Description

macOS version: 12.7.6 (Monterey)
OpenCode version: 1.3.0
Installation method: Homebrew / Official installer

Description:
When launching OpenCode Desktop, the window shows only the title bar - the rest of the UI is completely blank/white. The server starts successfully (I can see it listening on a port), but the WebView doesn't render any content.

I've tried:

  • Reinstalling OpenCode
  • Clearing cache (~/.cache/opencode)
  • Clearing app data (~/Library/Application Support/ai.opencode.desktop/)
  • Downgrading to 1.2.7
  • Disabling plugins

None of these worked.

My friend has the same OpenCode version (1.3.0) on macOS 13+ and it works fine. This appears to be a macOS 12.x WebKit compatibility issue.

The CLI and Web versions work normally.
