How to Mount a NAS Drive on Your Mac for Network Storage

Connecting a NAS drive to your Mac gives you centralized storage for backups, media libraries, and shared files. I’ll walk you through the basic connection process for SMB, AFP, and NFS protocols, plus practical solutions for keeping your NAS accessible.

Connecting via SMB (Recommended)

SMB is the most widely supported protocol for modern NAS devices and works reliably across different brands.

1. Open Finder and press Cmd+K (or choose Go > Connect to Server)
2. Enter your NAS address: smb://192.168.1.100 (replace with your NAS IP)
3. Click Connect
4. Enter your NAS username and password
5. Select the shared folder you want to mount

The drive appears in Finder’s sidebar under Locations. You can now access files as if they were on your Mac’s internal storage.

Connecting via AFP

Note: AFP is deprecated and will be removed in a future version of macOS. Use SMB for new connections whenever possible.

AFP works with older NAS devices and legacy file servers. The connection process is identical to SMB:

1. Press Cmd+K in Finder
2. Enter afp://192.168.1.100 (your NAS IP address)
3. Click Connect and enter credentials
4. Choose your shared folder

Connecting via NFS

NFS is typically used in Unix/Linux environments and may require additional NAS configuration:

1. Press Cmd+K in Finder
2. Enter nfs://192.168.1.100/volume1/share (adjust path to match your NAS export)
3. Click Connect

NFS connections may not prompt for credentials if your NAS uses IP-based authentication.

Making Connections Persistent

A NAS is a natural partner for Time Machine backups. You can point Time Machine directly at a NAS volume to keep off-site backups without an external drive.

To reconnect automatically at login:

1. Mount your NAS using any method above
2. Open System Settings > General > Login Items & Extensions
3. Click the + button under “Open at Login”
4. Select your mounted NAS volume
5. Click Add

Known Issue: macOS 26 has a known issue where NAS connections may drop after sleep or restart, even when added to Login Items. If you experience disconnections, you’ll need to manually reconnect.

Reconnecting After Disconnection

When your NAS disconnects, the fastest way to reconnect:

1. Press Cmd+K in Finder
2. Click the Recent Servers dropdown
3. Select your NAS from the list
4. Click Connect

Your credentials are saved in Keychain, so you won’t need to re-enter them.

Alternative: Third-party apps like AutoMounter can help automate mounting network shares at login and after sleep.

Troubleshooting Connection Issues

“Connection Failed” Error

• Verify your NAS IP address hasn’t changed
• Check that your Mac and NAS are on the same network
• Confirm the shared folder is enabled in your NAS settings

Authentication Problems

• Remove saved credentials from Keychain Access (search for your NAS IP)
• Try connecting again with fresh credentials
• Verify your NAS username and password are correct

Slow Performance

• Use a wired Ethernet connection instead of Wi-Fi when possible, as wired connections typically provide more stable and faster performance
• If your NAS is filling up, freeing up storage space on your Mac first can help reduce the load you put on it
