This higher-chip 14-inch chassis uses stretch-release battery adhesive partly hidden under the trackpad; USB-C and MagSafe are separate jobs.
What to check before buying
Battery
iFixit notes that not every stretch-release strip is directly accessible. The trackpad must be removed to reach hidden strips.
Ports and cooling
USB-C ports, MagSafe connector, dual fans and heat sink have distinct guides. These Pro/Max components should not be inferred from the base M4 model.
