Unmount volumes with macOS installed

README.md

Unmount volumes that contain a macOS installation

For testint purposes I have a few partitions with a clean install of macOS, these partitions contain applications I use daily. Somtimes spotlight starts applications from that volume.. that is just super annoying I use this script to unmount them after start up.

Installation

You just have to move these files

mv nl.mauriciokruijer.unmountvolumes.plist ~/Library/LaunchDeamons/
sudo mv unmountVolumes.sh /usr/local/bin/

nl.mauriciokruijer.unmountvolumes.plist

volumes=("Rescue" "10.12 Omni test" "10.13 Omni test" "Base 10.12" "Base 10.13")
for i in "${volumes[@]}" ; do
  volume="/Volumes/$i"
  if [ -d "${volume}" ]
    then hdiutil unmount "${volume}" -force
