MacOS – What change does the OS need to make, given this message? “iCloud Preferences wants to make changes to your account”
macosSecuritysystem-prefs
This message appears when I log on to my machine. It doesn't tell me what change it wants to make, so I deny it access to my system.
Does anyone know what change it is trying to make?

It's trying to set up the iCloud account as a trusted authentication platform for your local user account. This is usually for a feature such as the Apple Watch unlock, whereby the Apple Watch can unlock your local account through iCloud.
You can use sudo opensnoop -n ProcessName to see what files have been opened by a process, but only after they've been accessed of course. You could also use fseventer to display modified files in a tree view.
The dialogs are shown by installers because they need root permissions to modify /Applications/ or other folders that aren't owned by the user. You can press ⌘I to see what files would be copied by an installer.
If my Googling-fu is stronger than yours, this appears to be linked to the Viscosity VPN client.
According to Viscosity technical support, Viscosity stores registration and trial information in this file, however it can be safely deleted if needed.
