MapInstall
Garmin MapInstall is a macOS utility that sends compatible maps from your Mac to supported Garmin GPS devices and memory cards.
What is MapInstall?
Garmin MapInstall is a macOS application published by Garmin International for transferring compatible map data from a Mac to supported Garmin devices and SD cards. Garmin documents it as a separate Mac application and also states that installing Garmin BaseCamp on Mac installs MapInstall as well. The app is used after maps are installed on the computer, including maps made available through Garmin Express or other Garmin mapping workflows. It lets users choose a connected device or storage card and then send all compatible maps that fit or select smaller map segments for a partial installation. Garmin support materials also reference MapInstall alongside MapManager and BaseCamp in Mac mapping workflows, including installing, updating, converting, and removing Garmin map products. Mac users usually encounter it when managing map coverage for outdoor GPS units, automotive devices, or other compatible Garmin hardware.

Safety overview
Status: Safe
This is legitimate Garmin software used for map transfer to Garmin hardware. It is generally safe to keep when you use Garmin GPS devices or Garmin desktop mapping tools. Removing it does not create a broad system risk, but it can interrupt Garmin map installation and transfer workflows on the Mac.
Recommendation: Keep MapInstall if you use Garmin BaseCamp, Garmin Express map downloads, or a compatible Garmin GPS that needs maps loaded from your Mac. If you no longer use Garmin mapping tools or Garmin devices, it is optional and can be removed with related Garmin mapping components.
