My OS is masOS Tahoe 26.2, Tunnelblick version is 8.1beta03 (build 6340). When I open the APP, it will open the window and show "Tunnelblick need finish the update", after input the OS password, it will be tips:Need to replace and/or reload 'tunnelblickd'. the ~/Library/Application Support/Tunnelblick/TBLogs/tunnelblick-log.txt show:2026-01-28 01:22:54.966117: Need to replace and/or reload 'tunnelblickd':
tunnelblickdHashOK = YES
launchctlPlistHashOK = YES
tunnelblickdPlistOK = NO
socketExists = YES

I use many ideas and times to try deal with the problem by many kinds of AI's issues such as deepseek,doubao,qianwen and so on. But no idea can repair it, I try remove APP and download the lastest version to install it, but also have this problem.

Help me, thanks a lot.

After you provide the password so Tunnelblick can "finish the update" and Tunnelblick is running, please get the contents of

     /Library/Application Support/Tunnelblick/tunnelblick-installer-log.txt
and
     /Library/Application Support/Tunnelblick/tunnelblick-installer-log-old.txt

and post them here. (Note that the path starts with /Library, not ~/Library.)

Maybe it's closed by PrivilegedHelperTools. Because when I execute: ls -l /Library/PrivilegedHelperTools/net.tunnelblick.tunnelblick.tunnelblickd, it will be return: No such file or directory.
So, when I execute: sudo launchctl bootstrap system /Library/LaunchDaemons/net.tunnelblick.tunnelblick.tunnelblickd.plist, it will be return: Bootstrap failed: 5: Input/output error. So, tunnelblickdPlistOK = NO
Now, the problem is what should I do can make the Library/PrivilegedHelperTools/net.tunnelblick.tunnelblick.tunnelblickd is OK.

when I execute: ls -l /Library/PrivilegedHelperTools/net.tunnelblick.tunnelblick.tunnelblickd, it will be return: No such file or directory.

That's normal. Tunnelblick doesn't use /Library/PrivilegedHelperTools.

How did you originally install Tunnelblick? And what are the contents of the two installer log files I wrote about earlier?

I use the AppCleaner.app remove the Tunnelblick.app at first, then restart the macOS, then use the Tunnelblick_8.0_build_6300.dmg ,double click, put it in the application, then double click to install.

I've no idea to do sth for this problem now. I'm not sure it is the macOS26.2 's Compatibility issue or not. I need tunnelblick developer's help, thanks a lot.

Your AI is hallucinating: 
  • Never start a macOS application (a ".app") by running its binary. Start it by double-clicking on its .app, or by using the macOS "open" command.
  • Tunnelblick does not take a "--install-helper" argument.
Did you enable Tunnelblick's background programs, as recommended in Tunnelblick's Background Programs (which I linked to in my answer to you three days ago in GitHub Issue 877)?
