Install Gritpack
One download on a Mac, or one command in a terminal. Either way Gritpack keeps itself up to date afterwards.
Mac
For Macs with Apple silicon. Open the download, double-click Install Gritpack, and confirm.
The download is not yet signed with an Apple Developer ID, so the first time macOS says it cannot check it. Open System Settings → Privacy & Security, choose Open Anyway beside Install Gritpack, then open it again.
Linux, or a Mac terminal
For Linux on x86-64 and Macs with Apple silicon. It downloads the Gritpack installer, checks it against the checksum the hub pins, and asks before installing.
