Https://chatgpt.com/ and Browsers on Mac

Hey @thistlillo, that’s a rough experience, especially when it works fine on your M1.

Short answer: Intel Macs can run ChatGPT in browser, but older hardware + modern web app = lag after a few prompts.

Most common causes:

  • Memory pressure after long chats → things start freezing
  • Extensions interfering (ad blockers, etc.)
  • Hardware acceleration issues on Intel GPUs
  • Long threads getting heavy to render

What’s helped others:

  • Use Chrome/Brave in incognito (no extensions)
  • Turn hardware acceleration off
  • Start a new chat more often
  • Keep fewer tabs open

If one browser felt slightly better, worth tweaking that one further.
