UO Outlands on Mac (Apple Silicon) - Installation Guide

A guide to running UO Outlands natively on Apple Silicon Macs (M1/M2/M3/M4) using Wine.

Credit: Based on Vercillo's method from the UO Outlands Discord (#unofficial-mac-linux-support channel).

Prerequisites

Required for running Intel-based components:

softwareupdate --install-rosetta

brew install --cask wine-stable
brew install --cask --no-quarantine Sikarugir-App/sikarugir/sikarugir

Open Sikarugir Creator (from Applications)
Select Engine: Choose WS12WineSikarugir10.0_1 (or latest available)
Create Wrapper: Click "Create" and save as Outlands.app in ~/Applications/Sikarugir

Open your new Outlands.app - it will show the Configure window
Enable D3DMetal: Check "Direct3D to Metal translation layer (D3DMetal)" ⚠️ Critical - the game will crash without this
Install .NET: Click "Winetricks" → install all "MS .NET Runtime" options
Install Outlands: Click "Install Software" → select the Outlands installer
Set Launch Target: After installation, click "Browse" next to "Windows app" and navigate to outlands.exe (typically in C:\Program Files\Outlands\ or C:\Outlands\)

Double-click Outlands.app in ~/Applications/Sikarugir

Important: Make sure the wrapper points to outlands.exe (the launcher), not classicuo.exe directly - this ensures you receive game updates.

Issue	Solution
Audio static/popping	Open macOS Audio MIDI Setup → change sample rate to 96KHz
Keyboard not working	Check keyboard mapping in wrapper config (Options tab)
Need to access config files/scripts	Right-click wrapper → "Show Package Contents" → navigate to find Razor profiles, gumps, etc.
Need to reconfigure wrapper	Right-click wrapper → "Show Package Contents" → `Contents/Configure.app`

Razor scripts work well - users report running complex boss scripts without issues
Performance is generally good on Apple Silicon
The wrapper is ~5GB after full installation

Tested on M4 Pro MacBook Pro running macOS Tahoe (26.2).
