Fix slow OS X El Capitan / macOS Sierra download speed

A lot of people, including us, have been getting really slow download speeds on the OS X El Capitan, or macOS Sierra, download. Chances are, the servers nearest to you are being seriously hammered, hence the slow download.

An easy fix to this is to change your DNS to either use OpenDNS or a free DNS from the land down under (Australia)

Go to System Preferences > Network > Advanced > DNS remove any existing DNS entries and add either of the following: #OpenDNS

# We've had success with the one above, the following DNS worked for some but was down when we tried it, give either one a shot to see which one works for you.

Pause your download, give it a minute and then restart it.

Bandwidth consumption jumped to almost completely consume the connection we had immediately.


  1. Dear god thank you so much! There’re advices to change the DNS server all over the internet, but this is the first one that actually worked for me.

    • Try adding the DNS entries to the dhcp area on your router so your computer automatically fetches them when it connects to the network

      • It was a fresh install on a newly-formatted drive. Those components were not available for edit. Managed to finish in less than 30 hours. 🙁

  2. Don’t forget to click ‘Apply’. Works great. I added both DNS and speed went from 1 day to 30 min.

  3. (Update for July 2016) Thank you, the OpenDNS above worked for me. ( The other one must’ve borked after being hammered from being spread on Reddit and everywhere else.
