My application is split into two parts. The main application and a helper tool. The helper tool performs a task with elevated permissions. The launchd plist looks like this: (Only important settings included.) <key>UserName</key> <string>root</string> <key>ProgramArguments</key> <array> <string>/Library/PrivilegedHelperTools/helper...
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...
I'm using mac osx 10.6 - and it seems that the minutes parameter determines how many minutes past the hour that the job runs. But how do you set up a job to run ever x minutes past the hour. I've tried setting up minutes as an array of several numbers and an array with one string which is "*/5" i.e. similar to every five minutes syntax...
The Mac OS X system startup program launchd enables job scheduling (similar to cron.) By creating a launchd agent, one can trigger programs through one of the following events: an interval of time has elapsed a certain calendar date has come a file path has been modified something has been placed in a certain directory (queue directory...
I've written a launchd .plist which should attach a debugger to the WindowServer when it launches. The main part of the script looks like screen -D -m -S "WindowServer Debugger" \ gdb \ -x $GDBSCRIPT \ /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreGraphics.framework/Versions/A/Resources/WindowServer ...
I'm attempting to write a launchd agent that runs a simple application for every user that logs in to the Mac OS X system. I have created a file named com.mycompany.myapp.plist and placed it in /Library/LaunchAgents. The contents of that file are: { LimitLoadToSessionType = "Aqua"; StartInterval = 10; OnDemand = NO; Kee...
I have a launch daemon that runs in the login context of a Mac OSX 10.6 machine. I want to launch an agent for each user from that agent, and have the agent run in the user's login context. However, I need to control the precise arguments to the agent application very carefully, which is why I cannot use a launchd agent, like I have for ...
I'm a Linux user that just recently got a mac. I'm trying to set up my IDE and found out that Macs don't use .bashrc / .bash_profile / etc. for GUI apps. So, if you have a GUI app that needs an environment variable, you're apparently supposed to do it in /etc/launchd.conf The thing is, this file uses csh style setenv syntax ("setenv key...
I have some launchd plists that are now placed at the administrator per-user level, particularly inside: - /Library/LaunchAgents OR - /Library/LaunchDaemons I'd like to avoid that some of those services could start only for one user (possibly avoiding to move all the plists to ~/Library/LaunchAgents), which is the simplest way? Thanks ...
Is there a way to get the standard error/output path from within the process? I tried NSTask's standardError but it returns NSFileHandle, and I need the path as string. Thank you! p.s. StandardErrorPath is set in a .plist used by launchd to start the process on system start. The process is a bundle, written in objective c. ...
Hi all, I find there is no daytime server available in leopard/snow leopard. And after reading some documents, the approach I can think of is writing a daemon and put it under /System/Library/LaunchDaemons, so that launchd can run it. I wonder if there is a way to just enable the service rather than writing a new one myself? Thanks in...
I have a small Foundation application that checks a website and plays a sound if it sees a certain value. This application successfully plays a sound when I run it as my user from the Terminal. I've configured this app to run as a LaunchDaemon, with the following plist: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//...
I am writing driver to a HID device. The driver opens HID device in exclusive access mode. This driver should run for all user. So it should be either User agent or daemon. In driver I use some CoreGraphics API's which is under ApplicationService framework but Technote say's daemon won't get access to ApplicationService framework. So...
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>: (UIKitApplicat...
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 "...
I'm working with launchd to run some automated tasks, and I was wondering what the difference is between 'Day' and 'Weekday'. According to http://discussions.apple.com/thread.jspa?threadID=1361809 there is a 'subtle' difference that can cause launchd to misbehave. Ultimately, I'd like to have a plist that runs every weekday (Mon - Fri...
I think launchd is the answer, but using this plist: http://gist.github.com/553573 I get this error: Exception in thread "main" java.lang.NoClassDefFoundError: net/appjet/oui/main Caused by: java.lang.ClassNotFoundException: net.appjet.oui.main at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessCo...
I have a mac mini os x 10.6.4 which I use to host a web app for private use only. For certain functionality I needed a cron job so i used lingon (http://lingon.sourceforge.net/) to setup a launchd cron job - this creates a plist file in the following folder /library/launchDeamons folder. the job it self is just "curl -s localhost/api?met...
On an OS X 10.6 system I am trying to use StartCalendarInterval in launchd to replicate a cron job that runs on the 5 minute marks of the hour. (It is important in my application to start when requested and not merely start again five minutes after the previous invocation.) I find that the actual start time of the job varies considerably...
Hi Everyone I have created a plist file to launch my app (10.5 & 10.6)on the login screen, die when logging in and the respawn when the Desktop is loaded. If i place my plist file within /Library/LaunchAgents it runs correctly. If i try running it from /Library/LaunchDaemons it does not run. As this is my first app for the Mac i am uns...
