Store description excerpt
Default App Mapper puts every file type association on your Mac into one screen, and lets you change any of them in two clicks. macOS keeps this setting inside the Get Info panel, one file at a time. No screen tells you what opens your .csv files, or which extensions the editor you installed last week quietly took over. Defaults drift, and you find out only when the wrong app opens. Open the app and every extension is listed next to the application that currently opens it, sorted into Documents, Images, Video, Audio, Code, Archives, Data and Other. Click an app name and pick another - only applications that can actually open that type are offered, and the change applies system-wide right away. Switch to Group by App for the opposite view: exactly which extensions each application has claimed, so you can hand back the ones you never meant to give it. Search filters by extension or app name. Around 285 common extensions are covered. One screen for every file type default on your Mac. Native SwiftUI for macOS Sonoma and later, with no account, no server and no network connection - everything stays on your Mac.
