What's Wrong?

Bug Description

The Claude desktop app (Cowork mode) displays severe UI layout issues on Mac. Buttons are displaced/misaligned and half of the screen content is cut off, making the app unusable.

System Information

  • Device: MacBook Pro
  • OS: macOS [tu versión específica]
  • App: Claude for Desktop (Cowork mode)
  • Display: Built-in display (default resolution)

Steps to Reproduce

  1. Open Claude Desktop app
  2. Switch to Cowork mode
  3. Observe layout issues

Troubleshooting Already Attempted

  • Resized and maximized app window
  • Fully closed and restarted app multiple times
  • Deleted Claude cache folder at ~/Library/Application Support/Claude
  • Reinstalled the application
  • Reset app preferences via Terminal: defaults delete com.anthropic.claudefordesktop
  • Verified display resolution set to Default

Expected Behavior

App should display correctly with proper button alignment and full content visibility.

Actual Behavior

Severe text cutoff and misalignment issues where main content area has text partially cut off at edges.

What Should Happen?

The Claude desktop app (Cowork, code) should open with the correct layout — all buttons properly positioned, the sidebar and chat area fully visible, with no content cut off. The interface should be fully functional and usable.

Error Messages/Logs

No error messages appear. The issue is purely visual: the layout is broken on every launch. Buttons are displaced and part of the screen is cut off. No crash logs found.

Troubleshooting already completed:
- Deleted ~/Library/Application Support/Claude (cache, GPUCache, window-state.json, etc.)
- Reinstalled the app
- Ran: defaults delete com.anthropic.claudefordesktop
- Display resolution is set to Default
- MacBook Pro, macOS, built-in display

Steps to Reproduce

  1. Install the Claude desktop app (Cowork mode) on macOS
  2. Open the application
  3. The layout is immediately broken — buttons are displaced and part of the screen is cut off on every launch

Note: The issue is not related to any specific action within the app. It happens every time the app opens, from the very first moment.

TL;DR

The most likely fix for the layout issues in the Claude desktop app on Mac is to investigate and potentially update the app's UI rendering or layout management code to ensure compatibility with the macOS environment.

Guidance

  • Verify display settings: Ensure that the display resolution and scaling settings on the MacBook Pro are set to default or recommended values to rule out any display-related issues.
  • Check for updates: Although the user is on the latest version (1.2581.0), monitoring the app's update channel for any patches or fixes related to UI layout issues on macOS could provide a solution.
  • Investigate UI code: The development team should review the UI rendering and layout management code for any potential issues or incompatibilities with macOS, focusing on elements that could cause button displacement and content cutoff.
  • Test on different macOS versions: If possible, testing the app on different versions of macOS to see if the issue is specific to a particular version could help isolate the problem.

Example

No specific code example can be provided without access to the app's source code, but the development team could start by examining the UI layout code for any hardcoded values or assumptions about screen size and resolution.

Notes

The issue seems to be a regression, as it worked in a previous version, which suggests that a recent change might have introduced the problem. Without more specific information about the changes made between versions or access to the app's codebase, it's challenging to provide a precise fix.

Recommendation

Apply a workaround by potentially adjusting display settings or waiting for an update from the development team that addresses the UI layout issues on macOS. The reason is that the issue seems to be related to the app's compatibility with the macOS environment, and an update or patch from the developers is likely necessary to fully resolve the problem.
