How can I change the desktop background image on macOS from a python script?
To change the desktop background image on macOS from a Python script, you can use the subprocess
module to run the osascript
command-line utility.
Here is an example of how you can do this:
import subprocess
# The path to the image file you want to set as the desktop background
image_path = '/path/to/image.jpg'
# Use the osascript utility to set the desktop background
subprocess.run(['osascript', '-e', f'tell application "Finder" to set desktop picture to POSIX file "{image_path}"'])
This script will change the desktop background to the image file specified by image_path
.
Note that you will need to have permission to write to the ~/Library/Application Support/Dock/desktoppicture.db
file, which is where macOS stores the current desktop background image. You may need to run the script with sudo
if you do not have permission to write to this file.
I hope this helps! Let me know if you have any questions or need further assistance.
Write a macOS service file which run when the network is up
On macOS, you can use launchd, a system-level process that manages other processes, to start a service when the network is up.
Here is an example of a launchd configuration file, also known as a "property list" or "plist," that can be used to start a service when the network is up:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.example.myservice</string>
<key>ProgramArguments</key>
<array>
<string>/path/to/service/executable</string>
</array>
<key>RunAtLoad</key>
<true/>
<key>WatchPaths</key>
<array>
<string>/Library/Preferences/SystemConfiguration</string>
</array>
</dict>
</plist>
This plist file includes the WatchPaths
key, which specifies that the service should be started when the specified paths change. In this case, the /Library/Preferences/SystemConfiguration
path is being watched, which is where macOS stores network configuration information.
To use this plist file, you will need to save it in the ~/Library/LaunchAgents
directory and give it a descriptive name, such as myservice.plist
. Then, you can use the launchctl
command to load and start the service, like this:
# Load the service
launchctl load ~/Library/LaunchAgents/myservice.plist
# Start the service
launchctl start com.example.myservice
# Stop the service
launchctl stop com.example.myservice
# Unload the service
launchctl unload ~/Library/LaunchAgents/myservice.plist
I hope this helps! Let me know if you have any questions or need further assistance.
