Note: The three versions of Office20 16 tested by this method are V 15. 16, V 15. 17 and V 15. 18 respectively. Use may be risky and users need to pay attention. Read the running code carefully before running. Make sure that all five applications of Office20 16 on the Mac are the same version.
Open the terminal (launchpad-other-terminal), copy the command starting with sudo to the terminal (copy the command to ""here ""sudobash-c "curl-s/best/officethinner wxhlbl.com/master/OfficeThinner.sh | bash" "), and enter your Mac password (usually your boot password). Of course, after every update of Office20 16 on Mac, the occupied size of Office20 16 will be restored, so if you want to slim down Office20 16 after every update, you need to run this terminal command once.
