Early days, rough edges
Tiamat is an early test build, and we are sorry that it still shows. Expect bugs, missing pieces, the odd crash, and things that change from one version to the next. Thank you for playing this early and for bearing with us while it grows.
If something breaks, please tell us on GitHub.
Pick the right download
Open the Apple menu and choose About This Mac. If it lists a Chip such as Apple M1, M2, M3 or M4, take Apple silicon. If it lists an Intel Processor, take Intel Mac.
Open the download
Double-click the downloaded .tar.gz file. Finder unpacks it into a folder holding Tiamat.app and a folder named current.
Move the whole folder
Drag the whole folder into Applications or your home folder before you open the game. Keep Tiamat.app and current together. macOS runs apps straight from Downloads out of a read-only copy that cannot see the rest of the game.
Clear the quarantine flag, once
Open Terminal. Type cd and a space, drag the Tiamat folder onto the Terminal window, and press Return. Then run the line below. Without it macOS calls the app damaged. It is not: this test build is not signed yet.
Open Tiamat
Double-click Tiamat.app. Drag it to the Dock if you want to keep it there.
What you need
Your worlds, settings and identity are kept outside the game folder, so deleting the folder removes only the program.
