Unusual high CPU load on older Macbooks with removable battery

  • Live Versions: ALL
  • Operating System: OSX


Live shows an unusual high CPU load on older Apple Macbooks or Macbook Pros with removable batteries, if the Macbook is used while the battery is removed and only being powered by the power adaptor.


This is a known problem as those Macbooks and Macbook Pros automatically reduce the processor speed as those machines demand more power than the power adaptor alone can deliver.


Macbooks with removable battery should not be used while only being powered by the power adaptor in order to avoid performance issues.
