Hey @khahux

Look like your machine disables all Helper Tool service, so Proxyman helper tool could not install.

Ref: https://stackoverflow.com/a/32333522/3127477

Can you help me to print out the file /private/var/db/com.apple.xpc.launchd/disabled.plist

<key>com.proxyman.NSProxy.HelperTool</key>
    <true/>

Yay, it's disabled from your macOS.

Please try to delete this line. Restart the machine and try to install the Helper Tool again 🙌

很高兴知道它对您有用 🎉

oh my god!how fucking amazing it is! I cannot understand why but it works!and i do not find any others ways to work it.

[NghiaTranUIT]

Not sure why some OS blocks the Helper Tool by default, it will be fixed as soon as we unblock it 👍

To anyone, who has error CFErrorDomainLaunchd with code is 2. Here is the solution 👍

for whatever reason the helpertool plist in /Library/LaunchDaemons was owned by my user account, not root. 

No idea how that would have happened but more importantly switching the owner back to root and restarting allowed everything to load with the expected privileges so the update worked as expected once I opened proxyman
