  1. Apple's official repair guides have made battery swapping on the M5 MacBook Pro marginally safer by recommending that the Battery Management System's cable should be removed first, precluding the risk of a short circuit even if the battery remains connected.
  2. Battery replacement in the M5 MacBook Pro is still a chore, requiring the swapping out of several internal components.
  3. The new MacBook Pro now has a 72.6Wh battery pack instead of the 72.4Wh one on the M4 MacBook Pro.
  4. Replacing most components still requires the removal of the logic board.
  5. Replacing the screen entails the removal of the antenna bracket first so as to access a number of tiny P2 screws.
  6. Access to battery pull tabs no longer requires the removal of the trackpad.
  7. Finally, the M5 MacBook Pro has secured a preliminary iFixit repairability score of 4 out of 10. For comparison, the M4 MacBook Air had secured a score of 5 out of 10.

Meanwhile, we reported recently that the M5 MacBook Pro's single fan and heatpipe setup failed to provide adequate cooling during the very intensive Cinebench 2024 benchmarking test.

Even so, the M5 MacBook Pro managed to outperform its predecessor by maintaining a core average temperature of 98.95 degrees Celsius vs. the M4 MacBook Pro's average core temperature of 100.90 degrees Celsius during the test.
