mosu - my osu or how to set up osu! for the best experience on Mac

My setup

• MacBook Pro 13" from 2018 in the base configuration
  • macOS Mojave (10.14)
• Apple Magic Keyboard
• One by Wacom (CTL-472)

Why not upgrade to the latest OS?

• macOS Catalina (10.15) has dropped the support for 32-bit applications meaning the osu! stable that is running on Wine is not working (at least there were no ports for Wine to 64-bit when I was trying it out)

Running the game

there are two official versions of the osu! game:

• osu! stable
  • this is the old osu! client that is still the main one (at the time of writing this)
  • emulated using Wine
• osu! lazer
  • completely rewritten in C# .NET Core to support all major platforms natively

Tweaks for the best performance (inspired by this and this)

• disable mouse acceleration (if you want to play with mouse)
  • Mouse Acceleration is an easy to use System Preferences plugin tool
• disable VSync (BeamSync)
  • when playing on dual monitors, the framerate is locked to 60FPS (the monitor's refresh rate)
  • disabling VSync always gives you less input lag
  • download Graphics Tools for your version of Xcode (will install many tool, all we need is Quatz Debug)
    • launch Quartz Debug
    • go to Window -> Quartz Debug Settings (or press command+1)
    • under Vertical Sync, uncheck Enable Vertical Sync
    • when you close the app (command+q or right-click the app in the dock and choose quit) the VSync will be re-enabled and so you have to open the app again and disable VSync when you want to play (unless you keep the app running all the time)
