“Tanoe," the script that blocks macOS updates, is primarily intended for Macs not officially supported by Apple (often used with OpenCore Legacy Patcher/OCLP), as well as macOS virtual machines.
It also allows users to bypass the 90-day update window authorized by Apple via a configuration profile.
I sent it to many contacts, and several were shocked to discover it was a terminal script.
So, I created a Swift application with a graphical user interface (GUI), named "TanoeGUI," to simplify its use, especially for those unfamiliar with the command line.
