M4 MacBook Pro Teardown Reveals Limited Internal Changes

Apple's latest MacBook Pro features a slightly larger heatsink and improved port replaceability but retains repairability challenges.

The M4 MacBook Pro introduces a larger heatsink to support the new M4 Pro chip's thermal demands, with minimal internal design changes otherwise.
An additional USB-C port is included on the base M4 MacBook Pro, marking one of the few external updates to the device.
While some ports are now individually replaceable, key components like the MagSafe port and card reader remain soldered to the logic board, complicating repairs.
Battery replacements continue to be hindered by stretch-release adhesive, with no adoption of the simpler battery removal method seen in recent iPhones.
Apple will soon offer standalone speaker parts for repair, a cost-saving improvement compared to previous top-case replacements.
