+Subject: fix: enable partition alloc ref count size for MacOS 13+
+
+Modifies an existing check to check for all versions of MacOS 13
+or higher, including MacOS 14 and potential beta versions.
+
+This patch is currently being added upstream, and can be removed
+when we integrate the upstream changes into Electron.
