osu! captures my monitor/my second monitor is black


Behaviour

osu! has made all other windows inaccessible, and if a secondary monitor is connected, only your primary one is available.


Cause

When using the Mac driver with osu!, osu! will go into fullscreen mode and prevent other applications or system elements (like the volume control) from drawing on top of it. It’s great for performance, but can be annoying to play with osu! (especially since you won’t be able to drag and drop beatmaps into your Songs folder)

Resolution

These instructions are directly taken from Technocoder’s macOS troubleshooting guide.

  1. Click “Registry Editor” (Under the “Tools” tab in Wineskin in the left column)

  2. Go to this registry folder: HKEY_CURRENT_USER > Software > Wine > Mac Driver

  3. Double click on “CaptureDisplaysForFullscreen”

  4. Change “Y” to “n” in the text box

  5. Click “OK”

  6. Close the “Registry Editor” window


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.
