The wifi has an exclamation mark. Can't use wifi. Not able to turn on. Throwing preferences error whenever I try to open Network from System Preferences. Also not able to find SystemConfiguration under Library/Preferences/SystemConfiguration. Not able to run diagnostics as well.
I have tried to remove the DNS cache. Restarted system quite a few time, etc. nothing is working for me.
Please help.
So, what App was installed ?
CleanMyMac per chance ?
If so, follow below. Understand - depending on the amount of damage it has caused, it might require a Reinstallation to to put the OS right again.
Strongly suggest remove it as per Developers Instructions. Do not install and Uninstaller as they too tend to create havoc and moved important elements of the OS.
As a Testament of how much Damage this application can cause - the first 600 Posting on the ASC Forums all point to the same conclusion - https://discussions.apple.com/search?q=cleanmymac

Any Third Party Applications that will interfere with the normal operation of the OS, alter, modify, remove or delete or attempt to do so is an invitation for disaster and may require a Reinstallation of the OS.
This includes AntiVirus, Disk Cleaners, Disk Optimizes, UnInstaller etc.
I assume you're using OS Monterey, if so go here https://support.apple.com/guide/mac-help/wi-fi-network-preferences-mac-mchlp1181/12.0/mac/12.0 if not you can still use the link just enter your OS in the field above. (in the linked page)
Cheers, Deezee
does this happen if you boot to Safe Mode?
I did install one app recently, it may have contributed to this issue. Cause this happened a few days after installing that app.
Yes, I have installed Whatsapp app. Thanks for providing me with this information. I will be uninstalling this app and re-install my MacOS.
Thanks a lot. :)
Welcome and thank you too.
