I need to make my mac pingable (ICMP echo) on Mac OS Catalina. I understand I have to disable Stealth mode, but the option Stealth mode or Disable Firewall is still grayed out despite of clicking on yellow lock of the corner.
I can't find solution. Related help appreciated.
Thank you.
MacBook Pro Retina
Are you logged in with a standard user account or one with Administrator privileges?
Do you have 3rd party security app installed? Symantec...etc??
Good point. Of course I have administrator rights, but my MacBook is part of company BYOD. My employer deployed a profile, which disable handle with all security features.
Thank you. Problem was solved.
If you have Mac with T2 security chip, check here to see if you need to disable secure boot?/ https://support.apple.com/en-us/HT208330

No antivirus sw, native firewall only.
Option Disable firewall is still grayed out
