LoadMyTracks (on the Mac AppStore and for direct download) is compatible with macOS 12 (Monterey) beginning with version 1.5.5 (112). If you have any trouble with LoadMyTracks on Monterey, please make sure you're running the latest versions of the OS and LoadMyTracks before reporting a bug.
Note that these releases are also Apple Silicon-native and should work natively on any Mac running 10.13.5 or greater.
