Not only was Edge originally a Windows 10-only browser, but it sees a Microsoft-made web browser available on a Mac for the first time since Internet Explorer - and that was 16 years ago, when Microsoft ceased the updates. The fact that Microsoft is releasing its Edge web browser on macOS is remarkable for a few reasons. We’ve already heard about new features coming to the new Chromium-based Edge web browser during Microsoft’s Build 2019 developer conference, so we could hear more about the Mac version of Edge soon. Microsoft confirms Edge will be able to use Google Chrome Extensions.
