Mac will restart on its own. Sometimes properly, other time with half blue screen during apple logo and screen turns off/black. In safe mode also same but it restarts properly. screen will be like blue contrast but then returns to original. Also recently i had switched from hdd to ssd (don't think its because of this) IMac details - 4k 21.5inch 2017 3GHz Intel Core i5 Radeon pro 555 2GB 8GB 2400MHz . Please someone help me figure whats wrong. Did all the resets. System hardware diagnoses shows no faults.

"com.apple.xpc.launchd" refers to launch daemon for for the "xpc" service. The service exited (completed) as the result of being sent an exit signal - "SIGKILL" - which came from "mds." The latter is the main Spotlight engine.

As with all messages in Console, it doesn't mean anything except to the developer (Apple, in this case).
