AirPort Utility not supported with MacOS Sierra V10.1.23
After I upgraded to Mac OS Sierra, my AirPort Utility is no longer working. I uninstalled and tried to re-install and get the following message:
"AirPort Utility can't be installed on this disk. The version of Mac OS X on this volume is not supported."
Please help me resolve this issue and I'll be honest, I do not know technical terms very well but appreciate any insight or advice. Thanks.
Mac mini (Late 2012), macOS Sierra (10.12.3)
