Zac Bowden at Windows Central:
Microsoft today confirmed plans to rebuild its Edge browser using Chromium, in a move designed to improve web performance and app availability across platforms. Windows Central reported earlier about the shift in strategy and now it is official.
The new version of Edge is expected to start shipping as a beta in the coming months, and will run on Windows 7, 8, 10 as well as macOS. With Chromium under the hood, users should can expect a better and faster browsing experience than Edge or IE before it could ever offer.
Microsoft Edge coming to the Mac will be the first time Microsoft's flagship browser has been on the platform since Internet Explorer 5.2.3, 15 years ago
