+Subject: build: restore macos deployment target to 12.0
+
+Partially reverts https://github.com/nodejs/node/commit/8b4022177750530d2c142a5a0349d98fb82f16e2
+Electron will follow Chromium's lead and deprecate macos 12 with
+M151, and so we should allow for building until then.
+
+This patch can be removed at the M151 branch point.
