I'm now on MacOS Ventura 13.1.
Recently, a pop-up window often appears on my pc.
"Background Items Added" "Steam" added items that can run in the background. You can manage this in Login Items Settings.
The first time when I saw this notification, I have turned off it in my "Login Items", and the second time I uninstalled my steam. But sometimes it still pops up. Then I have searched for completely remove steam from a mac. But it doesn't work, could you please help me with this problem? Thanks so much!
Remove the steam .plist file in ~/Library/LaunchAgents/.
