Description

  • [ X] I am on the latest Hyper.app version
  • [ X] I have searched the issues of this repo and believe that this is not a duplicate
  • OS version and name: MacOS 26.0 (Tahoe) beta 3
  • Hyper.app version: 3.4.1
  • Link of a Gist with the contents of your hyper.json: standard .hyper.js, no changes
  • Relevant information from devtools (CMD+ALT+I on macOS, CTRL+SHIFT+I elsewhere): DevTools failed to load source map: Could not parse content for file:///Applications/Hyper.app/Contents/Resources/app.asar/utility.js.map: Unexpected end of JSON input
  • The issue is reproducible in vanilla Hyper.app: Is Vanilla

Issue

After update the MacOS to 26 (Tahoe) latest beta (beta 3), Hyper stopped to load the terminal. The window appears, but the cursor never show up. Other terminals like the Terminal.app (built-in) and Ghosty are working fine.

Research direction

Reproduce the issue with Hyper.app 3.4.1 on macOS 26.0 beta 3, using the vanilla configuration described in hyper.json and the DevTools error for utility.js.map as starting evidence. Investigate why the terminal window never shows its cursor; done means the terminal loads and accepts input on that macOS version.
