What this page covers
This guide explains the real reasons a Mac cannot connect to a network drive, the steps you can try yourself, and when it’s time to get professional on‑site help. It applies to:
• SMB network drives
• NAS drives (Synology, QNAP, WD)
• Shared Windows folders
• Shared Mac folders
• Office and home network storage
If your Mac refuses to connect to a network drive, shows connection errors, keeps asking for your password, or disconnects randomly, this page is for you.
The most common reasons a Mac cannot connect to a network drive
These are the issues that Keith Thomas identifies most often during on‑site visits:
• Incorrect SMB address
• Wrong username or password
• macOS SMB compatibility issues
• Network permissions problems
• Router or switch configuration issues
• NAS firmware issues
• macOS update problems
• Corrupted network settings
Quick checks you can do yourself
These steps solve around 60% of network drive connection issues.
Check 1 – Restart the Mac
A restart resets network and SMB services.
Check 2 – Restart the router or NAS
Most connection failures are caused by network devices, not the Mac.
Check 3 – Check the SMB address
Use the correct format: smb://servername or smb://IP-address.
Check 4 – Update macOS
SMB compatibility fixes are often included in macOS updates.
If the Mac cannot see the network drive
This usually means:
• Network discovery disabled
• NAS not broadcasting correctly
• Router isolation settings enabled
Try:
• Connecting using smb://IP-address
• Restarting the NAS
• Restarting the router
If the Mac keeps asking for your network drive password
This usually means:
• Wrong username or password
• Keychain conflict
• SMB authentication issue
Try:
• Removing old passwords from Keychain
• Re‑entering your credentials
• Restarting the Mac
If the network drive disconnects randomly
This usually means:
• Wi‑Fi dropouts
• Router sleep settings
• NAS power saving mode
Try:
• Using Ethernet instead of Wi‑Fi
• Turning off NAS sleep mode
• Restarting the router
If the Mac cannot connect after a macOS update
This usually means:
• SMB protocol changes
• Network settings reset
• Permissions issue
Try:
• Restarting the Mac
• Re‑adding the network drive
• Updating NAS firmware
If the network drive works on another Mac or PC
This usually means:
• macOS network configuration issue
• Corrupted preferences
• User account issue
Try:
• Testing on another user account
• Restarting the Mac
• Reinstalling macOS without erasing data
