Remove Startup Arduino CreateAgent on High Sierra

There are instructions on the GitHub page https://github.com/arduino/arduino-create-agent for both completely uninstalling the Arduino Create Multi Platform Agent and for disabling its automatic startup.

You have asked how to do the latter. In brief, from the Finder:

• Click on the Go menu, and select 'Go to the Folder'
• Type ~/Library/LaunchAgents and press Enter
• Select the ArduinoCreateAgent.plist file
• Right click on the file name and select 'Move to Trash'

Alternatively, using Terminal.app, issue the command

• launchctl unload ~/Library/LaunchAgents/ArduinoCreateAgent.plist

Using the second method of disabling automatic startup has two benefits: it retains the ability to easily re-enable it should you wish, while also allowing you the ability to start the process manually. To restore automatic startup, issue this command in Terminal:

• launchctl load ~/Library/LaunchAgents/ArduinoCreateAgent.plist

To launch the process on a manual "at-will" basis:

• launchctl start ~/Library/LaunchAgents/ArduinoCreateAgent

  [note that the .plist extension is omitted when using launchctl start]

The easy solution is if the application installed itself in system preferences. Select your user account and then review the startup items.

If it’s not there, you’ll need to look in the LaunchAgents and LaunchDaemons folders in your user library as well as possibly the /Library folder.

The go to short cut will help you go to ~/Library as well as /Library

• Accessing ~/Library in Open/Save dialogs
