How To Uninstall SystemLifeguard

1. The standard and easiest way to uninstall SystemLifeguard:

First, we need to make sure the app isn't running, so lets open Force Quit (from the Apple menu on the top left of your screen) and terminate the app if you see it running:


 - Now, open your Applications folder.
 - Right-click on "SystemLifeguard".
 - Click on "Move to Bin" (or "Move to Trash" on older versions of macOS)

2. How to remove SystemLifeguard using the Terminal:

 - Open the macOS Terminal from Applications > Utilities.
 - Type killall "System Lens", hit ENTER
 - Type rm -rf "/Applications/System Lens.app", then hit ENTER.
 - If that fails, try typing sudo rm -rf "/Applications/System Lens.app"
 - Now type rm -rf ~/Library/Caches/com.delveapps.systemlifeguard, hit ENTER.

This will remove SystemLifeguard from your Mac, but some supporting and related files will be left behind. Read on for how to remove those.
