Disabling Adobe CC Client Startup on macOS
The Adobe Creative Cloud client on macOS by default always starts up at login. Software that automatically injects itself into your starup items is bad enough, but worse yet you can't control it from System Preferences --> Users & Groups --> Login Items. Here's how to disable it from the terminal:
launchctl unload -w /Library/LaunchAgents/com.adobe.AdobeCreativeCloud.plist
Re-enabling it as just as simple:
launchctl load -w /Library/LaunchAgents/com.adobe.AdobeCreativeCloud.plist
