com.apple.CoreSimulator.CoreSimulatorService - Crash (18 times)

My 2020 iMac is behaving very unstable with a lot of stalls, beachballs, slowdowns, crashes and random reboots.


Running EtreCheck and looking at Console running I'm noticing a lot of CoreSimulatorService activity going on.


Any help would be most welcome.


EtreCheck reports the following...


   2020-11-01 11:41:32 com.apple.CoreSimulator.CoreSimulatorService - Crash (18 times)

And here is a snippet from the Console...

Thank you Lucas, this helps me. I entered the commands manualy.


killall Xcode
sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

Found no matching processes.


And

rm -rf ~/Library/Developer/CoreSimulator/Devices

did not work, got a "Directory not empty" message.


But I changed to this directory and deleted the files again.

After that my CPU fan became quiet again and the ReportCrash process disappeared.


To be on the safe side I started Xcode and had the missing packages installed.

I had the same problem on big sur after updating. It would crash constantly.


The issue is likely that your simulator config files are corrupted.


I solved it by running this shell script I found in a github repo.


#!/bin/bash

# Kill any running Xcode or CoreSimulator processes

killall Xcode

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

# Remove existing simulators, including any installed apps

rm -rf ~/Library/Developer/CoreSimulator/Devices


# Recreate available devices and simulators to correspond to iOS runtime bundled with installed Xcode version and any additionally-installed runtimes

open /Applications/Xcode.app

# List available devices (in /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/CoreSimulator/Profiles

# and /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Developer/Library/CoreSimulator/Profiles),

# simulators (in ~/Library/Developer/CoreSimulator/Devices/)

# and runtimes (in /Library/Developer/CoreSimulator/Profiles/Runtimes/)

xcrun simctl list
