Requirements

Hardware

• Computer running the following operating systems.
  
  - MacOS 10.9 (Mavericks) to latest version. MacOS 10.9 is recommanded because most legacy jailbreaking tools can run properly on. Otherwise, MacOS 10.12 (Sierra) should would be the second choice.
  
  - Windows 7 to Windows 10 latest version
  
  - Linux (Debian based distributions are recommanded)

Software

Mac, Windows or Linux

  - On MacOS and Linux, ssh and scp are usually built-in in the OS. If you prefer a GUI tool, you can use PuTTY for interactive shell and FileZilla to replace SCP.
