Download & start playing

Open the DMG, drag “OldEraMT2” into “Applications” and start it. On the first start OldEraMT2 downloads the client (about 1.2 GB) and sets up the game environment (about 1 minute).

On the first start macOS says the app could not be verified. Close the message, then: System Settings > Privacy & Security > at the very bottom, next to “OldEraMT2 was blocked”, click “Open Anyway” and confirm with your password or Touch ID. This is needed only once.

On Macs with Apple silicon, yes: macOS offers it on the first start (“Install”). Intel Macs with macOS 13 or later do not need it.

Extract the archive, then start “OldEraMT2.sh” (double-click or ./OldEraMT2.sh in a terminal). On the first start the updater downloads the client (about 1.2 GB) and sets up Wine (about 1 minute). Afterwards “OldEraMT2” appears in your application menu.

An x86_64 computer with glibc 2.27 or newer and OpenGL (Mesa or NVIDIA). “zenity” helps for the progress window but is not required.

Linux: ./OldEraMT2.sh --reset rebuilds the Wine environment, the client files are kept. If the package does not start at all, the multilib package helps (see below). On the Mac the game always runs with OpenGL. If nothing helps, attach the logs in Discord support.

A fallback for systems where the normal Linux package does not start. It uses the 32-bit libraries of your system (i386/multilib, e.g. 32-bit Mesa/OpenGL) – they must be installed. Data, updates and usage are the same.

macOS: ~/Library/Application Support/OldEraMT2 · Linux: ~/.local/share/OldEraMT2. It contains the client, the game environment and the logs folder.

Automatically: on every start OldEraMT2 checks the signed update channel and downloads only changed files – just like the Windows patcher. When a new version of the Mac or Linux package is available, OldEraMT2 asks. On the Mac, then drag the new app into “Applications” and choose “Replace”; on Linux OldEraMT2 swaps the package itself (manually: --update-package, back: --rollback-package).
