ResolutionChanger
ResolutionChanger is a macOS menu bar utility for quickly switching display resolutions without opening System Settings.
What is ResolutionChanger?
ResolutionChanger is a native macOS utility that helps users change display resolution directly from the menu bar. It is designed for people who frequently switch screen settings, such as users moving between external displays, testing layouts, or adjusting workspace visibility. The app provides quick access to available resolutions so you can make changes without navigating through System Settings each time. It also supports favorites for commonly used resolutions, making repeated switches faster in daily use. A current-resolution readout in the menu bar helps you confirm settings at a glance, and launch-at-login support keeps the tool ready after sign-in. ResolutionChanger is published by Cassaicus and distributed for Mac through the App Store.

Safety overview
Status: Mostly safe
This app changes display settings, so temporary screen flicker or brief display reconfiguration is normal while switching resolutions. That behavior is consistent with its purpose as a display utility. It does not list data collection on its App Store privacy label, but you should still install it from trusted sources and use only the display changes you expect.
Recommendation: Keep ResolutionChanger if you regularly switch monitor settings or want faster access from the menu bar. If you do not use it, you can remove it without affecting macOS beyond losing its quick resolution-switching convenience.
