Microsoft Edge Update Version 150.0.4078.48

Microsoft Edge 150.0.4078.48 includes feature updates for macOS support, Workspaces migration, sidebar retirement, and new enterprise policies. It also includes stable channel security updates and improved security validation for View in File Explorer.

• Updated View in File Explorer to enforce additional validation and restrictions when triggered by webpages to improve security.
• Security updates included in the Stable channel release.

• Users can sign in to Edge with a Google account in addition to a Microsoft account.
• Intune MAM protected downloads now save files to Documents > Microsoft Edge > Downloads in OneDrive.
• Enterprise-managed devices can use the DowngradeVersion policy to temporarily downgrade WebView2 applications to a previous Evergreen Runtime version.
• Microsoft Edge management service can now send security update alerts based on a chosen severity threshold.

• Microsoft Edge version 150 is the last release that supports macOS 12 (Monterey); version 151 or later requires macOS 13 (Ventura) or later.
• Workspaces are migrating from OneDrive/SharePoint to Edge Sync; collaboration/share functionality is being removed.
• Sidebar app list retirement means new apps can no longer be added, pinned apps will be removed in a future update, and sidebar app policies will no longer be supported.
• The NonMicrosoftAccountSignInEnabled policy controls availability of Google account sign-in.
• The DowngradeVersion policy applies only to enterprise-managed devices and uses msedgewebview2.admx.
