How to Reset Hosts File to Default on Mac and Windows PC

When you encounter an iTunes error like 3194, network failures, or connectivity issues, it is recommended to edit the hosts file. If you have updated the file many times, the original version is gone. Of course, you would have ideally created a backup copy of the original, but in the event that you didn’t, here’s how to reset the hosts file to default in macOS and Windows.

What is the Hosts File? 

The simplest explanation is that it is a text file used by your computer to map a connection between an IP address and domain names. It can be edited to test certain network aspects or to troubleshoot connectivity issues. Of course, you should keep a backup of it before editing. But in case you do not, you can still recover the original version as explained below.

  1. Open Notepad on your PC
  2. Go to this page and copy the text of the hosts file for your OS version. Different hosts file contents exist for different Windows versions (although they vary slightly)
