I finally figured out why my MBP has been soooo slow! Turns out that a left over program from my PBG4/Tiger migration had some dumb daemon running from a program called HamachiX.

HamachiX is an excellent program, but now that Leopard has “Back to my Mac” and I have a .Mac account, HamachiX hasn’t been used in months.

So in my Console log files it looked like this:

1/29/08 11:39:54 PM tuncfgd[6864] tuncfg: already running, use ‘killall tuncfg; tuncfg’ to restart it
1/29/08 11:39:54 PM com.apple.launchd[1] (tuncfgd[6864]) Exited with exit code: 1
1/29/08 11:39:54 PM com.apple.launchd[1] (tuncfgd) Throttling respawn: Will start in 10 seconds
1/29/08 11:40:04 PM tuncfgd[6865] tuncfg: already running, use ‘killall tuncfg; tuncfg’ to restart it
1/29/08 11:40:04 PM com.apple.launchd[1] (tuncfgd[6865]) Exited with exit code: 1
1/29/08 11:40:04 PM com.apple.launchd[1] (tuncfgd) Throttling respawn: Will start in 10 seconds

So here is the solution:

Open HamachiX

Go into Help, System Support, Uninstall System Components

Now you can uninstall Hamachi if you want, if not, you’ll have to install every time you want to use it. Editing the tuncfgd.plist (from Apple Help forums) didn’t work even after rebooting and restarting launchd.

Hope this helps!
