I have a java application built with Eclipse, for Mac OS X.
This app is installed via a .pkg file and supposed to be daemonized. Everything works fine, with Macbooks (Pro, Retina), but with the iMac I work on, when the application launches, i have an icon on the Dock, as you can see on the
following link.
I have already tried the solution in this topic: stackoverflow.com/a/620950/3641679 but it didn't work (I still have the Dock icon). Currently the Info.plist looks like this.
What can I do?
Thank you for the time you'll be taking to help me.
Informations (assuming the app name is testapp)
- I stop or start the daemon using launchctl start/stop
- When I double click on the executable (in testapp.app/Contents/MacOs/testapp) i have the testapp.app in the Dock (with the icon file specified in the Info.plist). Here is a screenshot res.cloudinary.com/doit0eqlo/image/upload/v1400750376/app_k3adzh.png

Add this to your info.plist: -
<key>LSUIElement</key>
<true/>
Note that the value here is set to 'true' and not 1
As the Apple docs state: -
Specifies whether the app is an agent app, that is, an app that should not appear in the Dock or Force Quit window. See “LSUIElement” for details.
So, I finally found the solution! The solution is in several steps.
Step 1: Editing the Info.plist
I had to add the LSBackgroundOnly key. It is a string and has to be set to 1.
As said in the Apple Documentation :
LSBackgroundOnly
specifies whether this app runs only in the background. If this key exists and is set to “1”, Launch Services runs the app in the background only.
Information:
Although the documentation specifies this key is a boolean, setting it to a string with the value 1 in it does the trick.
To do so:
Go to your app's folder
Go into the .app's folder then the Contents one (eg. /Applications/test.app/Contents)
Open the Info.plist with any text editor you want (SublimeText, TextEdit,Xcode, etc.)
Add the following lines before the closing dict tag (</dict>)
<key>LSBackgroundOnly</key>
<string>1</string>
Save everything.
Step 2: Edit the appname.ini
Initially I only did the part 1, so it wasn't enough. I found the solution in this question.
The file is in the 'Contents/MacOs' folder inside your application's .app (e.g /Applications/testapp.app/Contents/MacOs/testapp.ini).
Open the .ini file (with any text editor you want).
Before the -vmargs line, add the following line: -nosplash
After the -vmargs line, add the following two lines:
-Xdock:hidden
-Dapple.awt.UIElement=false
Save the file, and now you can launch the app: it shouldn't be any icon neither in the Dock nor in the 'Force Quit' window, but your app should be running in the background.
Hope this helps,
