While in my shop and rebuilding components on Ella’s bike, I was disturbed by the fans on my Mac mini. Taking a closer look, I opened “top” from Terminal.app and found devicemgrd running away with one of the cores on the machine. Looking for a quick fix and reading Apple’s Discussions, it appeared a reset of the SMC was in order.

After pulling power, waiting about 10 seconds, pressing and holding the power button for 5 seconds, and then plugging the machine back in and pressing the power button again, it booted up and devicemgrd was behaving nicely again.

Back to bike repair.
