Microsoft today officially launched its first preview build of the new Edge browser for macOS. Though Mac builds were previously leaked, this marks the first official release from Microsoft. Microsoft is expected to add those features to the Mac release later this year. If you’re interested in checking out Edge for macOS in preview form, it’s free to download.
After a 15-year hiatus, Microsoft has officially returned to the macOS browser scene, as its Edge browser is now available for Mac users to download. There’s only one hitch: Edge is currently available in two separate pre-release forms, daily and weekly, and even the typically more stable weekly version is fairly crash-prone.
Based upon Google’s Chromium, the Edge project for macOS was announced in December 2018 alongside Windows 7 and Windows 8 versions of the browser, and preview builds were promised for an “early 2019” release. Even though Edge is arriving a little late, fans will be glad to see support for Edge extensions from the Microsoft Store and multiple user profiles, as well as Mac-specific Touch Bar support for tab switching, and slightly tweaked rounded tab corners. Unfortunately, macOS Mojave’s Dark Mode is not yet supported.
While the browser’s current functionality is solid, it doesn’t include some of the Edge enhancements Microsoft announced yesterday, such as superior privacy tools or support for Collections — automated, AI-assisted gathering and organization of content you’ve browsed. Microsoft is expected to add those features to the Mac release later this year.
If you’re interested in checking out Edge for macOS in preview form, it’s free to download. As of today, there are two versions to explore: a daily Canary build and a weekly Dev build. In our testing, the Dev build crashed on a macOS Mojave installation within several minutes of its first load and exhibited issues displaying some content from the VentureBeat home page. Hopefully these problems will be fully fixed in future builds.

Note
This article applies to Microsoft Edge version 77 or later on Windows 8 and Windows 10. For Windows 7 and macOS, see the Set Microsoft Edge as default browser policy.
Introduction
You can use the Set a default associations configuration file Group Policy or the DefaultAssociationsConfiguration Mobile Device Management setting to set Microsoft Edge as the default browser for your organization.
To set Microsoft Edge Stable as the default browser for html files, http/https links, and PDF files use the following application association file example:
Note
To set Microsoft Edge Beta as the default browser, set ApplicationName to 'Microsoft Edge Beta' and ProgId to 'MSEdgeBHTML'. To set Microsoft Edge Dev as the default browser, set ApplicationName to 'Microsoft Edge Dev' and ProgId to 'MSEdgeDHTML'.
Note
The default file associations aren't applied if Microsoft Edge isn't installed on the target device. In this scenario, users are prompted to select their default application when they open a link or a htm/html file.
Set Microsoft Edge as the default browser on domain-joined devices
You can set Microsoft Edge as the default browser on domain-joined devices by configuring the Set a default associations configuration file group policy. Turning this group policy on requires you to create and store a default associations configuration file. This file is stored locally or on a network share. For more information about creating this file, see Export or Import Default Application Associations.
To configure the group policy for a default file type and protocol associations configuration file:
- Open the Group Policy editor and go to the Computer ConfigurationAdministrative TemplatesWindows ComponentsFile Explorer.
- Select Set a default associations configuration file.
- Click policy setting, and then click Enabled.
- Under Options:, type the location to your default associations configuration file.
- Click OK to save the policy settings.
The example in the next screenshot shows an associations file named appassoc.xml on a network share that is accessible from the target device.
Note
If this setting is enabled and the user's device is domain-joined, the associations configuration file is processed the next time the user signs on.

To set Microsoft Edge Beta as the default browser, set ApplicationName to 'Microsoft Edge Beta' and ProgId to 'MSEdgeBHTML'. To set Microsoft Edge Dev as the default browser, set ApplicationName to 'Microsoft Edge Dev' and ProgId to 'MSEdgeDHTML'.
Set Microsoft Edge as the default browser on macOS
Attempting to programmatically set the default browser on macOS causes a prompt to appear for the end user. This prompt is a macOS security feature that can only be automated away by using an AppleScript.
Because of this limitation, there are two main methods for setting Microsoft Edge as the default browser on a macOS. The first option is to flash the device with an image of macOS where Microsoft Edge has already been set as the default browser. The other option is to use the Set Microsoft Edge as default browser policy, which prompts the user to set Microsoft Edge as the default browser.

When using either of these methods, it is still possible for a user to change the default browser. This is because for security reasons, the default browser preference can’t be blocked programmatically. For this reason, we recommend that you deploy the Set Microsoft Edge as default browser policy even if you create an image with Microsoft Edge as the default browser. If the policy is set and a user changes the default browser from Microsoft Edge the next time they open Microsoft Edge, they will be prompted to set it as the default.
