Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area : apps/desktop
Impact: Minor bug or occasional failure
Version or commit: All Versions
Environment : macOS 26.2, Homebrew 5.1.1, zsh 5.9 (arm-apple-darwin25.0.0)

Steps to reproduce

---

Setup:

This issue happens when you are:

• On the desktop version of T3Code on MacOS running zshrc shell
• Have HomeBrew setup
• Have zshrc plugins setup via homebrew
• or have $HOMEBREW_PREFIX referenced as path in your ~/.zhsrc

Steps:

1. Start the desktop app with the latest version (0.0.14)
2. Open any old or new thread and then open the terminal
3. Terminal opens and works but you see the following error message

Reason for the issue:

---

From the code in readEnvironmentFromLoginShell & readPathFromLoginShell we are calling the shell to fetch variables but copying only PATH and in some places SSH_AUTH_SOCK . Homebrew variables are not included.

NOTE: Though adding Homebrew to the list might fix this related issue but other variables that might be defined in ~/.zprofile might get missed.

Add HOMEBREW_PREFIX to the allow list in readEnvironmentFromLoginShell
