What this page covers
This guide explains the real reasons a Mac has slow internet, the steps you can try yourself, and when it’s time to get professional on‑site help. It applies to:
• MacBook Air
• MacBook Pro
• iMac
• Mac mini
• Mac Studio
If your Mac loads websites slowly, drops speed, buffers video, or feels slower than other devices on the same Wi‑Fi, this page is for you.
The most common reasons a Mac has slow internet
These are the issues that Keith Thomas identifies most often during on‑site visits:
• Weak Wi‑Fi signal
• Router or broadband issues
• macOS Wi‑Fi configuration problems
• VPN slowing the connection
• Background apps using bandwidth
• iCloud syncing delays
• Browser extensions slowing pages
• Damaged network settings
• Corrupted user account
Quick checks you can do yourself
These steps solve around 60% of slow internet issues.
Check 1 – Restart the Mac
A restart resets Wi‑Fi and network services.
Check 2 – Restart the router
Most broadband issues are router‑related.
Check 3 – Turn Wi‑Fi off and on
This forces the Mac to reconnect to the network.
Check 4 – Disable VPN
VPNs often reduce speed dramatically.
If the Mac is slow but other devices are fast
This usually means:
• macOS network configuration issue
• Browser extensions causing delays
• Background apps using bandwidth
Try:
• Restarting the Mac
• Testing another browser
• Closing apps like Dropbox, OneDrive, Zoom and Teams
If the Mac is slow only on Wi‑Fi
This usually means:
• Weak signal
• Wi‑Fi interference
• Router distance issues
Try:
• Moving closer to the router
• Restarting the router
• Forgetting and re‑adding the Wi‑Fi network
If the Mac is slow only on certain websites
This usually means:
• Browser cache issues
• Extensions slowing pages
• DNS issues
Try:
• Clearing browser cache
• Disabling all extensions
• Restarting the Mac
If the Mac is slow after a macOS update
This usually means:
• Spotlight indexing
• iCloud Drive syncing
• Network settings reset
Try:
• Leaving the Mac plugged in for a few hours
• Restarting the Mac
• Updating all apps
If slow internet affects only one user account
This usually means:
• Corrupted user account
• Damaged network preferences
• Permissions issues
Try:
• Testing internet speed on another user account
• Restarting the Mac
• Reinstalling macOS without erasing data
