MathJax is not rendering ChatGPT responses correctly on macOS application (on Safari it works fine)
• Example:
MathJax \underbrace{…}_{…} expressions fail to render correctly in the macOS ChatGPT app.
• Steps to Reproduce:
- Open ChatGPT app on macOS.
- Let chatgpt echo message:
\[
\underbrace{a + \dots + a}_{n\text{ times}}
\]
- Send and view response.
• Expected Result:
The underbrace appears beneath the summed terms, with the label “n times.”
• Actual Result:
The underbrace label renders as plain text; the brace graphic is missing or misaligned.
• Environment:
• ChatGPT macOS app Version 1.2025.147 (1748653275)
• macOS sequoia 15.5
• Attachment:
Screenshot showing missing underbrace (see attached).
Actual:
Expected:
Unlike the web version of ChatGPT (accessed via browsers like Safari), which renders LaTeX/Mathjax formulas correctly, the ChatGPT Mac app’s implementation is flawed. Many elements render incorrectly, making the feature unreliable and impractical on macOS.
