launchd

Something that I've noticed recently on two different machines is that Apache2 installed via MacPorts seems to have stopped launching when I boot up. The honest truth is that I can't swear it did so before, but it's something I think I'd notice because installing the LaunchDaemon is part of my install process. In fact, if I try to reload the LaunchDaemon, it fails: $ sudo launchctl load -w /Library/LaunchDaemons/org.macports.apache2.plist org.macports.apache2: Already loaded Unless I start Apache manually (using sudo apachectl restart ), grep'ing for either "apache2" or "httpd" in my process

I created a Command Line Tool app using Xcode. In that app, I used NSWorkspace to launch another application bundle (.app) as suggested here. MacOsX: How to launch an application (.app) from a "Command Line Tool" type of app All seem to work fine until I tried to start that Command Line Tool app as a daemon using launchctl. If the daemon is run as the currently logged in user, then the Command Line Tool app launches the external app just fine. If the daemon is run as root, then the Command Line Tool app cannot launch the external app. Using NSWorkspace to open an app doesn't seem to work if

I have an app that is crashing on the iPhone, but only when it launched via Xcode. I can see in the iPhone console log that the app receives a memory warning, and then there are some strange events like these: Sun Jul 11 00:03:43 Matts-iPhone com.apple.launchd[1] (UIKitApplication:com.mycom.myapp[0x3f60][5591]) <Notice>: (UIKitApplication:com.mycom.myapp[0x3f60]) Bug: launchd_core_logic.c:3270 (24132):0 Sun Jul 11 00:03:43 Matts-iPhone com.apple.debugserver-48[5590] <Warning>: 1 [15d6/1403]: error: ::read ( 6, 0x3809f4, 1024 ) => -1 err = Bad file descriptor (0x00000009) Sun Jul 11 00:03:43

I want to launch a specific app when a USB device is plugged in to a Mac OS X system. I've followed the recipe given in this SO post . But it appears the LaunchEvents key is not recognized: When I reboot my system, I see the following message on the console: com.apple.launchd.peruser.501[173] (com.example.program) Unknown key for dictionary: LaunchEvents I am running OS X 10.6.8, and it's entirely possible that xpc_events aren't supported in this version of OS X. If this is the case, what are my alternatives? (As a second, lesser question: is there a way to force a re-read of my .plist file

How would one set a minimum interval for a launchd.plist script with a WatchPath key? For example, I want to run a script every time new files appear in a directory, but I would like it to only run once an hour at maximum. The launchd.plist might look something like this: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>org.me.pytag</string> <key>ProgramArguments</key> <array> <string>/Users/me/bin/pytag.py</string> </array> <key>WatchPaths

Is it possible to know the .plist file location which is loaded into the launchctl command? The label name is listed with "launchctl list" and its contents can be viewed by "launchctl list LABEL", but I cannot find the .plist file location. I know it will be located in /Library/LaunchAgent or ~/Library/LaunchAgent or something, but I don't want to search around paths while all jobs is listed with the launchctl command. This issue comes up a lot and unfortunately locate and mdfind both don't show results from the appropriate directories on my system. I put the following function in my .bashrc
