How to delete things from /usr/bin

gistfile1.sh

# In macOS Catalina onwards `/usr/bin` is protected. Before you would only need to run a root shell to make any changes. Now there is something extra to do.

# Let's say I want to run this command:
# sudo rm -rf /usr/bin/python3

# Deleting something will give you the error:
# rm: /usr/bin/python3: Read-only file system

# To get around this you need to first run:

sudo mount -uw /

# Then the above command will work as expected.

sudo rm -rf /usr/bin/python3
