I am noticing some strange things going on with Hazel in the console. When I view the system.log I see the following output:

This happened right after I logged out and back in. I checked with launchctl and sure enough, HazelHelper is no longer loaded. When I try reloading HazelHelper with launchctl load ~/Library/LaunchAgents/*HazelHelper.plist it starts up and begins this failure cycle again.

Any help would be greatly appreciated!

Hazel v1.1.1

Well, I seem to have fixed my own problem. I still don't know why it was crashing, but after doing a complete uninstall (using the uninstall button in the pref panel) and then installing it again, the problem seems to have gone away. Perhaps it was an upgrade bug from pre 1.1?

Anyway, seems to be fixed.

Thanks.

I'm glad you were able to rectify it but I'm sorry you re-installed to do it. If it happens again, let me know as I haven't seen this before and would like to fix it. Also, if you get any log messages indicating why HazelHelper terminated, that would be great.

Thanks.

I'm having the same problem. It *might* have started after a log out / log in situation. I'm not sure. I noticed the rules stopped working about 2 days ago.

Here's a bit of the console log:

Same thing is now happening on my second computer at the office:

Yes, there's a problem right now with Hazel after logging out and logging in. After consulting with an Apple engineer, it appears to be a shortcoming in using launchd to do what I am using it for. If you want the semi-technical explanation: when you log out, the context launchd is in is deactivated so when you log back in, it's in a somewhat crippled state. As a result some operations will break.

I have written my own replacement for launchd (at least the parts that I used launchd for) for the next version and am shooting for a beta by the end of the month.

Until then, it appears a reboot is the only way to reset things. Also, if it's feasible in your situation, you can avoid the problem by not logging out and using fast user switching instead.

In any case, I hope you can hang on for a bit.

No problem. At least you know what it is.

At home it won't be that big of a deal, but at work, I log in and out every day.

Is there a way I could "unload" the helper with something like Lingon which would help the situation on the work computer?

Unfortunately, the user-level launchd is in this state permanently until the next reboot.

Another thing to try is just locking your screen at the end of the day (if you are the only one using the machine) or doing a restart instead of logging out. Not really ideal and I apologize for the inconvenience but this should be rectified soon.
