MacBook without battery kernel_task 100% CPU utilization After removing the battery from a MacBook late 2009 following a battery fault, the computer always runs kernel_task at 100% CPU utilization. I assume the process ends up in some kind of spin lock when looking for the battery and failing to do so. Is there a work around to prevent this issue? While waiting for a new battery, I would like to use the computer in a useful way on connected power.
The procedure mentioned here, involving the removal of one specific system file, will probably disable the sensor check and prevent the kernel task from gobbling up your CPU, while waiting for your battery: https://apple.stackexchange.com/a/146381/226332
