TL;DR: Microsoft once swore it would never support Google's services in Edge by default. Now, with caveats, it's doing exactly that, on both Windows and macOS.
Microsoft latest release of the Edge browser adds a much-requested feature for users working within Google's web ecosystem. Edge 150 finally provides a way to sign in with a Google account, usable alongside a Microsoft account. The feature is rolling out to all Edge users on both Windows and macOS. System administrators, meanwhile, can control when it becomes available through the new NonMicrosoftAccountSignInEnabled policy.
In 2020, Microsoft stated it had no plans to integrate Google services into Edge by default. Edge is built on the Chromium engine, where Google engineers still make major decisions about the project, such as abandoning the Manifest V2 add-on standard. Despite being Chromium-derived, Microsoft has always used Edge to set its own technology agenda.
In June, Microsoft announced that Google account support was finally coming. Most likely, Edge users had been vocal enough to push the company into reversing its original decision. Official Google sign-in support could prove beneficial for users working across several Google services, potentially giving them a reason to stick with Edge even when they need browser-level access to Mountain View's platform.
After setting up a Google account, Edge users gain access to a few additional options, including faster sign-in on third-party websites and data synchronization across devices. Until Edge 150, Microsoft was effectively forcing Edge "enthusiasts" to rely on indirect workarounds to keep using their Google accounts in its native browser.
Beyond Google sign-in, the latest Edge release includes a few other changes worth noting. Edge 150 is the last version to support macOS 12 "Monterey." Edge 151 and all subsequent releases will require macOS 13 "Ventura" or later.
Edge 150 also migrates the Workspaces feature to a new architecture. The feature lets users create a "durable" set of tabs that can be saved for later use or shared with others; the V2 architecture removes the sharing function entirely, with Microsoft saying the change will improve the reliability and performance of tab sets.
