Hello guys. Hope you are doing good. My 2017 iMac got abruptly shut down because of a power outage which was caused by an external device -> the electrical system in my house gets overloaded when the lawn mower is plugged in and too many other devices are running like lights and iMac. Someone plugged in the lawn mower and caused a power outage. Second time in 3 weeks. Enough rambling: This sure can't be healthy for the macOS or the interal disk. How can I check if there are any problems with my iMac after the power outage? Disk health or similar things. I checked the activity monitor and after the first two uses there were CPU tasks called "mdworker" (a dozen of this one), "mds" and a 3rd one that I can't remember. They used tons of CPU - up to 89% - and this went on for almost ten minutes. Spotlight seemed to use a giant amount of CPU % as well. Hope someone can help me here.
