+Subject: [PATCH] mac: handle Metal toolchain being unbundled from Xcode 26
+
+The Metal toolchain was formerly part of Xcode, but in Xcode 26, it has
+been unbundled and is now a separate install. Attempting to use the
+Metal toolchain without installing it results in a build error, such as:
+
+error: error: cannot execute tool 'metal' due to missing Metal
+Toolchain; use: xcodebuild -downloadComponent MetalToolchain
+
+By running the suggested command, the Metal toolchain can be installed,
+but the existing angle build does not know how to find it correctly.
+
+For system Xcode installations, tools from the Metal toolchain (`metal`
+and `metallib`) can be run via `xcrun`. This construct should work
+equally well for older Xcode versions, for situations where it’s still
+in use.
+
+For the hermetic toolchain, we’ll continue splicing the Metal toolchain
+into the location it had previously been avialable (see
+https://chromium-review.googlesource.com/c/6950738), although this is
+subject to change in the future.
+
+Bug: chromium:423933062, chromium:445400016

+Subject: Allow electron to depend on components/os_crypt/sync.
+
+This is necessary after
+https://chromium-review.googlesource.com/c/chromium/src/+/6944749
+landed.  That CL notes that "new code should use os_crypt async",
+so we can remove this patch once we migrate our code to use
+os_crypt async.

@@ -6,10 +6,10 @@ Subject: fix: disabling compositor recycling
 Compositor recycling is useful for Chrome because there can be many tabs and spinning up a compositor for each one would be costly. In practice, Chrome uses the parent compositor code path of browser_compositor_view_mac.mm; the NSView of each tab is detached when it's hidden and attached when it's shown. For Electron, there is no parent compositor, so we're forced into the "own compositor" code path, which seems to be non-optimal and pretty ruthless in terms of the release of resources. Electron has no real concept of multiple tabs per window, so it should be okay to disable this ruthless recycling altogether in Electron.

+Date: Wed, 24 Sep 2025 09:56:23 -0700
+Subject: Disable NSAutoFillHeuristicController on macOS 26
+
+The reason for this issue is that NSAutoFillHeuristicController is
+enabled by default on macOS 26. In pages with <input> tags, browser
+process sends synchronized IPC messages to renderer process. At this
+point, if the renderer process also sends synchronized IPC messages to
+the browser process, it will cause a deadlock.
+
+This bug can be reproduced on many websites. From the perspective of
+user experience, we should first disable this feature on macOS 26.
