League of Legends lag on Mac: check ping and packet loss

Lag can come from the game service, the route to it or your local network. Test each before changing settings.

Applies to: League of Legends on macOS.Checked: 2 November 2026

Symptoms

  • The game displays Attempting to Reconnect.
  • Players jump or actions respond late.

Likely causes

  • A service or route issue. A game service incident or a problem on the path can interrupt play.
  • Local network contention or interference. Other traffic and Wi-Fi interference can contribute to delay or loss.

How to check

  1. Check Riot’s service status for your region.

  2. Check your account region in Riot’s regional server guide. Regions and transfers can change.

  3. Test in a custom game to avoid a penalty during troubleshooting.

  4. Use Riot’s connection log reader to inspect a recent match.

  5. Compare Wi-Fi with Ethernet if possible. See Test for packet loss on a Mac with ping.

  6. Riot lists UDP ports 5000–5500 and 7000–8000 for the game client. Ask your network administrator about restrictions.

How to fix it

  1. Pause large downloads and test again.

  2. If Ethernet helps, check Wi-Fi signal and interference. See Weak Wi-Fi signal on a Mac.

  3. If the problem continues, use Riot’s support steps and provide the requested logs.

With Kilobat

  1. Run a general connection test. A ping result does not prove the game server is healthy.

Questions

Is a high frame rate the same as low latency?

No. Frame rate measures rendering; latency measures network delay.

Can a general ping test prove Riot’s servers are healthy?

No. Check the game’s own status and match logs as well.

Does League require a particular NAT type?

Riot’s cited connection guide does not specify a NAT type. Check its current support guidance before changing router settings.
