Behaviour

osu! crashes on startup, displaying an error message that says osu! was unable to obtain a graphics context.

Cause

This usually occurs because a user enabled Compatibility Mode in osu! settings, or changed to a screen resolution that Wine couldn’t handle.

Standard osu! uses OpenGL which is supported by the Wineskin, while Compatibility Mode will use ANGLE / OpenGL ES which is not supported by osu! Wineskins. This explains why osu! will crash with OpenGL ES-related errors on Compatibility Mode.

Resolution

1. Find your user profile/configuration file.

   • Locate where osu!.app (your Wineskin) is installed
   • Right click on it and select Show Package Contents
   • You should now see three files/folders: Contents, drive_c and Wineskin. Click drive_c.
   • From here, click osu!.
   • From here, locate osu!.yourcomputername.cfg and open this file in a plain text editor such as TextEdit.

For example, my configuration file is osu!.Adrian.cfg and it looks like this:

1. You’ll need to either delete or change a number of screen resolution options if you don’t know which is causing osu! to crash. If you know what option is breaking osu!, then you only need to modify/delete that specific option, as listed below.

Compatibility Mode

If you enabled Compatibility Mode and now osu! won’t start, find the CompatibilityContext option.

If you did enable it, it would look like this:

CompatibilityContext = 1

Change this to:

CompatibilityContext = 0

Then, start osu!

If you can’t find CompatibilityContext

Add the following line to the bottom of osu!.yourcomputername.cfg:

CompatibilityContext = 0

Then, start osu!

Screen Resolution

If you changed the screen resolution to something a bit weird, find these options:

• Height
• Width
• HeightFullscreen
• WidthFullscreen

Then, change the values accordingly to your last known previous settings, or to the recommended values as shown below. You can also delete them to have osu! initialise everything for you again.

Preferably:

• Height and Width should be Wine’s specified screen resolution (or otherwise, a standard screen resolution like 1920x1080)
• HeightFullscreen and WidthFullscreen should be your computer’s effective/scaled screen resolution.

Find Wine’s specified screen resolution

If you’re using Virtual Desktop on the X11 driver and need to modify Height and Width:

1. Locate where osu!.app (your Wineskin) is installed
2. Right click on it and select Show Package Contents
3. You should now see three files/folders: Contents, drive_c and Wineskin. Click Wineskin.
4. Click Set Screen Options
5. Locate the Screen Resolution dropdown as shown below — what it is set to is Wine’s specified screen resolution:

In this example it is 1920x1080. Therefore, Width = 1920 and Height = 1080.

Find your fullscreen resolution

• Width =
  
• Height =
  

Now, replace the corresponding Height and Width values in osu!.yourcomputername.cfg with those displayed above.

If that didn’t work

There could be something else going on here, and performing basic troubleshooting should help you get to the bottom of it.

If you’re not sure what’s going on here, copy any osu! crash logs as well as generating a report with osu!macOS Agent, and let us know on the forums.
