open.mp — Server Manager (macOS)

A native Swift / SwiftUI app for installing, configuring and running open.mp servers on macOS (Apple Silicon). It manages native macOS servers and Windows-32 servers via Wine — downloading and managing its own 32-bit capable Wine runtime, so no CrossOver is required.

Features

• Server — install official builds or import existing servers, then Start / Stop / Restart each one independently. Every server has live CPU/RAM stats, an inline colourised log, in-place engine updates (with one-click revert), and a lock indicator. macOS and Windows-32 (via Wine) servers are managed side by side.
• Setup — check the native macOS runtime and the Wine runtime; download or re-fetch the 32-bit Wine build used for Windows servers.
• Config — a modern config.json editor: name, passwords, port, max players, open.mp listing, single-select gamemode, and live filterscript / plugin toggles. Input guardrails throughout; keys it doesn't surface are preserved.
• Bans — view and remove entries from a server's bans.json.
• Snapshots — one log snapshot per server session, auto-saved on stop; view inline, export, or delete, filtered per server.
• Settings — Storage maintenance (clear Wine downloads, uninstall Wine, clear app cache, bulk-delete servers), privacy/telemetry toggle, update check, and about.

The whole UI shares one consistent layout: every tab has the same header, scope picker and footer-action bands.

How it works

Servers live in their own folders under ~/Documents/omp-server-manager/ (installed builds) or wherever you imported them from. Windows-32 servers run under a downloaded Wine build (wine32on64-capable) in a prefix under ~/Library/Application Support/Server Manager. Closing the window hides it; your servers keep running until you Quit.

Build

Requires Xcode 16+ / Swift 6 on macOS 14+.

swift build                 # debug build
scripts/build-app.sh        # release build + DMG -> dist/

Install

Download the latest DMG from Releases, open it, and drag the app to Applications. Launch it, then add a server from the Server tab (Install or Import).

The build is ad-hoc signed (not notarized): on first launch, right-click → Open (or System Settings → Privacy & Security → Open Anyway). Run it from Applications, not from the mounted DMG.

Telemetry

Optional, off by default. When enabled, anonymous usage is sent through a server-side proxy — the app ships no database credentials. No personal data, servers, or configs are ever sent.
