I am trying to run Docker on an old Mac OS.

I get this error:

Error setting up host only network on machine start: VirtualBox is configured with multiple host-only adapters with the same IP "192.168.99.1". Please remove one

The issue came from having run docker on two different sessions on my machine.

To fix it I ran: VBoxManage list -l hostonlyifs to identify adapters, and then removed the one I didn't need anymore:

VBoxManage hostonlyif remove vboxnet1

Alternatively, if you want to be able to run Docker from two different sessions, you can change the IP address of each adapter:

  • Go to File -> Host Network Manager
  • Change the IP address of one of the adapters

I had this same issue come up as well when using Local by Flywheel.

I have two different user accounts on my Mac. One for personal, one for work. I was still logged in to my work account when trying to start up a machine on my personal account.

After making sure I was completely logged out of my work account and restarted, I was able to get it working again on my personal account.

Before doing this I noticed that my IPv4 Address/Mask under Host Network Manager was the same. After having logged out and restarted, it is now different and I no longer am getting the notice when starting Local by Flywheel.

Hope this helps someone out!

This Error happens because you have already virtualbox installed in your computer.

Here is the simple step.

Step 1: Uninstall Virtualbox from Your Computer

Steps 2: Uninstall Docker and Re-Install It

Fixed!!!
