How to use Microsoft Edge in mac?

There is no version of Microsoft Edge that runs natively on Mac OS X.

However, we do have some options in the works to help Mac users test their sites in MS Edge.

1. We provide pre-configured Windows 10 VMs that are ready to run and test Microsoft Edge. They are available at: http://dev.modern.ie/tools/vms/mac/. You can read the announcement here.
2. We have a cloud streaming version (previously "RemoteIE") that we are going to upgrade to Microsoft Edge. This will take us a bit longer due to Azure changes needed but will be available at http://remote.modern.ie.

Now that Edge is based on Chromium, the Beta and Dev Channels have builds of Microsoft Edge for Mac OS. The installer can be downloaded from Microsoft Edge Insider Channels.
