-Subject: [PATCH] bpo-44689: ctypes.util.find_library() now finds macOS 11+
- system libraries when built on older macOS systems (GH-27251) (GH-28053)
-
-Previously, when built on older macOS systems, `find_library` was not able to find macOS system libraries when running on Big Sur due to changes in how system libraries are stored.
-(cherry picked from commit 71853a73024a98aa38a3c0444fe364dbd9709134)
