Big Sur 11.2.1 (20D74) and active LuLu = everything is blocked

since the update Lulu 2.2.0 and 2.3.0 are blocking everything as long as its "enabled". outgoing internet connections, local Ssh, pings in the terminal, local smb shares. just everything. when I "disable" Lulu through the menu, everything is running smoothly instantly.

did apple change something essential?

Well I confirm like all the others that since Big Sur Lulu is blocking everything when activated

for me only with 11.2.1 update, before that its running flawless. and its totally random, on my MacBook with 11.2.1 its running fine

even more interesting: after reboot (Lulu started but disabled) everything is blocked. so I enable Lulu, still blocked. I disable it again by menu > everything is unblocked.

I get rid of the issue after uninstalling Lulu 2.2.O and then installing v 2.3.0. My config is Mac Mini M1 with Big Sur 11.2.1

Sorry about this! ...not sure if this is a LuLu or macOS/Apple bug (or combo there of)

Any additional info would be super helpful:

1. Can you confirm the extension has been approved? (System Prefs -> Security & Privacy)

2. Can you confirm the extension is running (System Prefs -> Networking)

3. What does systemextensionsctl list show?

systemextensionsctl list

enabled	active	teamID	bundleID (version)	name	[state]
*	*	VBG97UB4TA	com.objective-see.lulu.extension (2.3.0/2.3.0)	Extension	[activated enabled]

4. Can you run the following in the terminal, then toggle LuLu off/on ...and see if there are any error msgs/other log msgs of relevance? log stream --level debug --predicate="subsystem='com.objective-see.lulu'"

Thank you!!

uninstalled LuLu 2.2, installed LuLu 2.3 Mac OS 11.2.1 on a MBP 16" Network traffic is still superslow or not passing by as it should. Websites take ages to load, if they even do at all. Deactivating LuLu instantly fixes the problem.

while network related slowdowns remain the same

I can confirm that the issue exists with 11.1.0 and LuLu 2.3. I had the same issue with LuLu 2.0 and it was not finding new updates. So I updated manually. Furthermore, I can tell that the Tab in the network settings show LuLu as "Starting" and not "running"

exactly same problem here

Thanks for the feedback and additional information! ....seems that LuLu is perhaps stuck in the "started" phase vs. "running"

Will dig into why this is the case!

p.s. Is anybody who is having this issue not seeing LuLu in the starting phase? (can check via (System Prefs -> Networking)).

I got the same problem.

this happens in 11.3b2 so Apple must have done something recently as it worked in b1. I've just uninstalled for now.

It is happening for me in macOS 11.2.1 (20D74).

it fixed it for me, when I uninstalled LuLu by the context menu and reinstalled 2.3.0 afterwards

I can confirm that. Uninstalling and reinstalling it (with homebrew) solved the problems for me, too.

Thanks again for the feedback, if you can try the latest version, hopefully this addresses the issue(s)! 🤞🏼 LuLu v2.3.1: https://github.com/objective-see/LuLu/releases/tag/v2.3.1

Might be best to uninstall the/any previous version first? And running log stream --level debug --predicate="subsystem='com.objective-see.lulu'" from the terminal will output lots of helpful info, that can help me track down any (remaining) issues (Please share if you are still running into issues).

...also, may not work on the macOS 11.3 betas as Apple seems to be changing/breaking a bunch of stuff! 😅

Thanks again!

Unfortunately no changes under 2.3 > 2.3.1. MacOS 11.2.2, MBP 16" Activated debug with terminal. Hope that helps.

I am having this issue after upgrading to 11.3 (not beta). However, it appears to be a conflict with another network extension I use, TripMode. Either disabling LuLu or removing the TripMode extension allows apps to access the Internet.

I will contact the TripMode developer to see if they think it is an issue on their end, but I wanted to drop this here as an FYI.

seems to be fixed with 2.4.1., at least here everything seems to run finde. can anyoune confirm?

Just installed it yesterday on a new Mac and I don't have any issues. But I think at that time an update caused the issues and reinstalling could fix them.

This command really helped me. Perhaps it can be added to the FAQ page:

• log stream --level debug --predicate="subsystem='com.objective-see.lulu'"

along with this:

• confirm the extension is running System Prefs -> Networking

My problem is that I had 'Block Mode' on
