Problem
Switching display modes in macOS is fine if you do it once a month. It is annoying if you do it several times a day.

ResoSwitch.
A quick-access resolution switcher for macOS.
Useful when you switch between a laptop screen, an external monitor, screen sharing, and recording setups often enough for System Settings to get old.
Approach
Keep it native, keep it small, and put the common resolutions in the menu bar where they are one click away.
State
It has a public release, installers, favorites, shortcuts, and the usual unsigned Mac-app caveat for now.
Why I made it
A tiny annoyance, repeated often enough.
I switch between display modes more often than macOS seems to expect. More space while working, larger UI for screen sharing, different settings when an external monitor is attached.
ResoSwitch is the boring fix: click the menu bar icon, pick the mode, move on. Favorites keep the common choices at the top, and shortcuts cover the ones I use all the time.
It is also honest about where it is. The app works, the release artifacts exist, and the Mac packaging still needs the proper signing and notarization pass.
What is in it
Objective-C and AppKit, because this kind of utility should feel like macOS.
CoreGraphics for reading and applying display modes.
Favorites per display, including HiDPI and external monitor modes.
Cmd+1 through Cmd+9 shortcuts for the modes I use most.
PKG and DMG builds are available; signing and notarization still need finishing.
Next step
Go back to Projects for the wider list, including Passary and TipSignal.
Open the latest GitHub release if you want the installer. It is still unsigned, so macOS may need the usual right-click Open treatment.
