Mac OS. I am unable to expand zip file. I have tried this: Unzip in Terminal:

  1. Open the terminal
  2. Type unzip and a space, then drag/drop the zip file into the Terminal window.
  3. Press Enter and the zip file will be unzipped, storing all files on your computer.

When i try to open the zip file it reads

unable to expand (error 1- operation not permitted).

Online p7zip seems to be recommended Here's the instructions

You can install it via MacPorts or Homebrew with these commands, respectively:

sudo port install p7zip
brew install p7zip

Then, to unzip it, use: 

7za x file.zip

Please explain the steps to enter this code, i don’t know what it means. But i'm happy to learn something new

The mac archive utility doesn't permit you to unzip large files using the command line

unzip file.zip
