Comparison

Mac Nudge is for approvals. Screen sharing is for full control.

If your Mac only needs one visible button click while you are away, a full remote desktop session can be heavier than the problem. If you need passwords, settings, or a complex workflow, use direct remote access.

Tool Best for Tradeoff
Mac Nudge Approving standard macOS alert dialogs from iPhone without opening a full remote desktop session. Not for passwords, Keychain, System Settings, or complex windows.
Screen Sharing or VNC Seeing and controlling the whole Mac when you need context or multiple steps. Heavier than a simple approval and often awkward from a phone.
TeamViewer or AnyDesk Cross-network remote support and full interactive sessions. Useful, but more broad than approving a single dialog.
Apple Remote Desktop Managed Mac fleets and administrative remote control. More infrastructure than most creator, developer, office, or single-Mac workflows need.
