App Update Helper Password
Mac OS Big Sur has prompts for password every now and then and turns out all you need to do is give access to admin: read/write. Sometimes it's not present in the Get Info window and only everyone, user is present and system.
chown is a command to used to change ownership. To change ownership of Slack.app, you'd want to run something like:
sudo chown -R $USER:staff /Applications/Slack.app
in a Terminal window. $USER should get replaced by your username automatically, but if it doesn't, just replace it with your computers username.
You can see who the current owner is by running
ls -la /Applications/Slack.app
If you see root in there, you probably need to run the command above.
Mind Map
Change ownership of bash scripts in linux, so it applies here in macOS as its kernel is based on unix subsystem AFAIK.
