LULU firewall zombie?

[rjalex]

I am trying to help a friend that installed and uninstalled the Lulu firewall (I personally use Little Snitch and never used Lulu).

He cannot connect to Adobe Cloud and I am wondering if his uninstall could ever leave some "zombie" firewall rules.

Can anyone knwing Lulu tell me if this is possible?

I'd be inclined to help him reinstall, look at its interface to see if there are any rules, delete them and then uninstall it. Would this be the right way to go?

Thank you

Just like Little Snitch, LuLu relies on a Network Extension.
If you select “'Uninstall LuLu” from the status bar menu and reboot, the extension should be gone and all traffic permitted.
To check if the extension has been removed, from Terminal run:

systemextensionsctl list

If it returns
VBG97UB4TA com.objective-see.lulu.extension (2.5.1/2.5.1) Extension [activated enabled]
it is still active,
VBG97UB4TA com.objective-see.lulu.extension (2.5.1/2.5.1) Extension [terminated waiting to uninstall on reboot]
the extension will be uninstalled on reboot.

Check if Adobe connections are not blocked in /private/etc/hosts
From Terminal

cat /private/etc/hosts

should return only
127.0.0.1 localhost
255.255.255.255 broadcasthost

Sorry for the delay. Thanks a lot. Yes I have bought my Little Snitch license many years ago and never looked back

But LuLu is on a friend's Mac and I need to get rid of it!!! Will try your suggestions.

Take care.

PS It was even simpler as the /etc/hosts was the culprit.
