short 15–60 second interval keeps the mount fresh without much cost.
  • 🔌 Unmount Cleanly Before Sleep -- OurClone reconnects on wake; for long breaks, click Unmount to release the volume.

When Your Mount Stops Working

NAS mounts usually break when the device's IP changes, its account password is updated, SMB is disabled, the Mac leaves the LAN, or the mount point is no longer empty. A reserved IP and a dedicated account keep things stable; confirm the NAS is reachable on port 445, then remount.

Verify the Sync Anytime

When in doubt, open the SMB storage view inside OurClone or sign in to the NAS web interface to confirm your files.

Summary

Adding an SMB share with the NAS hostname, username, password, and port 445, then creating a new mount in OurClone, turns the share into a local volume on macOS. Choose read-only or read-write, tune polling and cache, and every change in the mounted folder syncs transparently back to the NAS.
